Ug=mgh
assume- the work the gravitational force is the gravitational potential energy=Ug
hence, Ug doesn't depend on velocity/speed, therefore
Ug= (2m) gh
The energy carried by gravitational waves is directly related to the phenomenon of gravitational waves themselves. Gravitational waves are ripples in the fabric of spacetime that carry energy away from accelerating masses, such as merging black holes or neutron stars. The energy carried by gravitational waves is proportional to the amplitude and frequency of the waves, and can be detected by sensitive instruments on Earth.
If the backpack is being carried at a constant speed, there is no change in velocity, which means there is no net force acting on it. Since work is the result of a force acting over a distance, and no force is causing the backpack to accelerate or decelerate, no work is being done on the backpack.
If the box ended up at the same height above the floor as it started, then no gravitational potential energy was added to the box in the form of work. It doesn't even matter if the box moved up or down on the way. Of course, work is done, and calories are expended. That's only because your body is not 100% efficient, and it takes work to move arm and leg muscles, walk, breathe, etc. But no work is done on the box as it moves horizontally.
Potential energy is a form of energy that is not carried by waves. It is stored energy that an object has due to its position or state, such as gravitational potential energy or chemical potential energy.
Group velocity is the velocity of the energy or information carried by a wave packet in a medium. It represents how fast the shape of the wave packet moves through the medium while maintaining its integrity. It can be different from the phase velocity of the individual waves that make up the packet.

Yes, it would. That's one reason why some artificial satellites were tossed into orbit after being carried up aboard the space shuttle. The reason is because escape velocity from Earth depends on Earth's gravity, which in turn depends on the distance from the Earth's center. The higher you go, the farther you are from the center of the planet, the less gravitational force there is between you and the Earth, and the smaller the escape velocity thus becomes.

sand
a machining process carried out on a workpiece with constant cross-section.
It is a device that carried various sizes of fuse to supply power to different areas of the building respectively.
Because we are being carried round with it, and the angular velocity is not sufficient to overcome gravity.

If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.
