Explanation:
a 2.35 water bucket is swung in a full cirlce of radius 0.824 m just fast enough so that the water doesn't fall out the top meaning n equals zero there. What is the speed of the water at the top
Answer:
2.84 m/s
Explanation:
At the top position of the circular trajectory, the normal reaction is zero:
N = 0
So it means that the only force that is providing the centripetal force is the gravitational force (the weight of the bucket). Therefore we have:
[tex]mg = m \frac{v^2}{r}[/tex]
where
m is the mass of the water bucket
g = 9.8 m/s^2 is the acceleration of gravity
v is the speed of the bucket
r = 0.824 m is the radius of the circle
Solving for v,
[tex]v=\sqrt{gr}=\sqrt{(9.8 m/s^2)(0.824 m)}=2.84 m/s[/tex]
In which situation will the lowest resistance occur?
Answer:
thick wire and cold temperatures
Answer: There may be two types of resistances here:
Air resistance: for example when something is falling down, the air will push the object upwards. As a bigger surface has the object, more air is pushing, so if you want to reduce the resistance yo must reduce the surface area. For example, a sheet of paper will experience more resistance if it is open if you make a small ball with it.
Electric resistance: This is the resistance of conductors against the electrons that try to travel along with it.
there are two equations here.
R = p*L/A, this talks about the volume and density of the conductor, where p is the density, L is the length and A is the area perpendicular to the direction in which the electricity flows.
Then if you reduce the length, and increase the area, the resistance will be reduced.
the other equation is: R(T) = R0( 1 + a*(T - 20°))
Where R0 is the resistance at 20° and a is a coefficient for T = 20°.
Here, you can see that at smaller temperatures, the resistance decreases, so we can conclude that we must increase the area, and decrease the length and temperature.
A corporation gives out its profits as dividends paid to whom?
Answer: Stockholders
Explanation: stockholders
A corporation gives out its profits as dividends paid to its shareholders.
Who are shareholders?Individuals or organizations that have made financial investments in a firm by purchasing its shares or stocks are referred to as shareholders. When a company makes a profit, it has the option of keeping those earnings in the company for use in future investments or paying those profits out to shareholders in the form of dividends.
The payment of dividends typically takes the form of cash, but they may also be distributed in the form of extra shares of stock or property. The number of shares a shareholder owns in conjunction with the dividend policy of the company determines the amount of dividend money that shareholder receives. One method by which a company can show appreciation to its shareholders for the money they have invested and maintain their support is through the distribution of dividends.

what is meant by the statement" the melting poin of glycerine is 13 degree celsius
Answer:
This means the temperature at which glycerine changes from solid to liquid is 13 degrees Celsius.
Explanation:
Melting point of a substance is the temperature at which it changes from the solid state to liquid state. Heat breaks the intermolecular forces of attractions that holds the substance together.The solid and liquid state are in equilibrium at the melting point. The melting point of a substance depends on pressure, shape of the substance, etc.
The melting point of glycerine at 13 degrees Celsius signifies the temperature at which it changes from solid to liquid at standard atmospheric pressure.
When the statement "the melting point of glycerine is 13 degrees Celsius" is mentioned, it's describing the temperature at which glycerine transitions from a solid to a liquid state under normal atmospheric pressure.
Unlike the triple point, which is the specific temperature and pressure at which a substance's solid, liquid, and gas phases coexist in equilibrium, the melting point is simply the temperature at which the solid and liquid phases are in equilibrium at 1 atm pressure.
For instance, the triple point of water is a more precise calibration temperature than its melting point because it is not influenced by pressure.
A hot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. After it is released, the sandbag encounters no appreciable air drag. Compute the velocity of the sandbag at 0.250 s after its release.
Answer:
[tex]v = 2.55\ m / s[/tex] ↑ upwards
Explanation:
Take the direction up (where the hot-air balloonist moves) as the positive direction, and take the direction down (contrary to the direction of the hot-air balloonist) as the negative direction.
Then we propose the kinematic equation for the speed of the sandbag:
[tex]v (t) = v_0 + at[/tex].
Where
[tex]v_0[/tex] is the initial velocity of the sandbag
a is the acceleration of the sandbag
t is the time in seconds.
In this case
a is the gravitational acceleration of [tex]9.8\ m / s ^ 2[/tex]
[tex]v_0 = 5\ m / s[/tex]
[tex]t = 0.250\ s[/tex]
Now we substitute these values into the formula and solve for [tex]v(t)[/tex]
[tex]v = 5 + (-9.8) (0.250)\\\\v = 5 -9.8 (0.250)\\\\[/tex]
[tex]v = 2.55\ m / s[/tex] ↑ upwards

In which situation is no work being done?
A. a person carrying a box from one place to another
B. a person picking up a box from the ground
C. a person pushing a box from one place to another
D. a person pulling a box from one place to another
In physics, 'work' is a force causing the motion of an object. For work to be done, there must be displacement in the direction of the applied force. In the scenario presented, the situation in which no work is done is when a person is carrying a box from one place to another, as the force and displacement are perpendicular to each other.
Explanation:The concept of 'work' in physics is different from the everyday usage of the term. In physics, work is defined as a force causing the motion—or displacement—of an object. In the concept of work, two key components need to be present: force and displacement in the direction of the force.
With this definition, the scenario where no work is being done is: A. a person carrying a box from one place to another. In this situation, regardless of the weight of the box, if the person carries it horizontally, the force exerted (which is vertically upwards, opposing the weight of the box) and the displacement of the box (which is horizontal) are perpendicular to each other. Since work done is the product of force, displacement, and the cosine of the angle between them, when force and displacement are at 90 degrees, the cosine of the angle is zero and the work done is zero.

Briefly describe what you think the world would be like if the amount of greenhouse gases in the atmosphere were reduced to levels like those during the ice age.
Answer:
If they were reduced to the levels like those during the ice ages, I think the Earth might go back to being frozen again.
Right now, what make the glaciers and polar ice caps melt?
Global Warming and greenhouse gases are depleting the Ozone. The Ozone is what traps the heat from the Sun and radiates it back to the Sun. Greenhouse gas is depleting the Ozone, which means that the heat from the sun is less protected, which results in climate change. It makes the Earth hotter which can mean that the glaciers are melting because the climate in the North and South pole is way to hot for it to stay frozen.
Hope this helped!
Answer: Earth would become frozen and also greenhouse gases reduce the ozone layer which is why glaciers are melting and Earth is getting hotter. It is why greenhouse gases are a big issue.

D.
304.3 N
Answer:
A. 4,440 N
Explanation:
A Force applied on an object with mass 'm' can change its velocity in a unit time. This change is called acceleration.
If a force 'F' is applied on a body of mass 'm', it produces an acceleration 'a' in the body.
Force is give as :
F = ma
In our case,
m = 1200 kg a = 3.7 m/s²
F = 1200 x 3.7
F = 4440 kgm/s²
F = 4440 N

The force at sea level that a boy of mass 40 kg exerts on a chair in which he is sitting is 390 N.
How to calculate the force?Mass of the boy = 40 kg.The direction of that force is always vertically downward.At sea level,
The acceleration due to gravity g[tex]= 9.8 m/s^2[/tex]Then the weight of the boy is the mass of the body itself.m = 40 kg.
Therefore,
w = [tex]40 kg *9.8 m/s^[/tex]
=392 N kg
= 392 N
392N means approximately 390 N.
Hence, the force at sea level that a boy of mass 40 kg exerts on a chair in which he is sitting is 390 N.

#SPJ2
Final answer:
To calculate the force exerted by a 40 kg boy sitting on a chair at sea level, multiply the boy's mass by the acceleration due to gravity (9.80 m/s²) to get 392 N, which is rounded to 390 N, following significant figure rules.
Explanation:
Calculating Force at Sea Level
To calculate the force at sea level that a boy of mass 40 kg exerts on a chair in which he is sitting, we apply Newton's second law of motion. Since we are considering his weight (the force due to gravity), the acceleration in this case is due to Earth's gravity, which is approximately 9.80 m/s². Therefore, the formula to calculate the force (F) is:
F = m x g
Where:
m is the mass of the boy and is given as 40 kg.
g is the acceleration due to gravity and is 9.80 m/s².
Now, we calculate the force:
F = 40 kg x 9.80 m/s² = 392 N.
Following significant figure rules, we round our answer to 2 significant figures because the mass was provided to 2 significant figures. Thus, our final answer is:390 N
