mark it as a brilliant answer
Answer:
A
Explanation:
paddling a canoe to make the boat move
Answer:
2. displacement is maximum
Explanation:
This makes sense as the spring is stretched the farthest at this point
F = kx
The largest force makes the largest acceleration.
<span>The time it takes for one wavelength to pass a fixed point is known as PERIOD.
In fact, the period is defined as the time it takes a wave to make one complete oscillation: since the wavelength is the distance between two consecutive points of the wave with same shape, it means that the time it takes for one wavelength to pass a fixed point in space is exactly the period.</span>
Answer:
5)
Solution
initial velocity = 15 m/s
acceleration = 3m/s^2
time = 4 s
final velocity = 15+3×4
=15+12
=27m/s
A car accelerates from 20m/s to 30m/s in 10 second
T9 be honest I think some part of the second question is missing
