Answer
The rate at which the magnetic field is changing is
Explanation
From the question we are told that
The electric field strength is
The radius is
The rate of change of the magnetic field is mathematically represented as
Where is change of a unit length
Where A is the area which is mathematically represented as
So
where L is the circumference of the circle which is mathematically represented as
So
substituting values
1 km = 1000 m
1 min = 60 s
Entonces
60 km/min * (1000 m/km) * (1/60 min/s) = 1000 m/s
Answer:
Funny answer but works!
Explanation:
Not enough air. Go outside, crack open the window and blow air into the room like you would a balloon then close the window quickly. If it doesn't start bouncing, try giving the house a push. Good luck.
<span>1. Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes. The following explains why many modern electronic devices use integrated circuits instead of vacuum tubes:</span>
They are much smaller and more efficient than vacuum tubes.
<span>2. The equation that is used to calculate the amount of electrical energy is the following:
E=P x tE is the energy transferred in kilowatt-hours, kWhP is the power in kilowatts, kW</span>
t is time in hours, h
3. The term voltage describes the work done per unit of charge against a static electric field to move the test charge between two points. It is <span>an electromotive force and also referred to as potential difference. Voltage is expressed in volts. (V). from the given explanations the following is true:</span>
<span>It is the difference in electrical potential energy between two places in an electric field.</span>
