Given the diagram provided, we can confirm that the object will accelerate in a downward direction.
<h3>Why will it accelerate downwards?</h3>
The free-body diagram shows us the forces that are acting on this object. Through this diagram, we can see that the forces on the left and right of the object are balanced, meaning that there will not have movement in either of these directions.
The diagram shows that the downward force being applied is not balanced by an opposite force, so the object will accelerate in this direction.
Therefore, we can confirm that object will accelerate in a downward direction due to its downward force not being balanced by an opposing force.

Answer:
30%
Explanation:
Efficiency = useful work / heat absorbed x 100
= 120/400 x 100
= 0.3 x 100
= 30%

Position displacement velocity acceleration are vectors and the rest are scalars
Answer:
0.117 m
Explanation:
First of all, we can find the wavelength of the wave in the problem, by using the wave equation:
where:
v = 350 m/s is the speed of the wave
f = 500 Hz is the frequency of the wave
is the wavelength
Solving for ,
This means that the distance between two consecutive points of the wave having a difference of phase of
is 0.7 m.
Here we want to find the distance between two points that have a difference of phase of
So, we can set up the following rule of three:
where d' is the distance we are looking for. Solving for d',
