Answer:
2.1 cm
Explanation:
The general equation for the graph is:
y = A cos(ωt + ∅)
A: amplitude, is the maximum and minimum value for y(t)
mass and acceleration have a nice day
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
Increased the temperature in the room, which means an increase in the airs connect molecular energy
Answer:
frequency = 0.5 Hz and speed = 2 m/s
Explanation:
Given that,
The period of a wave, T = 2 s
Wavelength, 
If f be the frequency. So,
f = 1/T

Speed of a wave is given by :

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