The object will remain at rest
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Here net force is zero
An object with a net force of zero acting on it will remain at rest, if initially at rest, or it will maintain a constant velocity.
F=MA
Force F=0
Than Acceleration A=0
With zero Acceleration stationary object will remain at rest.
Hence Remain at rest is the correct answer

It would be D. it isn't harmful to anyone unless you are actually unable to do it but if an elderly person is strong enough then sure they can weight lift. And it isn't harmful to adolescents really (unless they drop it on their foot or are too weak or something but that has nothing to do with weight lifting itself... I think I'm getting sidetracked) Anyways if you can weight lift then yes anyone can benefit from it. I hope this helps!
Answer:
A: 15 m/s
Explanation:
If air resistance was not there, then the ball would not stop moving unless your friend, gravity, and the ground catches it.
Answer:
Conduction and convection requires Modes of transfer of heat ! Radiation doesn't require any medium !!
In terms of heat transfer, radiation is the emission of thermal energy in the form of infrared waves. ... Since heat is carried by electromagnetic waves, it does not need a physical medium to transfer it. Instead it radiates through space - this is how the Earth is heated by the Sun despite space being a vacuum
