An object will remain at rest or in uniform motion until acted upon by an external unbalanced source. Ex) a ball remaining still until kicked by a foot.
An object in circular motion has velocity that is constantly changing.
The direction of the acceleration is from the object toward the center of the circular path the object is following.
<span>A lot of things take up electricity. Just leaving something plugged in can cost energy that could have been used for something more worth while. I think the biggest thing people do that wastes energy is that we leave lights on when we don't need them. I would like to improve this method by turning my lights off everytime I exit the room or by not even turning on the light if I can see without it. If it is daylight outside and you have a window in the room and you can see perfectly fine without the light, then why turn it on? No one ever thinks about that. Leaing our lights on is a common factor that raises our light bills. We always think we are gonna come back into the room in a minute but it ends up being a hour later. That's valuable money down the drain because no one is in the room using the light.

Wow ! They could set up sheets of "slow glass" beside beautiful forests with rivers and squirrels and deer and grassy fields, and load a year of this scene into the glass, and then sell it to people who live next to dirty brick walls or ugly empty lots, and those people could install the slow glass in their windows and have beautiful scenery, until it all worked its way out of the glass.
This is a great idea ! If you possibly can, find and read the sci-fi short story "Light of Other Days" written by Bob Shaw, published in Analog Science Fiction in 1966. It's all about this exact type of glass. I read this story in 1966 and I never forgot it ! (Not yet anyway.)
Answer:

Explanation:
Under this condition, . In order to suspend the wire, this magnetic force would have to be equal in magnitude to the gravitational force exerted by Earth on the wire the maximum force at angle
F=ILxB
Now to the suspend the wire so use the maximum force and solve to the current knowing the magnetic field of the earth
∑Fy=0


Solve to I current



I suggest do an toher act is really risk that current for an act
