A strip of copper 190 µm thick and 4.20 mm wide is placed in a uniform magnetic field of magnitude B = 0.78 T, that is perpendic

Veronika [31]

Answer:

V = 9.682 × 10^(-6) V

Explanation:

Given data

thick = 190 µm

wide = 4.20 mm

magnitude B = 0.78 T

current i = 32 A

to find out

Calculate V

solution

we know v formula that is

V = magnitude× current / (no of charge carriers ×thickness × e

here we know that number of charge carriers/unit volume for copper = 8.47 x 10^28 electrons/m³

so put all value we get

V = magnitude× current / (no of charge carriers ×thickness × e

V = 0.78 × 32 / (8.47 x 10^28 × 190 × 1.602 x 10^(-19)

V = 9.682 × 10^(-6) V

The potential difference between A and B is 5.0 V. A proton starts from rest at A. When it reaches B what is its kinetic energy?

Aleksandr [31]

Answer:

total kinetic energy is 8 × $10^{-19}$ J

Explanation:

given data

potential difference = 5 V

e = 1.60 × $10^{-19}$ C

to find out

what is kinetic energy

solution

we will apply here conservation of energy that is

change in potential energy is equal to change in kinetic energy

change potential energy is e × potential difference

change potential energy = 1.60 × $10^{-19}$ × 5

change potential energy = 8 × $10^{-19}$ J

so change in kinetic energy = 8 × $10^{-19}$ J

and we know proton start from rest that mean ( kinetic energy is 0 ) so

change in KE is total KE

total kinetic energy is 8 × $10^{-19}$ J
