Answer:
Both the pressure and temperature increase with depth inside the Earth.
Explanation:
The core of the Earth is as hot as the surface of the Sun. The temperature decreases as the distance from the core increases towards the surface of the Earth. The pressure also increases with the depth, though this is not a linear increase with depth. Refer below for variation of pressure with depth inside the Earth.
The triangle stands for change. X means the distance spring stretched or compressed. so together, it's the change in the distance of the spring stretched or compressed.
3.11 is the answer I think
Answer:
<em>The kinetic energy is 600 J</em>
Explanation:
<u>Mechanical Energy</u>
The principle of the conservation of mechanical energy states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.
The mechanical energy is defined as the sum of the potential plus kinetic energies:
E = U + K
Where E is the total mechanical energy, U is the gravitational potential energy and K is the kinetic energy.
Solving for K:
K = E - U
The system described has a total mechanical energy of E=950 J and gravitational potential energy of U=350 J, thus:
K = 950 J - 350 J
K = 600 J
The kinetic energy is 600 J
