The iron is warmer than the shirt. Energy always flows to create equilibrium. And if the energy went from the iron to the shirt, we can conclude the shirt initially had less heat than the iron.
It's basically asking for the acceleration. When an object is in free fall, the acceleration is just gravity. so in this case ∆v = 2.45 because it is the gravity on that planet.
Answer:
1.25 turns
Explanation:
From Transformer equation,
Ns/Np = Vs/Vp............................ Equation 1
Where Ns = Secondary turns, Np = Primary turns, Vs = secondary Voltage, Vp = Primary Voltage.
make Ns the subject of the equation 1
Ns = NpVs/Vp.......................... Equation 2
Given: Np = 100 turns, Vp = 120 V, Vs = 9600 V
Substitute into equation 2
Ns = 100(120)/9600
Ns = 1.25 turns.
Hence the are 1.25 turns in the secondary coil = 1.25 turns
S=d/t this is because speed is just the measurement of time and distance
Falling for 1 second it would have accelerated to 9.8 metres per second
so the answer is 9.8*0.05=0.49m/sec
that is your answer
