Answer:
Induced current,
Explanation:
Given that,
Area of cross section of the wire,
Time, t = 2.2 s
Initial magnetic field,
Final magnetic field,
Resistance of the coil, R = 8 ohms
The expression for the induced emf is given by :
= magnetic flux
So, the induced emf in the loop is 0.023 volts. The induced current can be calculated using Ohm's law as :
So, the magnitude of the induced current in the loop of wire is . Hence, this is the required solution.
Answer:
The physics behind skydiving involves the interaction between gravity and air resistance.
Explanation:
When a skydiver jumps out of a plane he starts accelerating downwards, until he reaches terminal speed. This is the speed at which the drag from air resistance exactly balances the force of gravity pulling him down.
Pressure is proportional to kinetic energy per unit volume, while temperature is proportional to kinetic energy per particle. ... A gas can be at high temperature and low pressure if it has low number density; likewise, a gas can be at low temperature and high pressure if it has high number density.
So picture below to see answer and explanation.
