Kinetic energy of an object depends on its mass and its speed.

If the masses are equal, then the rick with <em>more speed</em> has more kinetic energy.

The rock which is faster than the other have more kinetic energy.

<u>Explanation:</u>

Two rocks are of same mass are rolled down the hill at different speeds. Before the rocks are rolled, at rest they both will have same potential energy and zero kinetic energy. When the rocks are rolled, their potential energy reduces as they move forward and their kinetic energy increases from zero.

Since they are travelling at different speeds, one will be faster than the other, and so one rock reached faster than the other. The rock which reaches the ground first will have more kinetic energy than the other.

VLD [36.1K]
The pulse site located at the point where the upper leg bends is called the femoral. It is an artery found in the thigh. It is large and is deemed as the main arterial supply for the lower part of the body. It is known as the second artery that is the largest. It is being used as the catheter access artery. From it, diagnostics for the heart, brain, arms, kidney and other parts can be directed to the other arterial system. It can also be used as a source to draw blood that is from the arteries when there is low blood pressure.

Answer:

John Dalton

Explanation:

Dalton's atomic theory was the foundation for a new understanding of chemical structures. He proposed that matter was constituted by indivisible and indestructible particles "atoms." He theorized that all atoms of a particular substance were equal, and the atoms of different substances had atoms of different sizes and masses.

He also proposed that all compounds of elements were combinations of elements but in a very precise ratio.

In a certain region of space, the electric field is zero. from this fact, what can you conclude about the electric potential in
eduard
The answer is that it is constant. The relation between electric field and electric potential is given as, E=  -gradient (V).  The E, the partial rate of change of Electric potential, in the equation implies that the V, the partial differential of the potential of the three-dimensional space (assuming it is considered) is constant.
