Answer:
(a). The velocity of the object is -2.496 m/s.
(b). The total distance of the object travels during the fall is 23.80 m.
Explanation:
Given that,
Time = 1.95 s
Distance = 23.5 m
(a). We need to calculate the velocity
Using equation of motion
Put the value into the formula
(b). We need to calculate the total distance the object travels during the fall
Using equation of motion
Put the value in the equation
The total time is
We need to calculate the distance
Using equation of motion
Put the value into the formula
Hence, (a). The velocity of the object is -2.496 m/s.
(b). The total distance of the object travels during the fall is 23.80 m.
Answer:
yes because of of the constant neutral and no charge
Explanation:
Answer:
The pendulum with the greatest frequency is one with short length.
Explanation:
A simple pendulum is a device which consists of mass m hanging from the string of length L attached to the some point.When displaced and released its swings back and forth with periodic motion.
The frequency of simple pendulum is given by
f = 
where T is the time period.
f =1/2π√g/l
where , l is the length of pendulum
g is acceleration due to gravity.
The frequency of simple pendulum is defined as how much time or the distance covered by the bob in one second
From the given equation we can find that the frequency of the simple pendulum is<em> inversely proportional</em> to square root of length.Hence the frequency will be maximum if the length of the bob is short.
