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
C.Earth is the largest and most dense of the terrestrial planets
Answer:
A 'kink' in the glass tube which breaks the mercury as it contracts, storing the highest temperature reading. The glass tube is shaped like a lens to magnify the thin mercury thread. Shaking the thermometer resets the mercury back into the bulb.
Answer:
The work done in winding the spring gets stored in the wound up spring in the form of elastic potential energy (i.e potential energy due to change in shape). ... During this process, the potential energy stored in it gets converted to kinetic energy. This turns the wheels of the toy car.
