Answer:
E) e
Explanation:
Impulse is equal to the product between the force applied (F) and the time interval of the collision (
):
This means that we can calculate the force for each collision dividing the impulse by the time interval:
Let's apply the formula to each case:
A) 
B) 
C) 
D) 
E) 
Therefore, the force is the maximum for collision E).
Answer:
The group that is exposed to the variable to be tested is called as experimental group.
Explanation:
An experiment consists of two kinds of group. They are experimental group and control group. The working of control group and experimental group are mostly same except that the variables will be changed in experimental group, while it is kept constant in control group. So at the end of experiments, the results from control group and experimental group are compared and the final outcome has been derived. So the given statement where the group is exposed to the variable to be tested or the independent variable is called as experimental group.
The force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.
<h3>Force on the charge</h3>
The force on the charge is calculated as follows;
F = k(q1q2)/r²
where;
- r is the distance between the charges = 2 m - 1m = 1m
F = (9 x 10⁹ x 10⁻⁹ x 2 x 10⁻⁹)/(1)²
F = 1.8 x 10⁻⁸ N
Thus, the force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

a compound microscope is used for viewing samples at high magnification<span> 40 - 1000x, which is achieved by the combined effect of two sets of lenses: the ocular lens in the eyepiece and the objective lenses close to the sample.</span>
Answer:
a) interior, b) inside, c) minor
Explanation:
In this exercise you are asked to select the correct words so that the statements have been correct
Electric charges always repel each other when they are of the same sign, in conductors this has the consequence that charges accumulate on the surface and the interior remains without electric charges. with this we analyze the statements
a) interior
b) inside
c) minor
therefore the phrase would be:
(a) The net charge is always zero ---INTERIOR--- the surface of an isolated conductor.
(b) The electric field is always zero ---INSIDE--- a perfect conductor.
(c) The charge density on the surface of an isolated, charged conductor is highest where the surface is ---MINOR---to)
