You haven't described the shape of the orbit.
Fortunately, it doesn't matter.
Average speed = (distance covered) / (time to cover the distance)
= (2.0 x 10⁷ meters) / (1 hour)
= 2.0 x 10⁷ meters/hour
= 5,555 and 5/9 meters/second .
Note that this is the satellite's speed.
Regarding velocity:
Velocity = (displacement) / (time for the displacement)
= 10 meters/hour
= 0.002777... meters/second (rounded)
in the direction from the starting point
to the location after that one hour.
Answer:
Potential energy is transfer to kinetic energy,
If radio active substance is decayed.
Answer:
Most of the frogs have webbed feet which helps them swim. The thin skin between the toes helps them to push through the water. The frog's feet is webbed ,So they can easily swim.. The skin between toes are flexible soo they can freely push and pull it
Explanation:
<span>A material through which a current does not move easily is called
an insulator.
Technically, charges CAN move through an insulator, but they lose
a lot of energy doing it, so the current that flows through the insulator
is very very small, usually too small to even measure.
Another way to look at it: Insulators have high resistance.

Answer:
V at C is 3.6 m/s
Explanation:
At A kinetic energy is zero and potential energy=mgh=0.5*9.81*0.6=2.943 J
By conservation of energy.
KE+PE=Constant
At C PE=0.6 J
the KE=2.943-0.6=2.343 J
KE=0.5*m*v^2
v=√[KE/(0.5*m)]=3.06 m/s
