Boxes A and B are in contact on a horizontal, frictionless surface. Box A has mass 21.0 kg and box B has mass 8.0 kg. A horizont

vfiekz [6]

Answer:

2.75 N

Explanation:

Given that,

Box A has a mass 21.0 kg and box B has a mass 8.0 kg.

A horizontal force of 100N is exerted on box A.

Let a be the acceleration of the system. Using second law of motion,

$F=(m_A+m_B)a\\\\a=\dfrac{F}{(m_A+m_B)}\\\\a=\dfrac{10}{(21+8)}\\\\a=0.344\ m/s^2$

Now applying Newton's second law to box B. So,

$F_A=m_Ba\\\\=8\times 0.344\\\\=2.75\ N$

So, 2.75 N is the force that box A exerts on box B.

Producing a current by moving a wire through a magnetic field is called “BLANK” induction

NeX [460]

Producing a current by moving a wire through a magnetic field is called ELECTROMAGNETIC INDUCTION.
Electromagnetic induction refers to the production of an electromotive force across an electrical conductor in a changing magnetic field. The process was discovered by Micheal Faraday in 1831.
