Explanation:
(a) We have,
Length of solenoid, l = 55 cm = 0.55 m
Diameter of the solenoid, d = 10 cm
Radius, r = 5 cm = 0.05 m
Number of loops in the solenoid is 1000.
(a) The self inductance in the solenoid is given by :
A is area
(b) The energy stored in the inductor is given by :
Hence, this is the required solution.
A ratio can be written as a fraction and simplified.
120/3000
simplifies to 12/300
simplifies to 6/150
simplifies to 2/50
simplifies to 1/25
so each 1 pound of force from the jack lifts 25 pounds of car.
Answer : The time taken for a 50 µF capacitor to fully charge if it is in a series circuit with a 100 KΩ resistor is, 0.5 seconds.
Explanation :
RC time constant is the time constant (in seconds). It is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads).
The formula will be:
where,
= time constant = ?
R = resistance = 100 KΩ = 100000 Ω
Conversion used : (1 KΩ = 1000 Ω)
C = capacitance = 50 μF = 50 × 10⁻⁶ F
Conversion used : (1 μF = 10⁻⁶ F)
Now put all the given values in the above formula, we get:
Thus, the time taken for a 50 µF capacitor to fully charge if it is in a series circuit with a 100 KΩ resistor is, 0.5 seconds.
It is possible to throw a 0.145 kg baseball much further than a 7 kg bowling ball, because the 0.145 kg baseball is of a smaller mass than the 7 kg bowling ball and it also offers less resistance to motion and hence it would go further than the 7 kg bowling ball.
True because when the independent answer changes, then the dependent variable, which relies on the independent variable, changes.
