False....................................
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
Answer:
in simple harmonic motion, the formula for finding amplitude is:
a = -ω^2 x
where, a=amplitude, ω= angular frequency, x= Displacement
Explanation:
The answer is C, as the frequency gets higher the wavelength gets shorter
20 meters per second at 30 seconds.
Multiply 20 meters by the amount of seconds. 20*30 = 600 meters.
