Answer:
Pressure on both feet will be
Explanation:
Weight of the person F = 500 N
Area of foot print
Area of both the foot
We have to find pressure on both the feet
Pressure is equal to ratio of force and area
So pressure
So the pressure on both feet will be when person stands on both feet.
Answer:
The answer your looking for is option 2 - Inertia
Answer:
Explanation:
a ) Between r = 0 and r = r₁
Electric field will be zero . It is so because no charge lies in between r = 0 and r = r₁ .
b ) From r = r₁ to r = r₂
At distance r , charge contained in the sphere of radius r
volume charge density x 4/3 π r³
q = Q x r³ / R³
Applying Gauss's law
4πr² E = q / ε₀
4πr² E = Q x r³ / ε₀R³
E= Q x r / (4πε₀R³)
E ∝ r .
c )
Outside of r = r₂
charge contained in the sphere of radius r = Q
Applying Gauss's law
4πr² E = q / ε₀
4πr² E = Q / ε₀
E = Q / 4πε₀r²
E ∝ 1 / r² .
It’s frequency is high and microwaves can pass through the atmosphere of the Earth.
Yes you need the light or just go outside to get it from the sun
