Decide if each description below is an example of a change caused by energy. From the drop-down menu, choose "IS" if it is an ex

ample of a change in energy and "IS NOT" if it is not an example of a change in energy. A fireworks show an example of a change in energy. A child growing an example of a change in energy. A ball on the ground an example of a change in energy. A plant making food from the Sun an example of a change in energy. A car starting an example of a change in energy. A bat hitting a ball an example of a change in energy. An oven heating up an example of a change in energy.

Cindy exerts a force of 40 newtons and moves a chair 6 meters. Her brother Andy pushes a different chair for 6 meters while exer
klasskru [66]
Work formula:
W = F * d
F 1 = 40 N, d 1 = 6 m;
F 2 = 30 N; d 2 = 6 m.
W ( Cindy ) = 40 * 6 = 240 Nm
W ( Andy ) = 30 * 6 = 180 Nm
The difference of their amounts if work:
240 Nm - 180  Nm = 60 nm

A 0.4 m long solenoid has a total of 356 turns of wire and carries a current of 79 A. What is the magnitude of the magnetic fiel
Masja [62]

Answer:

B = 0.088 T

Explanation:

Given that,

The length of a solenoid, l = 0.4 m

No. of turns of wire, N = 356

Current, I = 79 A

We need to find the magnitude of the magnetic field at the center of the solenoid. It is given by the formula.

B=\mu_onI\\\\B=\mu_o \dfrac{N}{l}\times I\\\\B=4\pi \times 10^{-7}\times \dfrac{356}{0.4}\times 79\\\\B=0.088\ T

So, the magnitude of the magnetic field at the center of the solenoid is 0.088 T.
