Answer:

85.556metres

Explanation:

Using pythagorean theorem

C²=A²+B²

we have c as the hypotenuse vector A thus:

93.8²=A²+38.4²

93.8²-38.4²=A²

8794.44-1474.56=A²

7319.88=A²

A=85.556

A 21.3 A current flows in a long, straight wire. Find the strength of the resulting magnetic field at a distance of 45.7 cm from
Bezzdna [24]

Answer:

The magnetic field strength due to current flowing in the wire is9.322 x 10⁻⁶ T.

Explanation:

Given;

electric current, I = 21.3 A

distance of the magnetic field from the wire, R = 45.7 cm = 0.457 m

The strength of the resulting magnetic field at the given distance is calculated as;

B = \frac{\mu_o I}{2\pi R}

Where;

μ₀ is permeability of free space = 4π x 10⁻⁷ T.m/A

B = \frac{\mu_o I}{2\pi R}\\\\B = \frac{4\pi*10^{-7} *21.3}{2\pi(0.457)}\\\\B = 9.322 *10^{-6} \ T

Therefore, the magnetic field strength due to current flowing in the wire is 9.322 x 10⁻⁶ T.

The mass of 29000 N elevator is
Lana71 [14]

<span>In this case we are given a force of 29,000 N. We know that the equation we  can use is:</span>

Force = mass * acceleration

 

However this is not just any type of force, because this is the weight of the elevator. So when the force is equal to weight, the acceleration acting is simply gravity. Therefore:

 

weight = mass * gravity

 

Calculating for mass:

mass = 29,000 N / (9.8 m/s^2)

<span>mass = 2,959.18 kg</span>
