Which of the following forms of radiation can be shielded by earths atmosphere? Gamma rays,radio waves,visible light, all of the above A. Rob.

Answers

Answer 1

The Earth's atmosphere can shield against various forms of electromagnetic radiation, mostly blocking gamma rays and allowing radio waves and visible light to penetrate. Thus, gamma rays are the form of radiation primarily shielded by our atmosphere.

The Earth's atmosphere provides a natural shield against various forms of electromagnetic radiation, including gamma rays, X-rays, and ultraviolet (UV) light. These types of radiation pose a potential risk to living organisms due to their high energy levels. However, while the atmosphere blocks most gamma rays and X-rays, completely shielding against all electromagnetic radiation is a different matter.

The atmosphere does allow visible light to pass through, enabling us to see the world around us. Radio waves, especially those on the lower frequency end, can also penetrate the atmosphere, which is why we can receive radio signals. On the other hand, gamma rays, which have the shortest wavelength and highest energy, are indeed absorbed by the atmosphere. This absorption is critical for protecting life on Earth from their potentially harmful effects.

To clarify: Gamma rays are mostly absorbed by the atmosphere, radio waves can generally penetrate it, and visible light travels through it to reach the Earth's surface. Therefore, the correct answer to the question about which form of radiation can be shielded by Earth's atmosphere is primarily gamma rays. However, it's worth noting that the question wording implies all of them can be 'shielded' to an extent, but gamma rays are the ones that are most effectively blocked.

B. In order for work to be done the distance must increase.
C. In order for work to be done a force must be transferred and the object must move.
D. In order for work to be done an object must not move.

Answers

C is the correct answer but the best possible answer is that work is done when a force is imposed on an object and the object moves in the same direction as the force

Hope this helps!

Work in physics is done when a force is applied and causes displacement in the direction of the force. The correct answer is that for work to be done, a force must be transferred and the object must move.

In physics, work is defined as the transfer of energy to an object by applying a force that causes the object to move.

The correct answer to what determines whether work is being done is C: In order for work to be done a force must be transferred and the object must move.

For work, in the scientific sense, to occur, a force must be exerted and there must be displacement in the direction of the force.

Formally, the work done is the product of the component of the force in the direction of the displacement and the distance through which the force acts, which is articulated in the equation W = | F | (cosθ) | d |, where W is work, F is the magnitude of the force, cosθ is the cosine of the angle between the force vector and the displacement vector, and d is the displacement.

in the movie The Martian why does Watney need to move away from the HAB?

Answers

Its gonna blow!!! jk running out of oxygen

Final answer:

While the movie The Martian portrays a strong windstorm forcing Mark Watney to move away from the HAB, in reality, Mars' thin atmosphere makes such forceful windstorms unlikely. Watney's movements away from the HAB are more a result of seeking survival solutions than escaping the aftermath of a storm. The movie creatively explores human survival and ingenuity on Mars, though it takes liberties with Martian atmospheric science.

Explanation:

In the movie The Martian, the protagonist Mark Watney, played by Matt Damon, is stranded on Mars due to a strong windstorm that forces his crew to evacuate, thinking him dead. This premise raises intriguing questions about the possibility of such windstorms on Mars. Although the depiction of Mars in the film is largely accurate, astronomers have pointed out that the Martian atmosphere is too thin for windstorms to possess the force shown in the movie. Thus, the scenario dramatized in the film, including the necessity for Watney to move away from the HAB (Habitat Module), stems more from creative license than from scientific accuracy. However, this fictional setup serves as a backbone for exploring human ingenuity and survival in extraterrestrial environments.

Watney's decision to move away from the HAB at different points in the story is driven more by narrative needs and his strategies for survival, such as finding a way to communicate with Earth or traveling to the Ares 4 landing site, rather than by the windstorm's aftermath. The challenges Watney faces and overcomes highlight a powerful message about resilience and the capacity to innovate under dire circumstances.

why does a heating element get hot upon passing current through it? ...?

Answers

In school we learn that some materials carry electricity well, others badly. The good carriers of electricity are called conductors, while the poor carriers are known as insulators. Conductors and insulators are often better described by talking about how much resistance they put up when an electric current flows through them. So conductors have a low resistance (electricity flows through them easily) while insulators have a much higher resistance (it's a real struggle for the electricity to get through). In an electric or electronic circuit, we can use devices called resistors to control how much current flows; using a dial to increase the resistance and lower the current in a loudspeaker circuit is a way of turning down the volume, for example. Resistors work by converting electrical energy to heat energy; in other words, they get hot when heat flows through them. But it's not just resistors that do this. Even a thin piece of wire will get hot if you force enough electricity through it. That's the basic idea behind incandescent lamps (old-fashioned, bulb-shaped lamps). Inside the glass bulb, there's a very thin coil of wire called a filament. When enough electricity flows through it, it glows white hot—so it's really making light by making heat. Around 95 percent or so of the energy a lamp like this uses is turned into heat and completely wasted (using an energy-saving fluorescent lamp is far more efficient, because most of the electricity the lamp consumes is converted into light with hardly any wasted heat).
Heating element got hot upon passing current through it because basically in a conductor, there is no need for ionization in order to have moving charges because of the atom share the electrons
And heating material tend to use the material with higher resistivity

25 kilometers per hour (25 km/h)  is an example of speed only.

Thus, Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path.

In other words, velocity is a vector, whereas speed is a scalar value. For instance, 50 km/hr west denotes the velocity of a car whereas 50 km/hr (31 mph) denotes the speed at which it is moving down a route.

The average speed of an object is determined by dividing the distance traveled by the amount of time it takes the object to go the distance, which is a pretty simple mathematical formula and speed.

Thus, 25 kilometers per hour (25 km/h)  is an example of speed only.

rAl = [tex] \sqrt[3]{pFe/pAl} [/tex]

Hope this helps

Answer:

r = [3 * (pAl/MAl)]/(4 * pi)]^1/3

r = [3 * (pFe / MFe)]/(4 * pi)]^1/3

Explanation:

In the equilibrium state, aluminum and iron have the same mass. From the density equation and solving for the mass we have:

Mass = density/volume

MFe = pFe/V

MAl = pAl/V

In equilibrium, we have that MFe = MAl

Solving for the volume:

MFe = pFe/V

V = pFe/MFe

MAl = pAl/V

V = pAl/MAl

The equation for the volume of a sphere is equal to:

V = (4 * pi * r^3)/3

Replacing the volume of both iron and aluminum, we have:

V = (4 * pi * r^3)/3

r = [(3 * V)/(4 * pi)]^1/3

r = [3 * (pAl/MAl)]/(4 * pi)]^1/3

r = [3 * (pFe/MFe)]/(4 * pi)]^1/3

If energy efficiency is improved, the cost of energy would decrease and _____. more coal would be available less electricity would be used homes would cost significantly less energy star appliances would no longer be necessary

Answers

...less electricity would be used.

Answer:

less energy would need to be generated.

Explanation:

What is efficiency?

Energy efficiency just means that you need less energy for the same consumption or demand.

In distribution and transportation of energy we lose some of the energy generated at the power plants, be it in the form of heat radiation because of the resistance of power cables or in the form of electromagnetic radiation, so if we improve efficiency, then less energy is lost in those two ways to power the same demand. Putting it simply, let's say your house demands 10kW, and the cable connecting you with the utility loses 1kW, then:

1kW+10kW = 11kW <- That needs to be generated

But if we improve that efficiency by 50% then the loses are cut by half, 1kW/2=0.5kW, so:

0.5kW+10kW = 10.5 kW <- 0.5 kW less that need to be generated. Multiply that by the number of homes in America for example and you have  tremendous power-saving potential

two boxes sit on a frictionless surface and are in contact with one another. the first box has a mass of 7 kg and the second box has a mass of 8 kg. A 25 N force is applied to the 7 kg box. Find the acceleration of the boxes. find the force between the boxes

Answers

the acceleration of the boxes depends on the mass and weight. 

we have a mass of 7 and 8 kilograms

if it took 25 N force to move box A, then you would take 25 and multiply by 8 then divide by 2. 

It will leave you with 100 N. 

finally take the sq rt of 100 to get 10

Final answer:

The acceleration of the two boxes on a frictionless surface is 1.67 m/s². The force between the two boxes, as calculated using Newton's second law of motion, is 13.36 N.

Explanation:

To find the acceleration of the two boxes on a frictionless surface that are in contact with each other, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass (F = ma).

The first box has a mass of 7 kg and the second box has a mass of 8 kg. The total mass of the system is therefore 7 kg + 8 kg = 15 kg. When a 25 N force is applied to the 7 kg box, and since there is no friction, this force is the net force acting on the system of both boxes.

The formula for acceleration is a = F/m, where F is the net force and m is the total mass. Substituting our values, we have a = 25 N / 15 kg, which gives an acceleration (a) of 1.67 m/s² (to two decimal places).

Now to find the force between the boxes, we consider that the same acceleration applies to both because they are in contact. The force that the 7 kg box exerts on the 8 kg box is equal to the mass of the 8 kg box times the acceleration. Using F = ma again, we get F = 8 kg x 1.67 m/s², which gives us a force (F) of approximately 13.36 N.

A(n) 0.95-kg bucket is tied to a rope of negligible mass that is wrapped around a pole mounted horizontally on frictionless bearings. The cylindrical pole has a diameter of 0.340 m and a mass of 2.60 kg. When the bucket is released from rest, how long will it take to fall to the bottom of the 20.0 m well?

Answers

The difficulty is to find the acceleration with which the bucket will fall. It will not fall with "g" because of the tension in the rope.

On pole torque ,τ = Tr = Iα where I is moment of inertia of pole =Mr^2/2 and r is the radius of the pole

α = Tr/I ..........................................(1)

Applying newtons law on bucket,

ma = mg-T a=g-T/m .................................................(2)
 
If the rope does not slip

a=αr

g-T/m = Tr^2/I

Putting I = Mr^2/2 ,we get

g-T/m = 2T/M T = g/(1/m+2/M)
 
Putting this value of T in eqn (2), we will get the value of "a" the downward accelration of bucket.

(Please find a by putting the values of m and M yourself).

Now that we know the value of "a", find time taken to travel 20m is very easy.

A package of supplies is to be dropped from an airplane so that it hits the ground at a designated spot near some campers. The airplane, moving horizontally at a constant velocity of 140 km/hr, approaches the spot at an altitude of 0.5 km above level ground. Having the designated point in sight, the pilot prepares to drop the package. How far horizontally from the drop point should the pilot release the package? What is the location of the plane when the package hits the ground?

Answers

s = (140 x 1000 ) / (60 x 60) x root|1000/9.81

Answer:

392.8 m

Explanation:

Horizontal velocity is 38.89 m/s

Vertical distance y =0.5 km = 500 m

First calculate the time in which the package will hit the ground.

Use the second equation of motion

[tex]y = u t + 0.5 at^2[/tex]

[tex]500 = 0 + 0.5 (9.8) t^2[/tex]

t =10.1 s

Horizontal distance covered in the same time is

x = ut = (38.89) (10.1) = 392.8 m

The plane will cover the same horizontal distance in the time in which the package hits the ground.

A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.

When is thermal equilibrium achieved between two objects?









A.
when thermal energy is no longer transferred







B.
when one objects is hotter than the other







C.
when both objects have the same temperature







D.
when the particles in one object have more kinetic energy

Answers

Final answer:

Thermal equilibrium between two objects is achieved when they are at the same temperature, resulting in no net flow of thermal energy between them. This satisfies the conditions of the zeroth law of thermodynamics. So the correct option is C.

Explanation:

Thermal equilibrium is achieved between two objects when both objects have the same temperature, which corresponds to option C. At this point, no thermal energy is transferred between the objects because their molecules have the same average kinetic energy. This concept is rooted in the zeroth law of thermodynamics, which also suggests that if object A is in thermal equilibrium with object B, and object B with object C, then objects A and C are also in thermal equilibrium. Therefore, the net flow of heat ceases once the objects reach the same temperature.

Key Points:

Thermal equilibrium occurs when two bodies can exchange energy but do so without a net energy transfer.Heat is the transfer of energy caused by a temperature difference and stops when temperatures equalize.The zeroth law of thermodynamics justifies the concept of temperature and standard measurement tools like thermometers.
