Elementary charge used to determine charges of other objects is equal to a charge of electron or proton. It's value is roughly
. All other charges are whole-number multipliers of this elementary charge, meaning that we multiply elementary charge by {...,-2,-1,0,1,2,...}.
To find out if the measured charge can be accepted we need to divide it with elementary charge to see if we get whole number as result.
There are three possible values of measured charge:
As we can see none of the possible values of a measured charge is whole-number multiplier of elementary charge so the researcher should not accept the value.
This charge can be achieved by using quarks which have value of 1/3 of elementary charge but they do not remain stable for long enough.
A high deductible plan if that person blames you for it and said that it was on purpose
Time = (distance covered) / (time to cover the distance)
Time = (56.25 m) / (225 m/s)
<em>Time = 0.25 second</em>
Acceleration due to gravity on the surface of radius R = GM/R^2 = 9.8 m/s^2
weight at surface of earth = mg = 78 x 9.8 = 764.4 N
acceleration due to gravity at 6R = GM/(6R)^2
= GM/R^2 /36
=9.8/36 = 0.27 m/s^2
weight on spacecraft = 78 x 0.27 = 21.2 N
