Answer: energy transformation
Answer: Visible light makes up 35% of natural light.
Answer:
so initial momentum is 0.22kgm/s
Explanation:
m1=0.20kg
m2=0.30kg
initial velocity of m1=u1=0.50m/s
initial velocity of m2=u2=0.40m/s
total momentum of the system before collision
Pi=m1u1+m2u2
Pi=0.20kg×0.50m/s+0.30kg×0.40m/s
Pi=0.1kgm/s+0.12kgm/s
Pi=0.22kgm/s
GPE=mass*GFS*height
2kg*9.8N/Kg*40m -I've used the Grabitational field strength of the earth's
surface
=784J
Answer:
no
Explanation:
because will the cool air will be leaving the fridge the motor in the bottom will be running and eventually the mixture of the cool and hot air will balance out
