Answer:
v = -0.45 m/s
Explanation:
Assuming the canoe was initially at rest with momentum L = 0
and that the dog's velocity is in the positive direction
conservation of momentum
0 = 15(1.2) + 40v
v = -0.45 m/s
Answer:
A maximum
Explanation:
When displacement is maximum, velocity is Zero and vice versa
When displacement is maximum, acceleration is maximum and when it is zero, acc. Is zero
<span>The property of sound that determine its volume is its AMPLITUDE. The amplitude and the volume of the sound are directly varied. Which means that the larger the amplitude, the larger is the volume and the softer it is if the amplitude is smaller. It is not affected by the motion of the sound source so long as the barriers are not breached. </span>
The ciliary muscles in the eye contract to increase the thickness of the lens, but this is actually a change from distance viewing to close viewing, so the <span>ciliary muscles are relaxing to let you view at a greater distance.
