Answer:
is the current through the body of the man.
energy dissipated.
Explanation:
Given:
- time for which the current lasted,
- potential difference between the feet,
- resistance between the feet,
<u>Now, from the Ohm's law we have:</u>
is the current through the body of the man.
<u>Energy dissipated in the body:</u>
Explanation:
The pressure on the master piston = the pressure on the slave piston
P₁ = P₂
Pressure is force divided by area:
F₁ / A₁ = F₂ / A₂
Here, F₁ = 20 N, A₁ = 10 cm², and F₂ = 60 N.
(20 N) / (10 cm²) = (60 N) / A₂
A₂ = 30 cm²
The easiest way it to stick it to a metallic surface and then apply an increasing force to pull it with a device that measures the force applied, until the magnet disconnects from the surface.
artic foxes have thick white fur to keep them warm and also for camouflage in the snow they have small ears to keep the snow out of their ears so that they can hear better they also have thick fur lining and a thick pad on their feet this stops the paws from getting cold and they have short legs so then the body weight can be spread making it easier for the animal to not sink in the snow in the summer the artic fox turns brown to help make the fox invisible when people are hunting in the long grass
