Answer:
Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.
Explanation:
Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)
Answer:
Actually, surface tension is the to force per unit length. That means formula for surface tension is = force/length . As we know that the dimensional formula for length is L . And that for force is MLT^-2. So the dimensional formula for surface tension can be obtained by dividing the dimensional formula of force and length.
Explanation:
With the values you've given, only velocity can be found.
Acceleration is rate of change of velocity
d= 250s
t= 17s
a= d/t
=
= 4.7
She would weigh less than 50 pounds. everything is super light on the moon. remember that.
Electric power lines in the electric posts hang very low during the summer to prevent overheating. They’re often overloaded with high energy consumption and overheating could cause destruction of conductors. The high temperature could melt or expand the copper and aluminum materials. To protect public safety and guarantee an efficient energy transmission, the power lines are lowered to decrease temperature.
