Beats are generated by two interfering waves when they have slightly different frequencies.
<u>Answer
</u>
He should make the arrow for “Path” curve downward.
<u>Explanation
</u>
The force of gravity is usually directly downward. So from the diagram, it is correctly labelled.
If the object was given a horizontal force, the direction of the inertial is also correct. Inertial is the force the resist the change of state of motion.
What Hector should change is the path followed by the object. It will be a curve not a straight line as it is drawn.
The correct answer is He should make the arrow for “Path” curve downward.
I'm not sure of the numbers sense I dont have a calculator right now. The formula is 1/2*M*V^2.
Explanation:
Calculating acceleration is complicated if both speed and direction are changing or if you want to know acceleration at any given instant in time. However, it’s relatively easy to calculate average acceleration over a period of time when only speed is changing. Then acceleration is the change in velocity (represented by Δv) divided by the change in time (represented by Δt):
acceleration=ΔvΔt
Explanation:
The cross section per unit length is uniform, so ρ is constant.
The center of mass is therefore:
x_avg = (∫₀ᴸ x ρ dL) / (∫₀ᴸ ρ dL)
x_avg = (∫₀ᴸ x dL) / (∫₀ᴸ dL)
x_avg = (½ L²) / (L)
x_avg = ½ L
