Answer:
Explanation:
I can use insulated materials to cover the doors, windows and floors or I use quilted blankets to cover the doors, windows and the floor, this will reduce the sound coming in the room and the sound escaping out of the room.
I can possibly use carpet or floor mats on the floor, especially in front of the door to cover the crack that may be underneath it.
By definition, the mechanical advantage is the relationship that exists between the output force or load lifted and the value of the force applied.
Thus, using the definition, we have that the mechanical advantage is given by:
Therefore, the mechanical advantage of lifting the box by using a pulley is equal to 1.
Answer:
The mechanical advantage in this situation is:
Equal to 1

Answer: False</h2>
Explanation:
Acceleration is defined as the variation of Velocity in time :
A body also has acceleration when it changes its direction. However, the rate or variation of position with time <u>is not</u> acceleration, is the definition of velocity.
Therefore the sentence is false.
Gravitational potential energy = mass x gravitational field strength (g) x height
The box accelerates at 1. 0 m/s² to the right because the net force is 17N to the right . This statement clearly depicts the relation between force and acceleration. Hence option A is correct.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec².It is a vector quantity. It requires both magnitudes as well as direction to define.
According to Newton's second law of motion, the net force acting on the body is equal to the product of mass and acceleration of the body.
The direction of acceleration is in the direction of net force acted.
Hence option A is correct.
