Be sure to show all 4 steps for each of the problems below.
1. What is the potential energy acquired by a 23 kg paint bucket when it is placed on a
ladder 4 m above the ground? What is the potential energy of the bucket when
it is 10 m above the ground ?

1=920

2=2300

Explanation:

from the question,

M¹=23

H¹=4

g=10(constant)

using the formula

P. E,= mgh

P. E= 23×10×4=920

P. E=23×10×10=2300

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
