Answer:

This integral is evaluated by dividing the path into infinitesimal segments dL, calculating the scalar product B•dL for each segment, and sum these products. The component of B parallel to dL at each point is always used in evaluating this integral.

The line integral is equal to mu_o × I.

How does Newton's first law affect human motions answer

vazorg [7]

The First Law states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." This simply means that things cannot start, stop or change direction all by themselves. It requires some force acting on them from the outside to cause such a change. Hope this helps! Mark brainly please!

<h3>what is mangetic field?</h3>

magnetic field is a type of field where all things use for magnesium.

The given parameters;

number of turns, N = 1300 turns

diameter of the coil, d = 2.2 cm

initial magnetic field, B₁ = 0.11 T

final magnetic field, B₂ 0

time, t = 12 ms

The area of the coil is calculated as follows;

The emf induced in the coil is calculated as follows;l

A 60 kg runner has 1500 J of kinetic energy. How fast is he moving?

Lapatulllka [165]

The speed with which runner is running is 7.07m/s

<u>Explanation:</u>

Given:

Mass, m = 60kg

Kinetic energy, KE = 1500J

Velocity, v = ?

We know,

Kinetic energy = $\frac{1}{2} mv^2$

On substituting the value we get,

$1500 = \frac{1}{2} X 60 X v^2\\\\v^2 = 50\\\\v = 7.07 m/s$

Therefore, the speed with which runner is running is 7.07m/s

If a 1000-pound capsule weighs only 165 pounds on the moon, how much work is done in propelling this capsule out of the moon's g

yulyashka [42]

Answer:

178200 g mile pounds

Explanation:

Work= Force * Distance= Fh

F=ma=mg where m is mass and g is acceleration due to gravity

Work= 165 pounds *g* 1080 m= 178200 g mile pounds
