Answer:

Gravitational potential energy transforms into kinetic energy.

Explanation:

It is given that, we have to write energy transformation occurs when a skydiver first jumps from a plane.

Just before jumping from the plane, the skydive exhibit only gravitational potential energy because it is possessed due to height of an object. It can be given by :

PE = m g h

m is the mass of object

g is acceleration due to gravity

h is the height form the surface

As he reaches down, its potential energy decreases continuously and it is converting to kinetic energy. It can be given by :

KE = 0.5 mv²

V is the velocity of object

So, it is clear that the gravitational potential energy si transforms to kinetic energy.

vagabundo [1.1K]

Answer:

The maximum amount of mechanical energy converted to internal energy during the fall is 26.7 joules

Explanation:

Potential Energy (PE) = weight of baseball × height = 1.47N × 10m = 14.7Nm = 14.7 joules

Kinetic Energy (KE) = 12 joules

Maximum amount of mechanical energy converted to internal energy during the fall = PE + KE = 14.7 joules + 12 joules = 26.7 joules

Answer:

The newton’s second law is F=ma

The Gravitational force is $F=\dfrac{Gm_{1}m_{2}}{r^2}$

Explanation:

Given that,

The equivalent formulas for velocity, acceleration, and force using the relationships covered for UCM, Newton’s Laws, and Gravitation.

We know that,

Velocity :

The velocity is equal to the rate of position of the object.

$v=\dfrac{dx}{dt}$ ....(I)

Acceleration :

The acceleration is equal to the rate of velocity of the object.

$a=\dfrac{dv}{dt}$ ....(II)

Newton’s second Laws

The force is equal to the change in momentum.

In mathematically,

$F=\dfrac{d(p)}{dt}$

Put the value of p

$F=\dfrac{d(mv)}{dt}$

$F=m\dfrac{dv}{dt}$

Put the value from equation (II)

$F=ma$

This is newton’s second laws.

Gravitational force :

The force is equal to the product of mass of objects and divided by square of distance.

In mathematically,

$F=\dfrac{Gm_{1}m_{2}}{r^2}$

Where, m₁₂ = mass of first object

m= mass of second object

r = distance between both objects

Hence, The newton’s second law is F=ma

The Gravitational force is $F=\dfrac{Gm_{1}m_{2}}{r^2}$

Answer:

the answer the correct one is the d

Explanation:

In the gate rotation experiment several things are measured.

- the distance from the hinges to the applied force, which must be measured with a tape measure

- The value of the force that is devised with a dynamometer

- the rotated angle that is measured with a protractor

- the time it takes to turn an angle, which is measured with a stopwatch

Hatshy [7]

Answer:128 N

Explanation:

Sample of 3 cm and 4 mm diameter found to break under a minimum force of 128 N .

If sample is 1.5 cm long with same cross-sectional area then minimum force required to break is also 128 N because the applied force is same for any length and diameter of tendon.
