Answer :
Explanation :
It is given that,
length of pendulum, l = 0.6 m
Number of oscillation, n = 20
time, t = 35.5 seconds
so, Time period, 
we know that the time period of pendulum is given by
or
Because they are larger planets the gravitational pull is heavier and they attract more celestial bodies

<span>The correct answer is A. drive the compressor. It's not D because the compressor compresses it, not the turbine. The temperature and the velocity of gasses are unrelated to this. There are in fact two turbines, and the first one gets power from exhaustion, which is then used to power to turbine in the turbojet that is used to drive the compressor. This is how turbojets commonly work.</span>
Answer:
Δv = 12 m/s, but we are not given the direction, so there are really an infinite number of potential solutions.
Maximum initial speed is 40.6 m/s
Minimum initial speed is 16.6 m/s
Explanation:
Assume this is a NET impulse so we can ignore friction.
An impulse results in a change of momentum
The impulse applied was
p = Ft = 1400(6.0) = 8400 N•s
p = mΔv
Δv = 8400 / 700 = 12 m/s
If the impulse was applied in the direction the car was already moving, the initial velocity was
vi = 28.6 - 12 = 16.6 m/s
if the impulse was applied in the direction opposite of the original velocity, the initial velocity was
vi = 28.6 + 12 = 40.6 m/s
Other angles of Net force would result in various initial velocities.
