Answer:
Explanation:
From the question we are told that
Frequency of light
Generally the equation for wave is mathematically given as
Where
Generally the equation for a fundamental Frequency is mathematically given as
Therefore the length of the smallest standing wave
The period of the pendulum is 8.2 s
Explanation:
The period of a simple pendulum is given by the equation:
where
L is the length of the pendulum
g is the acceleration of gravity
T is the period
We notice that the period of a pendulum does not depend at all on its mass, but only on its length.
For the pendulum in this problem, we have
L = 16.8 m
and
(acceleration of gravity)
Therefore the period of this pendulum is

Answer:
Time, t = 0.25 seconds
Explanation:
Given that,
Force applied by a baseball player, F = 200 N
We need to find the time that baseball player exerts on the baseball if an impulse of 50 Ns is exerted on the baseball. The impulse exerted on the baseball is given by :
t is time taken
So, the time for which the baseball player exerts on the baseball is 0.25 seconds.
