Explanation:
Given that,
Initial speed of the electron,
Distance, s = 5 cm = 0.05 cm
Acceleration of the electron,
(a) Let v is the electron's velocity when it emerges from this region. It can be calculated as :
v = 871779.788 m/s
or
(b) Let t is the time for which the electron take to cross the region. It can be calculated as:
Hence, this is the required solution.
Answer:
<h3>The answer is 4.29 m/s²</h3>Explanation:
The acceleration of an object given it's velocity and time taken acting on it can be found by using the formula
From the question
velocity = 30 m/s
time = 7 s
We have
We have the final answer as
<h3>4.29 m/s²</h3>Hope this helps you
Answer:
Explanation:
We know that speed is given by dividing distance by time or multiplying length and frequency. The speed of the father will be given by Lf where L is the length of the father’s leg ad f is the frequency.
We know that frequency of simple pendulum follows that
Now, the speed of the father will be while for the child the speed will be
The ratio of the father’s speed to the child’s speed will be
