A closely wound, circular coil with radius 2.80 cm has 790 turns. Part A What must the current in the coil be if the magnetic field at the center of the coil is 0.0760 T

Explanation:

From the question we are told that:

Radius

Turns

Magnetic field B=0.0760

Generally the equation for Magnetic field at the center of the coil is mathematically given by

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

pls mark as brainliest

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
