On a warm, balmy summer day you decide to relax by watching the latest building renovation in your neighborhood. You notice that
1 answer:
Answer:
B) both the amplitude of the motion and the weight of the ball
Explanation:
Time period of a pendulum is given by
where,
L = Length of pendulum
g = Acceleration due to gravity
The system here is similar to a simple pendulum
It can be seen that the time period depends on L and g.
Amplitude and weight are the factors that do not determine the time period.
Hence, the answer is B) both the amplitude of the motion and the weight of the ball

We have here what is known as parallel combination of resistors.
Using the relation:
And then we can turn take the inverse to get the effective resistance.
Where r is the magnitude of the resistance offered by each resistor.
In this case we have,
(every term has an mho in the end)
To ger effective resistance take the inverse:
we get,
The potential difference is of 9V.
So the current flowing using ohm's law,
V = IR
will be, 0.0139 Amperes.
