direct current I'm positive
No, the sound produced by screeching brakes is not a useful form of energy, because it does not contribute to stopping the car.
Maximum torque on the wire is
It is given that,
Diameter of the wire, d = 11.1 cm = 0.111 m
Radius of wire, r = 0.0555 m
Current, I = 5 A
We need to find the maximum torque on the wire. Torque is given by :
Torque is maximum when,
So, the maximum toque on the wire is . Hence, this is the required solution.
Chemical potential energy
Because you utilize the energy in ur body obtained from eating to throw the football. Thus chemical potential energy
Escape velocity is the point at which the kinetic energy is equal to the gravitational potential energy.
KE = PE
½ mv² = mgh
½ mv² = m (GM/r²) (r)
½ mv² = GMm/r
½ v² = GM/r
v = √(2GM/r)
The escape velocity is independent of the mass of the spacecraft. So the escape velocity will be the same for both X and Y.
