E is always less than or equal to Eo, so the dielectric constant is greater than or equal to 1. The larger the dielectric constant, the more charge can be stored, therefore its greater most of the time
Explanation:
It is given that,
Inductance of the inductor,
Resistance of the resistor, R = 10 ohms
(a) Let is the time constant of the circuit. It is given by :
(b) The current equation in RL circuit is given by :
I' = 0.99 I
t = 4.6 ms
Hence, this is the required solution.
Answer:
d = 7200 m
Explanation:
Given that,
Average speed of a runner, v = 2 m/s
Time taken by the runner, t = 60 min = 3600 s
We need to find the distance covered by the runner.
Speed = distance divided by time taken.
v = d/t
Putting all the values,
So, the distance covered by the runner is 7200 m.
Answer:
Note that the static friction force acting on the front wheels is the force that accelerates the car forward. It is considerably larger than the friction force on the rear wheels - all that force has to do is to provide sufficient torque to give the rear wheels the correct angular acceleration.
Explanation:
Answer:
An element's mass number (A) is the sum of the number of protons and the number of neutrons. ... Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers.
