Answer:
Explanation:
Given
for
Sphere are
when sphere apart suppose deflection is
We know
Where F=force between charged particle
Deflection
thus
for
(b)for deflection Potential
Electric Potential is
where V=voltage
k=constant
r=distance between charges
Put value of Q in equation 1
thus
therefore
Divide 3500km by 3h (according to the equation v = d/t) and you get 1167km/h.
Answer: E = 0.85
Therefore the efficiency is: E = 0.85 or 85%
Explanation:
The efficiency (e) of a Carnot engine is defined as the ratio of the work (W) done by the engine to the input heat QH
E = W/QH.
W=QH – QC,
Where Qc is the output heat.
That is,
E=1 - Qc/QH
E =1 - Tc/TH
where Tc for a temperature of the cold reservoir and TH for a temperature of the hot reservoir.
Note: The unit of temperature must be in Kelvin.
Tc = 300K
TH = 2000K
Substituting the values of E, we have;
E = 1 - 300K/2000K
E = 1 - 0.15
E = 0.85
Therefore the efficiency is: E = 0.85 or 85%
