Answer:
G=GM/r^2
G=(6.67×10^-11)(6.39×10^23)/(3390000+400000)^2
G=(6.67×10^-11)(6.39×10^23)/(3790000)^2
G=2.967 m/s^2

Answer:
14.7 m/sec.
Explanation:
We will go about using the mathematical formula,
Vf - Vo = gT.
To break it down,
Vf = Velocity of the apple just before hitting the ground.
Vo = Initial velocity of apple = 0
T = Time for apple to hit the ground = 1.5 sec
g = Acceleration due to gravity = 9.8 m/sec^2
We then need to substitute appropriate values,
<em>Vf - 0 = 9.8(1.5) </em>
<em />
<em>Vf = 14.7 m/sec. </em>
<em />
To solve this problem we need to use the induced voltage ratio law with respect to the number of turns in a solenoid. So
For the given values we have to
Replacing we have that,
Therefore the RMS value for secondary is 30V.
The current can be calculated at the same way, but here are inversely proportional then,
Replacing we have
Therefore the rms value of current for secondary is 40mA
