If u divide the number you'll get on an average of 20km
The nucleus that completes the equation given above is 218/85 At, which is option D.
<h3>What is a nuclear fission?</h3>
Nuclear fission is a nuclear reaction in which a large nucleus splits into smaller ones with the simultaneous release of energy.
According to this question, the following nuclear fission reaction is given: 222/87Fr = 4/2He+ ?
To find the missing nucleus, we subtract 4 from 222 to get 218, therefore, the nucleus that completes the equation given above is 218/85 At.

Answer:
Magnification is approximately 7.71
Explanation:
Magnification is the process of enlarging the apparent size of an object. For two lenses in sequence such as in a microscope, the magnification is determined by the ratio of the focal length of the eyepiece lens to the focal length of the objective lens.
The focal length of a lens is the distance between the center of a lens and the point (focal point) where parallel rays converge after passing through the lens.
= magnification
= focal length of eyepiece lens
= focal length of objective lens

The correct answer to the question is: 78.4 N.
CALCULATION:
As per the question, the mass of the object is given as m = 8 Kg.
We are asked to calculate the force of 8 Kg object pushing up from the table.
The force pushing up from the table is nothing else than the normal reaction.
The normal reaction of the object is equal to the weight of the object as the object is simply resting on the table.
Hence, normal reaction = Weight
= mg
= 8 × 9.8 N.
= 78.4 N.
Here, g is known as acceleration due to gravity.
Hence, the force of the object pushing up from the table is 78.4 N.
