The period of the pendulum is the reciprocal of the frequency:
The period of the pendulum is given by
where L is the length of the pendulum, and g the acceleration of gravity. By re-arranging the formula and using the value of T we found before, we can calculate the length of the pendulum L:
Answer:
hey mate here is your answer
So if an object has a very small velocity (not moving very far over time, even though a large force may be applied to it, the Power will remain small. ... Stepping on the gas, or "speeding up" the car, is applying a force which will increase velocity and increase power.
please mark me as a brainliest
They best represent a wave with zero energy and zero amplitude.
There are no measurements shown in a table that accompanies
this question having any amplitude or energy greater than zero.
Answer:
It will not change
Explanation:
The period of oscillation of a mass-spring system is given by
where
T is the period
m is the mass hanging on the spring
k is the spring constant
As we see from the formula, the period of oscillation does not depend on the amplitude of the motion: therefore, if we change the amplitude, the time for one oscillation will not change.
Answer:
a) The charge of the capacitor is 4.25x10⁻¹¹C
b) The charge of the capacitor is 4.25x10⁻¹¹C because the battery is disconnected.
c) The potential difference across the plates is 18 V
d) The work is 7.64x10⁻¹⁰J
Explanation:
The capacitance of the capacitor is equal to:
A = 2 cm² = 0.0002 m²
d = 0.5 mm = 0.0005 m
Replacing:
a) The charge of the capacitor is equal to:
Q = C*V = 3.54 * 12 = 42.48 pC = 4.25x10⁻¹¹C
b) The charge is the same because the battery is disconnected (Q = 4.25x10⁻¹¹C)
c) If distance is increased, we have:
The potential is:
d) The work done is equal to:
