The answer is A. Have you ever heard the saying, opposites attract? That comes from magnetism. Like poles repel each other while opposites attract.
Solar energy or sunlight...
Answer:
L= 2 mH
Explanation:
Given that
Frequency , f= 10 kHz
Maximum current ,I = 0.1 A
Maximum energy stored ,E= 1 x 10⁻⁵ J
The maximum energy stored in the inductor is given as follows
Where ,L= Inductance
I=Current
E=Energy
Now by putting the values in the above equation
L=0.002 H
L= 2 mH
We know that frequency f is given as
C=Capacitance , f=frequency ,L=Inductance
Now by putting the values
Therefore the inductance and capacitance will be 2 mH and 1.26 x 10⁻⁷ F respectively.
The answer is 300 feet. The stop lamp or lamps on the rear of a vehicle must show a red light that is set in motion upon application of the service or foot brake and, in a vehicle manufactured or assembled on or after January 1, 1964, must be visible from a distance of not less than 300 feet to the rear in normal sunlight. Take note, if the vehicle is manufactured or assembled January 1, 1964, the stop lamp or lamps must be visible from a distance of not less than 100 feet. Also, the stop lamp may be combined with one or more other rear lamps.
