Answer: Newton's third law
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Answer:
2400 km
Explanation:
30km for 1hr
Need up to 80 hrs , multiply both 80 and 30
So its 2400km
Answer:
(a) 152.85 Nm
(b) 1528.5 Nm
Explanation:
According to the formula of power
P = τ ω
ω = 2 π f
(a) f = 2500 rpm = 2500 / 60 = 41.67 rps
So, 40 x 1000 = τ x 2 x 3.14 x 41.67
τ = 152.85 Nm
(b) f = 250 rpm = 250 / 60 = 4.167 rps
So, 40 x 1000 = τ x 2 x 3.14 x 4.167
τ = 1528.5 Nm
Answer:
Due to the Electric Charge Conservation Law, the statement is <u><em>true.</em></u>
Explanation:
Conservation laws state that the physical properties or magnitudes of a given system have a constant value, that is, they cannot change.
Electric charge is a property that exists in some subatomic particles, manifested by attractions and repulsions that give rise to electromagnetic interactions.
The electric charge is governed by the principle of conservation of the charge. This law establishes that the total load in an isolated system is constant, that is, it is not possible to create or destroy isolated loads. That is, they can only be moved from one body to another or from one place to another inside the given body.
As mentioned, this law is only valid for closed systems in which no charged particles enter or leave outside. Then it is concluded that the algebraic sum of the charges of all particles remains constant.
Finally, <u><em>due to the Electric Charge Conservation Law, the statement is true.</em></u>
