Power = Work/time
Work= energy
Potential energy =mxgxh
Power=mxgxh/t
Power=68x10x7/9
Power=529 watts
Answer:
Earth's mass is 5.98 x 1024 kg and has a radius of 6.37 x 106 m. 8.06 N/kg ... what would be the weight of a 70.0-kg student on the surface of Jupiter?Explanation:
All we can say is that the object's volume is about 41 liters. That's the same as the volume of water displaced.
We can't say anything about the object's weight. There is no direct connection between the weight of the object and the weight of the water it displaces.
Answer:
it shows that co2 is absorbed by the atmosphere.

Answer:
acceleration = 22.14 m/s²
time = 2.80 s
Explanation:
given data
initial velocity = 31.0
final velocity =
time = 1.40
solution
we get here acceleration that is
acceleration = 
...............1
acceleration = 
acceleration = 22.14 m/s²
and
by kinematic equation of motion
v = u +at .........2
t = 
time = 2.80 s
