Answer:
Electric field, 
Explanation:
It is given that, a proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton such that,




or

So, the magnitude of electric field at the location of the proton is
. Hence, this is the required solution.
They should see if there are any sources of bias
Explanation:
The best way to ascertain the reliability of the claim in the article is to see if there is a source of bias.
A source of bias in the article can tell a lot about how reliable and trustworthy the article is. It will also give room to more research about the claim in the article from other sources.
It is possible for some elements of bias to be introduced into a set of observation due to preference and choices.

<u>NO.</u><u> Since </u><u>"c"</u><u> has no dimensions, the value of its exponent </u><u>"n" </u><u>is irrelevant to dimensional analysis, and thus </u><u>dimension analysis </u><u>cannot be used to determine the value of </u><u>"n".</u>
Dimensional analysis is not applicable to proportionality constants, trigonometrical or exponential equations, equation consisting of sum or difference of some quantities and equation consisting of more than three fundamental quantities.
What is Dimensional analysis?
- Dimensional Analysis is a problem-solving technique that makes use of the fact that any number or expression can be multiplied by one without changing its value.
- It is also known as the Factor-Label Method or the Unit Factor Method. It is a practical method.
What is a dimensional analysis used for?
Dimensional analysis is a method used in engineering and the physical sciences to reduce physical properties like acceleration, viscosity, and energy to their three basic dimensions of length, mass, and time (T).

A) The ball on the small ball is far smaller than the force on the basketball.
B) The total momentum before and after the collision remains constant.
C) We know momentum is conserved so we do:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.1 x 5 + 0.6 x 0 = 0.1 x -4 + 0.6 x v₂
v₂ = 1.5 m/s
