Work done is given by product of force and displacement due to that force
So here we will have
here we know that
Now work done is given as
so it will do 16 J work to move the box
Answer:
Indian girls
Explanation:
I don't know what do you expect I don't know this
Answer:
Explanation:
Given
Mass = m
Time = t
Force = mass × acceleration ..... 1
Where acceleration = velocity/time
Ave Force = m×∆v/∆t
= mv/t
If you ADD those displacements,
(4 km south) + (5 km south) = 9 km south
and
(2 km north) + (5 km north) = 7 km north
Then (9 km south) + (7 km north) = 2 km south
Option C is correct. Frequency can be found by counting the number of troughs per second in a wave diagram.
<h3>What is the frequency?</h3>
Frequency is defined as the number of repetitions of waves occurring in 1 second. It can also be said that Frequency is defined as the number of cycles completed in 1 second.
Frequency is given by the formula as,
Hz.
Hence option C is correct. Frequency can be found by counting the number of troughs per second in a wave diagram.
