what will happen if you reverse the connction of the coil on a electro magnet I will give Brainliest

Explanation: The poles of an electromagnet can even be reversed by reversing the flow of electricity. If a wire carrying an electric current is formed into a series of loops, the magnetic field can be concentrated within the loops.  All of their little magnetic fields add together, creating a stronger magnetic field.

it is because acrylic blanket have acrylic textile fiber

explanation:

its is better than wool blanket

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
