Answer:
A
Explanation:
Moving the objects together would increase the gravitational force between the object since the closer objects are to each other, since the gravitational force inreases the closer the objects are.
The initial velocity of the potato is 54.41 m/s.
The given parameters:
- <em>Mass of the potato, m = 0.34 kg</em>
- <em>Mass of the cart, m = 5.0 kg </em>
- <em>Velocity of the recoil, u₂ = 3.7 m/s</em>
<em />
The initial velocity of the potato is calculated by applying the principle of conservation of energy as follows;
Thus, the initial velocity of the potato is 54.41 m/s.

Answer:
Inertia
Explanation:
The state of motion of an object is defined by its velocity the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity - and ( in the absence of an unbalanced force ) will remain with a zero velocity.
Answer:
Half-life does not depend on sample size, only on the constituents of the sample.
The second scientist should also observe a half-life of about 232 sec or 40 grams of X remaining after 232 sec.
technically usually the warmer object/substances particles move master which causes friction among the particles plus the kinetic energy being converted to thermal energy, so i would say the hand.
