Answer:
A C
Explanation:
The statement of the exercise is a bit strange, but if the distance between the load increases.
The following phenomena must occur.
* If the charge has a spatial distribution, the electric field should reduce the electric field of a point charge at the same distance
* As the distance increases the value of the electric field decreases in quadratic form
therefore when reviewing the correct answers are
if the total load is q, answer A is correct
and answer C is always correc
Answer:
v = rw
Explanation:
When an object is rolling continuously without slipping, then every angle it rotates through, is equal to a distance the perimeter has rotated.
If the object completes 10 revolutions and takes a particular time, let's say t to complete it. The angular distance would then be 20 π rad, while its angular velocity will be 20 π/t
The circumference will somehow translate to the distance it covers, which is 20πr, this means that the speed is 20πr/t
So, like the question asked, the linear speed compared to angular speed is
v : w
20πr/t : 20πt, which can be simplified to
r : 1
In essence, v = rw
0.022 has 2 digits because you would count from the left starting with the first nonzero number
