Consider two points in an electric field. The potential at point 1, V1 is 31 V.The potential at point 2, V2 is 168 V. A proton i
hram777 [196]

Answer:

Explanation:

V1 = 31 V

V2 = 168 V

charge on proton, q = e

(a)

The change in potential energy is given by

ΔU = q ( V2 - V1)

ΔU = e (v2 - V1)

(b)

ΔU = e (168 - 31)

ΔU = 137 eV

(c)

Work done = change in potential energy

W = 137 eV

W = 137 x 1.6 x 10^-19

W = 2.19 x 10^-17 J

A wave has a period of 2 seconds and a wavelength of 4 meters. Calculate its frequency and speed. Note: Recall that the frequenc
Angelina_Jolie [31]

Answer:

frequency = 0.5 Hz and speed = 2 m/s

Explanation:

Given that,

The period of a wave, T = 2 s

Wavelength, \lambda=4\ m

If f be the frequency. So,

f = 1/T

f=\dfrac{1}{2}\\\\f=0.5\ Hz

Speed of a wave is given by :

v=f\lambda\\\\v=0.5\times 4\\\\v=2\ m/s

So, the frequency of the wave is 0.5 Hz and speed is 2 m/s.
