Well.....
Gravity from the sun pulls the planets torward it while inertia pulls it outward....but I guess that would be why it orbits sorry if this doesn't help but uh

A diver jumps off a diving platform that is 20 meters long. Describe the transfer of energy that occurs during the fall.
kobusy [5.1K]

Answer: gravitational potential energy is converted into kinetic energy

Explanation:

When the diver stands on the platform, at 20 m above the surface of the water, he has some gravitational potential energy, which is given by

E=mgh

where m is the man's mass, g is the gravitational acceleration and h is the height above the water. As he jumps, the gravitational potential energy starts decreasing, because its height h above the water decreases, and he acquires kinetic energy, which is given by

K=\frac{1}{2}mv^2

where v is the speed of the diver, which is increasing. When he touches the water, all the initial gravitational potential energy has been converted into kinetic energy.

Two toroidal solenoids are wound around the same form so that the magnetic field of one passes through the turns of the other. S
dedylja [7]

The concept that we need here to give a proper solution is mutual inductance.

The mutual inductance  is given by the expression

M=\frac{N\Phi}{I}

Where,

I = current

N = Number of turns

\Phi =Flux through the solenoid.

Part A) Then we have in our values that,

I=6.6A

\Phi= 3.50*10^{-2}Wb

N=450

Replacing in the equation,

M = \frac{450*350*10^{-2}}{6.60}

M = 2.39H

Part B) Here is required the Flux, then using the same expression we have that

\Phi = \frac{IM'}{N}

We conserve the same value for the Inductance but now we have a current of 2.6, then

\Phi = \frac{2.6*2.39}{690}

\Phi = 9*10^{-3}Wb

Therefore the flux in Solenoid 1 is 9*10^{-3}Wb
