Astronomers think Jupiter generates its internal heat by contracting, changing gravitational potential energy into thermal energy.

Answer: Option E

<u>Explanation:</u>

The internal heat of Jupiter is primarily the primary heat released during gravitational collapse when its creation occurs. Because of their large dimensions, this giant plant was heavily heated by creating surrounding material on their cores.

The largest planet, Jupiter was the hottest. Part of this warming may still remain on such large planets. In addition, it is possible that this giant, mainly gaseous planets produce heat after they are formed as a result of slow contraction. With such a large mass, even a small shrinkage can generate high heat.

mixer [17]

Answer:

0.07142 m/s in the opposite direction of the bullet

Explanation:

$m_1$ = Mass of rifle = 70 kg

$m_2$ = Mass of bullet = 0.01 kg

$v_1$ = Velocity of rifle

$v_2$ = Velocity of bullet = 500 m/s

As the momentum of the system is conserved

$m_1v_1+m_2v_2=0\\\Rightarrow v_1=-\frac{m_2v_2}{m_1}\\\Rightarrow v_1=-\frac{0.01\times 500}{70}\\\Rightarrow v_1=-0.07142\ m/s$

The recoil velocity of the rifle is -0.07142 m/s

The negative sign shows the opposite direction of the rifle.

Tresset [83]

Answer:

Given:

Fundamental frequency: 470Hz

T1:310k,T2:315k

Calculating velocity

Recall v=(331m/s)✓[T1/273k)

V=331✓(310/273)

V1=331*(1.0656)=352.72m/s

V2=331✓(315/273)=355.5m/s

Fundamental frequency=4L

F2=F1(V2/V1)

F2=470(355.5/352.72)=474.4Hz

Beat=[F2-F1]=474.4-470=4.4Hz
