The direction of force, when electric current and magnetic field direction given is at 90° to the plane containing current I and Magnetic field B.

<h3>What is magnetic force?</h3>

The force of attraction or repulsion experienced by a magnetic material when it enters the magnetic field.

When a wire with an electric current I is placed in a magnetic field of strength B it experiences a magnetic force F.

According to the Fleming's right hand rule, the direction can be determined by knowing any two parameter's direction.

Thus, The direction of force is at 90° to the plane containing current I and Magnetic field B.

A radioactive decay is illustrated. Which radioactive emission is a product of this decay?
hram777 [196]

The radioactive decay is shown in the image attached to this answer

Answer:

Alpha

Explanation:

An alpha decay is said to have occurred when the mass number of the daughter nucleus decreases by four units and the atomic number of the daughter nucleus decreases by two units.

If we look at the equation from left to right, we will notice that the mass number of the daughter nucleus decreased by four units and the atomic of the daughter nucleus number by two units compared to that of the parent nucleus leading to the emission of an alpha particle.

A machine can never be 100% efficient because some work is always lost due to what?
katrin [286]

A machine can never be 100% efficient because some work is always lost due to the lack of materials or equipment that would convert work by 100%. It follows the second law of entropy. The ideal engine is known as Carnot’s engine having a 100% efficiency. So far, no engine has ever gotten to 100%.
