Answer:
8.9*10^6 V/m
Explanation:
The expression for electric field strength E is given as
where V= voltage
d= distance of separation
Given data
substituting our given data into the electric field strength formula we have
Explanation:
a)
θ = 4.91 + 9.7t + 2.06t² when t = 0
θ = 4.91 rad
θ = 4.91 + 9.7t + 2.06t²
ω = dθ/dt = 9.7 + 2.06t, when t =0
ω = dθ/dt = 9.7 + 0
ω = 9.7 rad/s
α = d²θ/dt² = 2.06
α= 2.06 rad/s²
b) please use same method above for t = 2.94 s
Your car is performing a transformation of energy of:
Chemical energy to Mechanical energy
The chemical is the gasoline which is then converted to fire as the car runs thus creating the movement of the car which is mechanical energy.
First let us compute for the total growth in population.
Growth = 155 million * 0.01
Growth = 1.55 million
Since there are 12 months in a year, therefore the new
jobs every month should be:
new jobs per month = 1.55 million / 12
<span>new jobs per month = 0.129 million = 129,167 </span>
Answer:
speed = 20 m/s
Explanation:
speed = frequency * wavelength
speed = 4 * 5
speed = 20 m/s
