Answer:
The required net force has a magnitude of 7200 N
Explanation:
Use Newton's 2nd Law to obtain the answer:
Yes indeed, that is a true statement. Truer words are seldom written, and I could not agree with you more.
In case you are asking a question, I can kind of see how this might be a question if there is a blank after "... the change in ..." that is to be filled with one or more new words.
If that is the situation, then the blank can be filled with "frequency or wavelength" .
Answer:
The average force has a magnitude 6524 N due north.
Explanation:
The average net force F = ma where m = mass of car = 1400 kg and a = acceleration.
a = (v - u)/t where u = initial velocity of car = 0 m/s (since it starts from rest)
v = final velocity of car = 27 m/s due north and t = time of motion = 5.8 s
a = (27 m/s - 0 m/s)/5.8 s = 27 m/s ÷ 5.8 s = 4.66 m/s
Since the direction of the velocity change is the direction of the acceleration, the acceleration is 4.66 m/s due north.
The average force, F = ma = 1400 kg × 4.66 m/s = 6524 N
Since the acceleration is due north, the average force takes the direction of the acceleration.
So the direction of the average force is due north
The average force has a magnitude 6524 N due north.

Explanation:
Answer:
The power output of the oscillator is 0.350 watt.
Explanation:
Given that,
Diameter = 1.0 mm
Tension = 5.7 N
Frequency = 57.0 Hz
Amplitude = 0.54 cm
We need to calculate the power output of the oscillator
Using formula of the power
Put the value into the formula
Hence, The power output of the oscillator is 0.350 watt.
