The correct answer should be elastic.

Answer: elastic potential energy

Explanation:

The form of energy stored in the string of the bow is elastic potential energy. Elastic potential energy is the energy stored in an elastic object (such as the string of a bow) when the object is compressed/stretched by a certain amount x with respect to its natural length. The elastic potential energy stored in the object is given by

[tex]U=\frac{1}{2}kx^2[/tex]

How much work is done when a 48-kg stack of books are lifted 2m with a net force of 25 N ?
A. 12.4 J
B. 100 J
C. 50 J
D. 96 J ...?

Answers

Work = force x displacement
W = 25 x 2
W= 50 J

Answer:

C). W = 50 J

Explanation:

As we know that the work done is the product of force and displacement

so here it is given that the net force on the stack of books is 25 N

[tex]F = 25 N[/tex]

also the displacement of the stack of books is 2m as it is lifted upwards

so we have

[tex]d = 2 m[/tex]

now by the formula of work done we know

[tex]W = F.d[/tex]

now plug in all values in it

[tex]W = (25)(2)[/tex]

[tex]W = 50 J[/tex]

a toy car moves 8 m in 4 s at the constant velocity. whats the car's velocity?

Answers


Speed  =  (distance covered) / (time to cover the distance)

           =        (8 m)            /          (4 s)

           =         ( 8 / 4 )  m/s

           =             2 m/s   .  

That 's the toy car's speed.  We can't tell its velocity,
since we have no information about its direction.          

The velocity of the toy car is 2m/s.

HOW TO CALCULATE VELOCITY:

The velocity of a body, also called its average speed, can be calculated by dividing the distance traveled by that body by the time taken. That is;

Velocity (m/s) = Distance (m) ÷ time (s)

According to this question, a toy car moves 8m in 4s. The velocity of the toy car can be calculated as follows:

Velocity = 8m ÷ 4s

Velocity = 2m/s.

Therefore, the velocity of the toy car is 2m/s.

based on the law of conservation of energy. how can we reasonably improve a machines ability to do work? A.move the machine to a different gravitational field B.increase the friction between its moving parts C. reduce the friction between its moving parts or D. redefine the machines system boundaries?

Answers

The correct answer is

C. reduce the friction between its moving parts


In fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

Answer: We can reasonably improve a machines ability to do work by reducing the friction between the moving parts of machine. The correct answer is C.

Explanation:

According to the law of conservation of energy, the energy can neither be created nor destroyed. The energy can be converted from one form to another.

The energy is wasted due to the friction. It reduces the efficiency of the machines to do the work. There will be energy loss due to the friction. By reducing the friction, More energy can be converted into the work.

Therefore, we can reasonably improve a machines ability to do work by reducing the friction between the moving parts of machine.

A falling skydiver has a mass of 105 kg. What is the magnitude of the skydiver's acceleration when the upward force of air resistance has a magnitude that is equal to one-half of his weight?

Answers

f-free = m*g - F_air = m*a

F_air = 1.2 * m

a= (105 kg * 9.8 m.s^2 - 5*105) / 105 kg

a = 9.3 m/s

Hope this helps
Final answer:

The magnitude of the skydiver's acceleration when the upward force of air resistance is half of his weight is 4.9 m/s² downward. This is found using Newton's Second Law and the skydiver's weight calculated from his mass and the acceleration due to gravity.

Explanation:

When the upward force of air resistance is equal to one-half of the skydiver's weight, the net force on the skydiver is only half of his weight acting downward. The skydiver's weight (W) can be calculated using the equation W = mg, where m is the mass and g is the acceleration due to gravity. For a mass (m) of 105 kg and assuming the acceleration due to gravity (g) is approximately 9.8 m/s2, the skydiver's weight would be 105 kg × 9.8 m/s2 = 1029 N. Half of this weight is 1029 N / 2 = 514.5 N.

According to Newton's Second Law (F = ma), the net force is equal to the mass multiplied by the acceleration. In this case, the net force is also the unbalanced force acting on the skydiver, which is half the skydiver's weight. Therefore, we have F = ma, which means 514.5 N = 105 kg × a. Solving for a, the acceleration, we get a = 514.5 N / 105 kg which is approximately 4.9 m/s2. Therefore, the magnitude of the skydiver's acceleration in this case is 4.9 m/s2 downward.

how high did you lift the backpack?
how much did the backpack weigh in pounds

Answers

you did 150.j of work lifting a 120.N back

The backpack was lifted 1.25 meters high, and it weighed approximately 26.977 pounds.

To determine how high you lifted the backpack, we can use the formula for work done against gravity, which is W = F × h, where W is work (in joules), F is force (in newtons), and h is height (in meters). Since you did 150 joules of work to lift a 120-N backpack, we can rearrange the formula to solve for height (h): h = W / F = 150 J / 120 N = 1.25 meters. You lifted the backpack 1.25 meters high.

To find out how much the backpack weighed in pounds, we use the conversion factor that 1 newton is approximately equal to 0.224809 pounds. Therefore, 120 N × 0.224809 lb/N = 26.977 pounds. The backpack weighed approximately 26.977 pounds.

[tex]I \propto V \\ \Rightarrow I=\frac{V}{R}[/tex]

Let the current in the first circuit be I, voltage be V and resistance be R, the,

[tex]I_1=\frac{V_1}{R_1}[/tex]

The voltage in the second circuit is

[tex]V_2=\frac{V_1}{2}[/tex]

The resistance in the second circuit is:

[tex]R_2=2R_1[/tex]

[tex]\Rightarrow I_2=\frac{V_2}{R_2}=\frac{V_1/2}{2R_1}=\frac{I_1}{4}[/tex]

Hence, circuit one has 4 times more current than circuit two.

Fnet = ma = T - mg
m(g/3) = T-mg
T=4mg/3

t = 25 √3

hope this helps
Final answer:

To find the range, maximum height, and speed at impact of a projectile fired with an initial speed of 500m/s and angle of elevation 30 degrees, we can use the equations of projectile motion.

Explanation:

To find the range, maximum height, and speed at impact of a projectile fired with an initial speed of 500m/s and angle of elevation 30 degrees, we can use the equations of projectile motion.

Range: The horizontal distance covered by the projectile is the range. In this case, we can use the formula:

R = (V02 * sin(2θ)) / g

where R is the range, V0 is the initial speed, θ is the angle of elevation, and g is the acceleration due to gravity.

Substituting the given values into the formula, we have:

R = (5002 * sin(2 * 30)) / 9.8

R = (250000 * sin(60)) / 9.8

R ≈ 1450.83 meters

Maximum Height: The maximum height reached by the projectile can be found using the formula:

H = (V02 * sin2(θ)) / (2 * g)

Substituting the given values into the formula:

H = (5002 * sin2(30)) / (2 * 9.8)

H ≈ 3060.45 meters

Speed at Impact: The speed at impact is the magnitude of the velocity of the projectile when it hits the ground. Since the projectile is fired at an angle and lands at a lower height than its initial position, the speed at impact will be lower than the initial speed. However, we need more information to calculate the exact speed at impact.

The radii of the sprocket assemblies and the wheel of the bicycle in the figure are:

2 inches,
and 14 inches respectively.

If the cyclist is pedaling at a rate of 1 revolution per second, find the speed of the bicycle in (a) feet per second and (b) miles per hour.

Answers

Final answer:

To find the speed of the bicycle, we can consider the gearing ratio between the sprocket assemblies and the wheel. The speed in feet per second can be calculated using the cyclist's pedalling rate and the circumference of the wheel. We can use conversion factors to convert the speed to miles per hour.

Explanation:

In order to find the speed of the bicycle, we need to consider the gearing ratio between the sprocket assemblies and the wheel. The ratio of the radii of the sprocket assemblies and the wheel can be used to determine the wheel's rotational speed.

Let's say the cyclist is pedaling at a rate of 1 revolution per second on the sprocket assembly with a radius of 4 inches. The sprocket assembly is connected to another sprocket assembly with a radius of 2 inches, which is then connected to the wheel with a radius of 14 inches.

The ratio of the radii between the sprocket assembly and the wheel is 14/2 = 7.

Therefore, the speed of the bicycle in feet per second can be calculated by multiplying the cyclist's pedalling rate by the circumference of the wheel:

Speed (feet per second) = 1 revolution/second x 2π x 14 inches = 28π inches/second = 28π/12 feet/second

To find the speed of the bicycle in miles per hour, we can convert the speed from feet per second to miles per hour:

1 mile = 5280 feet and 1 hour = 3600 seconds, so:

Speed (miles per hour) = (28π/12 feet/second) x (5280 feet/1 mile) x (1 hour/3600 seconds)

Answers

Correct answer choice is :


C) The freezing and melting temperatures of a substance are the same.


Explanation:


Fluids have a particular temperature at which they convert into solids, identified as their freezing point. In theory, the melting point of a solid should be the same as the freezing point of the liquid. In practice, small variations among these measures can be seen. The freezing point of a matter is the same as that substance's melting point. At this distinct temperature, the substance can exist as either a solid or a liquid. At temperatures below the freezing/ melting point, the substance is a solid.


Answer: The correct answer is "The freezing and melting temperatures of a substance are the same".

Explanation:

Freezing temperature: It is the temperature at which the liquid becomes the solid.

Melting temperature: It is the temperature at which the solid starts converted into liquid.

The freezing point of a substance is the same as the melting point of the substance. During melting and freezing of the substance, the temperature remains same as the energy is spent in changing the phase of the substance not in changing the temperature.

Latent heat is there. It is a hidden heat. It is required to change phase of the substance without showing temperature on thermometer.

Boiling temperature: It is the temperature at which liquid gets converted into vapors. At this temperature, vapor pressure of the liquid equals to the pressure surrounding the liquid.

Answers

Final answer:

The VW Beetle takes 25.53 seconds to reach a speed of 60.0 mi/h with an acceleration of 2.35 m/s². The top-fuel dragster has an acceleration of 22.36 m/s² to go from 0 to 30 mi/h in 0.600 seconds.

Explanation:

To calculate the time it takes for the VW Beetle to reach a speed of 60.0 mi/h, we need to use the equation v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time taken. Rearranging the equation to solve for t, we have t = (v - u) / a. Plugging in the values, we get t = (60.0 mi/h - 0) / 2.35 m/s² = 25.53 s.

To find the acceleration of the top-fuel dragster, we use the equation a = (v - u) / t, where a is the acceleration, v is the final velocity, u is the initial velocity, and t is the time taken. Rearranging the equation to solve for a, we have a = (v - u) / t. Plugging in the values, we get a = (30 mi/h - 0) / 0.600 s = 50 mi/h/s = 22.36 m/s².
