9.19 seconds (2dp)

Given:

v = 50m/s

u = 0 m/s

a = 5.44 m/s

t = ?

Substitute values into the equation v = u + at

v = u + at

50 = 0 + 5.44 x t

t = 50/5.44

t = 9.19 seconds

Time is in seconds as the velocity and acceleration are in metres per second instead of kilometres per hour

A 1300-turn coil of wire that is 2.4cm in diameter is in a magnetic field that drops from 0.15T to 0 T in 12ms . The axis of the

krek1111 [17]

The emf induced in the coil at the given magnetic field strength is 4.53 V.

<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

Thus, the emf induced in the coil at the given magnetic field strength is 4.53 V.

The speed of light is 3.0 x 10^8 m/s. If the wavelength of a light wave is 5.8 x 10^-7 m, what is its frequency

ddd [48]

Answer:

The frequency is 517.24 THz

Explanation:

Given:

The speed of light = 3.0 x $10^{8}$ m/s

The wavelength of light wave = 5.8 x $10^{-7}$ m

Frequency = ?

We know that the relation among speed of light, wavelength and frequency is given by

c = νλ , where

c is speed of light

ν is the frequency

λ is the wavelength

To find the frequency(ν):

ν = c / λ

= $\frac{3.0 x 10^{8} ms^{-1} }{5.8 x 10^{-7}m }$

= $\frac{3}{5.8}$ x $10^{15}$

= (3000/5.8) x $10^{12}$

= 517.24 x $10^{12}$ $s^{-1}$

= 517.24 x $10^{12}$ Hz (since 1 $s^{-1}$ = 1 Hz)

= 517.24 THz (Tera Hertz)

Hence the frequency is 517.24 THz.
