Answer:
Time=15,Mass=3,Acceleration due to gravity=10,Height=50,Power=?.
Power=mgh/t.....which is 3×10×50=1500/15=100Watts.
Answer:
pretty sure A is correct, as they are pushing in opposite directions, hence canceling each other
Explanation:
D=Vot+1/2at^2
In this case, there is no initial y velocity so the term Vot=0 so d=1/2at^2
acceleration=acceleration due to gravity=-9.8m/s^2
It falls - 22cm or -0.22m
We have - 0.22=1/2(-9.8)t^2
t^2=(-0.44)/(-9.8)
t=sqrt[0.44/9.8]
Burning coal to create power pollutes the air. Not sure if it's the answer you're looking for as the answers are not given to me.
When discussing magnetic fields we could say that metals can become magnetic if they have many spinning electrons that create magnetic fields.
