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.
If we use the sun as a distant object to calculate the convex lens's focal length, we obtain a number that is more closely related to the actual convex lens value.
We need to learn more about a convex lens's focal length in order to locate the solution.
<h3>Why, if we concentrate the sun, do we obtain a focal length that is closer to the correct value?</h3>
- An optical system's focal length is a measurement of how sharply the light converges or diverges.
- The distance between the convex lens's pole and its focus is known as its focal length.
- Convex lenses focus all of the rays from the distant object at their focal point to create a true image.
- We receive a crisper image if the object is farther away from the lens.
- Away from the focal point, an image will form if we concentrate on a neighboring window.
- To get the focal point on a distant tree, we must move the screen in the direction of the lens.
We can therefore draw the conclusion that if we use the sun as a distant object, we will obtain a value that is closer to the convex lens's actual value.

The heavier object has a higher kinetic energy. Kinetic energy is the energy possessed by a body when in motion. It is given by 1/2 mv², where m is the mass and v is the velocity. At a constant velocity, increase in mass increases the kinetic energy. Therefore an object with heavier mass would have higher kinetic energy compared to the lighter energy.
