What else can I help you with?
Do you do any work when you lift a load from earth to some height?
yes we do work because work is done against the gravitational field in this case which is equal to w=mgh.
What are some mechanisms that can be invented to lift a load of 200 grams?
If they haven't been invented then they don't have a name.
What is it called when helicopters transport objects by having them hang underneath them?
Helicopter design specs refer to this as an External Load. Commonly referred to as a "sling load". Some helicopters use a hoist to lift objects such as a Search & Rescue helicopter. This is a hoist load.
In height how much will a 2 and a half lift kit put you up?
2 inch lift kits are normally sold as lift blocks so they will lift the vehicle exactly 2 inches. Larger lift kits that achieve their lift with replacement springs will have some variability. This is due to sag over time as well as variations in the exact overall weight of the vehicle.
I am 27 with 6 feet height and 61kg weight how could i gain more weight?
Lift some weights and drink high protein foods.
How do you calculate your 1 rep max?
Although obvious to some, always warm up, stretch, be well hydrated and if using a lift suit make sure it fits properly and when doing max load ALWAYS use a spot!Load bar or have spotter hold dumbbells with the maximum weight you can lift with correct form (!) = your 1 rep max
How does height affect the PE?
Energy can neither be created nor be destroyed. When we lift certain thing to a certain height we have to done some work on it . This energy is stored in the form of potential energy. Potential energy = mass * acceleration due to gravity * Height of object from ground. As height increases PE increases.
What is mean by no load condition?
Commonly relates to devices or equipment which are designed to do some task involving delivery of power, electrical or mechanical. The receiver or this power is called the "load" (for example, a light bulb, or a public lift activated by a motor). If such a load is disconnected (electrically or mechanically) then the arrangement is said to be in a "No Load" condition, and in some cases this might result in some electrical or mechanical failure of the power provider, possibly permanent. Good equipment is designed so that such failures do not occur.
If a hovering helicopter actually travels near 1000 MPH with the Earth's rotation but it is not the laws of motion moving it what is the force moving the helicopter?
The forces acting on the helicopter are lift and gravity. Since the helicopter is at a constant height from Earth, you would assume they are also balanced. In fact the lift is only countering some of gravity's force, while its inertia carries it away from Earth on a tangential path. The unbalanced gravity acts to pull the helicopter back to Earth at the same rate it goes away so it appears the helicopter stays motionless, to a person standing on the ground near the helicopter.
At what height from the surface of the earth the total energy of the satellite is equal to its potential energy at a height of 2R from the surface of earth?
This question cannot be answered because:the total energy of the satellite includes its kinetic energy and that depends on its orbital speed. This is not specified;it is not clear what you mean by "potational": is it a typo for rotational or potential?what is R? The radius of the earth or the height of the satellite or some other measure?
Can children stay short if they lift weights?
No. Height is determined by genetics and nutrition. Certain exercises (such as back squats) can temporarily reduce height if the weight is heavy enough by compressing the distance between the vertebrae. Some men can lose 1/2" of height by doing a squat workout! However, with rest the back will decompress and normal height will be regained..
What energy changes take place when a wheelbarrow is used?
When a wheelbarrow is used, the person pushing it supplies mechanical energy to overcome frictional forces and lift the load. Some of the person's chemical energy from metabolism is converted into kinetic energy to move the wheelbarrow, and potential energy when lifting the load.
