Answer:
Incomplete question: The masses of the blocks m₂ = 1.5 kg and m₃ = 2 kg
Explanation:
Given data:
L₁ = length = 0.85 m
L₂ = 0.25 m
L₃ = 0.5 m
m₂ = 1.5 kg
m₃ = 2 kg
Question: Find the unknown mass of the block 1 needed to balance the bar, m₁ = ?
The torque is zero (intermediate point of the bar)
Is negative because mass 1 is to the left of the coordinate system (see the diagram)
The net force is determined is basically who is pushing harder in a specific direction.Like since there bith pushing in the same direction the net force is in the direction that they are pushing.
2 pounds because 2.0X1.5 m is 2 when rounded up
Beats can be defined as the periodic fluctuations in the frequency of sound waves. That is option D
<h3>What are sound waves?</h3>
Sound waves are those waves that are produced by the vibration of an object whose energy is usually propagated through a medium.
When two sound waves of different frequencies meets, a periodic variation that occurs is called beats.
Therefore, Beats can be defined as the periodic fluctuations in the frequency of sound waves.
