- 1. The value of m is 3.735
2. The value of n is 7
<h3>What is momentum? </h3>
Momentum is defined as the product of mass and velocity. It is expressed as
Momentum = mass × velocity
<h3>How to determine the value of m and n</h3>
We can obtain the value of m and n by simply obtaining the momentum in scientific notation. This is illustrated below:
- Mass of train = 4.5×10⁵ Kg
- Velocity of train = 8.3×10¹ m/s
- Momentum =?
Momentum = mass × velocity
Momentum = 4.5×10⁵ × 8.3×10¹
Momentum = 3.735×10⁷ Kg⋅m/s
Thus, the value of m and n are: 3.735 and 7

Answer:
This point is not accelerating.
Explanation:
An object can be acted on by several forces at the same time, these forces are vector quantities (with magnitude and direction associated). The vector sum of all of the forces acting on a body is a single force called the net force when an object is in equilibrium this net force is equal to zero.
<em>According to Newton's second law of motion, the acceleration of an object as produced by a net force is directly proportional to the net's force, direction, and force and inversely proportional to the mass of the object. </em><em>This means that if the net force is zero an object will have zero acceleration.</em>
Therefore we can conclude that the sum of the three forces acting on the center point of the rope is assumed to be zero this point is not accelerating.

Answer:
* energy is proportional to masses. in a graph it would look like a line
* kinetic energy varies with the square of the velocity, In a graph it gives rise to a quadratic curve
Explanation:
Kinetic energy is defined by
K = ½ m v²
when analyzing this expression we can see:
* energy is proportional to masses. Therefore, doubling the mass doubles the kinetic energy and if the mass rises 4 times the energy rises 4 times, that is, they are directly proportional, in a graph it would look like a line
* kinetic energy varies with the square of the velocity. Therefore by doubling the speed the energy goes up 4 times. In a graph it gives rise to a quadratic curve
The answer is A. Because if you're increasing the power than the strength will increase.
