What is iencl, the current passing through the chosen loop?

1 answer:

5 0

The concept passing a current through the loop applies the principle of the Ampere's Law. Ampere's law is commonly applied to electricity and magnetism in which it states that "<span>for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop."</span>

Answer:

$a = -1.6\ m/s^2$

Explanation:

<u>Accelerated Motion</u>

It occurs when an object changes its speed over time. If the changes in speed are uniform, then the acceleration is constant, positive if the speed increases, negative if the speed decreases.

The acceleration is calculated as follows:

$\displaystyle a=\frac{v_f-v_o}{t}$

The aeroplane starts with a speed of vo=62 m/s and reaches a speed of vf=6 m/s in t=35 s.

The acceleration is:

$\displaystyle a=\frac{6-62}{35}=-\frac{56}{35}$

$\mathbf{a = -1.6\ m/s^2}$

An elevator accelerates upward at 1.2 m/s 2 . the acceleration of gravity is 9.8 m/s 2 . what is the upward force exerted by the

Marysya12 [62]

We can find the force by using the following formula;
N = ma + mg
Fa = ma = 76 x 1.2 = 91.2
Fg = mg = 76 x 9.8 = 744.8
N = 91.2 + 744.8 = 836
So, the force is 836 N.

Newton's law of universal gravitation states that every object in the universe attracts every other object. true or false.

Oliga [24]

True,According to Isaac Newton believes that Gravity is responsible for drawing attraction which is directly proportional to product of their masses but inversely proportional to the square of the distance between them.
