Si un cuerpo se encuentra en reposo tiene energía cinética?¿por qué?​
posledela

Answer:

This is because, when an object which has possessed kinetic energy under its being in motion hits another object, which is stationary the object at rest receives part of the energy inherent in the body which has kinetic energy and expresses the received energy in the form of motion or some forms different from the initial stationary position.

A magnetic field is used to suspend a wire of mass 0.05 kgkg and length 0.16 mm . The wire is carrying a current of 11 AA . What
pochemuha

Answer:

B=0.27840\ T

Explanation:

Given:

mass of the wire, m=0.05\ kg

length of the wire, L=0.16\ m

current in the wire, I=11\ A

Now form the Lorentz force we know that every current carrying wire experiences a magnetic force on it due to the magnetic field components perpendicular to it.

Mathematically given as:

F=I.L\times B

m.g=I.L\times B

here: we nee to balance the gravitational force on the mass.

B= magnetic field

0.05\times 9.8=11\times 0.16\times B

B=0.27840\ T

This magnetic field must be perpendicular to the direction of current in the wire and the these two directional quantities must lie in a plane normal  to the direction of gravity according to the Fleming's left hand rule.
