The change in Gravitational Potential Energy (GPE) is actually 0! Think about it:
What is the formula for it?
Well, GPE = mgh.
So, when the height is the same in both cases, we know the gravitational potential energy is the same. Therefore, change in GPE = 0.
Sure, GPE did transform to KE during the swing, but all of that KE transformed back into the original amount of GPE.

Answer:
v = 1.7 m/s
Explanation:
Given that,
Initial velocity of the object, u = 1 m/s
Acceleration of the object, a = 1 m/s²
We need to find the velocity of the object after moving 1 m. Let v be the velocity. Using third equation of kinematics to find it i.e.
So, the final velocity of the object is 1.7 m/s.
Eugene Cernan was not the last, but he was the most recent.
On the off chance that a 2.45 GHz microwave flag is by one means or another radiating from your microwave oven, that is exceptionally perilous and you ought to have it settled or supplanted promptly. A 1000 Watt microwave oven radiating energy into the nearby environment can, contingent upon conditions, make you lose awareness in around 12 to 15 minutes of presentation at a separation of around 10 feet.
