<h2>Answer : </h2>
Newton's Third law of motion states :
" Every action has an equal and opposite reaction "
i.e If a force is applied by an object A on another object B then that object B also exerts a foce on object A, that is of same magnitude and opposite direction to the force applied by object A.
Ex - A book on a table exerts gravitational force on the table and table exerts back a normal force on the book.

Explanation:
Answer:
Negative
Explanation:
Liquid electrolyte inside battery has work to transfer the charge from one terminal to other terminal..
So here this is carried out by the charge which has more mobility and it must be more in numbers.
So here for more mobility we have to take the negative charge or free electrons present in the electrolyte which carry electricity from one terminal to other terminal with least resistance
so here correct answer would be
b.) Negative
135 amps
Current is voltage multiplied by power
Answer:
Explanation:
Just before the box starts moving, according to Newton's first law, we have:
The sine of the angle (25°) of a right triangle is defined as the opposite cathetus () to that angle divided into the hypotenuse (W):
The cosine of the angle (25°) of a right triangle is defined as the adjacent cathetus () to that angle divided into the hypotenuse (W):
Recall that the maximum frictional force is defined as:
Replacing (3) in (1) and (4) in (2):
Replacing (7) and (6) in (5) and solvinf for :
