Answer:
The phrases the describe the situation are A and C
Explanation:
1- If a car is at rest or uniform motion, it will remain in that condition until an external force acts on it. If the external forces acting on a body are balanced , it means that their sum is equals to 0, which eventually results that no Net force is acting on it.
For balance forces, ∑F = 0
2- If the car moving at a constant speed is slowing down, it means that the forces have become unbalanced, eventually resulting in a Net force in the opposite direction of the motion of the car, due to which it is slowing down
For unbalanced forces, ∑F ≠ 0
The question satisfies 2, which is the answer
The maximum velocity of the rock is 64.55 m/s
Answer: Option B
<u>Explanation:</u>
The possessed energy by the objects while motion called kinetic energy. It is directly proportionate to mass and square of velocity. The stored energy in the system called potential energy and expressed as below,
U = spring’s potential energy in certain place
k = the spring constant, in N/m.
x = the spring’s distance is stretched or compressed away from equilibrium
Conservation of energy states energy neither created nor destroyed but change from one form to other. So, using this concept, equating both potential and kinetic energies equation we get,
Given:
m = 12 g = 0.012 kg
k = 200 N/m
x = 0.500 m
Substitute these values we get,
Taking square root, we get,
MY personal interpretation of nothing is no atoms or particles of anything. but keep in mind im 11 <span />
A ) decrease.
B ) increase.
C ) increase, then decrease.
D ) not change.
The answer is A) decrease
Take pushing a box, for example-- You push your hardest then give out, still trying to push the box. You are doing less work than what you have started with!
( Mind marking me for branliest? ; ) )
Because they are mentally trying to extinguish the negative things in their lives and focus on the positive things
