The answer is B because, the farther the goes the speed starts to decrease and stops it depends on the frequency of the wave.
Answer:
Explanation:
Laminar Flow is a very important topic discussed in physics in the subject of fluid dynamics. Basically, it explains how fluid particles behave at lower velocities. In such cases and when the viscosity of the fluid is low, the fluid particles flow smoothly in perfectly perpendicular layers that do not collide or cross each other. Unlike turbulent flow, which is the opposite. An example of Laminar flow can be seen when you open up a water hose with little pressure, the water simply flows out of the hose and looks very clear and smooth.
Answer: 2 m/s^2
Explain
£F=ma
net force = mass x acceleration
4N is a force acting on it
4N=(2kg) a
2kg is the mass
you divide the 2 over
and A= 2 m/s^2
Explanation:
Since it is mentioned that the block is in equilibrium, this means the resultant force is zero, and all the forces cancel out each other.
You have to think it in a way so that, the forward force cancel out the backward force. Check the picture attached, on the forward side,
3N + 5N = 8N which cancel out the backward force of 8N
