Answer:
-322.64 J
Explanation:
75 N * cos 125 * 7.5 = -322.64 J
False because currents do not flow easily through insulators. If it only said conductors, then it would be true.
Answer:
I. 0 m/s
II. 20 m/s
III. Part BC
Explanation:
I. Determination of the initial velocity.
From the diagram given above,
The motion of the car starts from the origin. This implies that the car start from rest and as such, the initial velocity of the car is 0 m/s
II. Determination of the maximum velocity attained.
From the diagram given above, we can see clearly that the maximum velocity is 20 m/s.
III. Determination of the part of the graph that represents zero acceleration.
It important that we know the meaning of zero acceleration.
Zero acceleration simply means the car is not accelerating. This can only be true when the car is moving with a constant velocity.
From the graph given above, the car has a constant velocity between B and C.
Therefore, part BC illustrates zero acceleration.
Answer:
A I think
Explanation:
because what is the most frequency a because it has more frequency I think I'm not that sure
heat from water goes into air in ball
air expands
ping goes the dent
