Answer:

112.5 m

Explanation:

d = vo . t + ½ a t²

d = distance

vo = initial velocity

t = time

a = acceleration

d = 10 . 5 + ½ . 5 . 5²

d = 50 + 62.5

d = 112.5 m

A grating that has 3900 slits per cm produces a third- order fringe at a 28.0° angle. What wavelength of light is being used? Ex

Zolol [24]

Explanation:

Given that,

Number of slits per cm, $N=3900\ lines/cm=390000\lines/m$

The third fringe is obtained at an angle of, $\theta=28$

We need to find the wavelength of light used. The grating equation is given by :

$d\ sin\theta=n\lambda$

$d=\dfrac{1}{N}=\dfrac{1}{390000}$

$d=2.56\times 10^{-6}\ m$

$\lambda=\dfrac{d\ sin\theta}{n}$ , n = 3

$\lambda=\dfrac{2.56\times 10^{-6}\times \ sin(28)}{3}$

$\lambda=4.006\times 10^{-7}\ m$

$\lambda=400\ nm$

So, the wavelength of the light is 400 nm. Hence, this is the required solution.

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.
