An independent variable :)) hope I helped
To start with solving this
problem, let us assume a launch angle of 45 degrees since that gives out the
maximum range for given initial speed. Also assuming that it was launched at
ground level since no initial height was given. Using g = 9.8 m/s^2, the
initial velocity is calculated using the formula:
(v sinθ)^2 = (v0 sinθ)^2
– 2 g d
where v is final
velocity = 0 at the peak, v0 is the initial velocity, d is distance = 11 m
Rearranging to find for
v0: <span>
v0 = sqrt (d * g/ sin(2 θ)) </span>
<span>v0 = 10.383 m/s</span>
The answer would be A, since at that position the Earth is fully/partially being engulfed in a shadow cast by the moon from the sun’s rays.
Hope this helps!
Answer: The pressure from the air and force of who or what used effort to make it move. For example you roll a ball it doesn't stop unless it runs out of the force which in this case would be energy.

Knowledge
Answer:
45500 J
Explanation:
Pressure, P =350 kPa = 350 x 1000 Pa
V1 = 0.02 m^3
V2 = 0.15 m^3
Work done by the piston
W = Pressure x increase in volume
W = P x (V2 - V1)
W = 350 x 1000 (0.15 - 0.02)
W = 45500 J
Thus, the work done is 45500 J.
