Answer:
A sound wave is called a longitudinal wave because compressions and rarefactions in the air produce it. The air particles vibrate parallel to the direction of propagation.
There's no maximum age that a human can have it all depends on your health if your a healthy person you can live for a long time but if you just feed your body junk and don't properly take good care of it then you can die at a young age.
Answer:
54%
Explanation:
So, we have that the "magnitude of its displacement from equilibrium is greater than (0.66)A—''. Thus, the first step to take in answering this question is to write out the equation showing the displacement in simple harmonic motion which is = A cos w×t.
Therefore, we will have two instances t the displacement that is to say at a point 2π/w - a2 and the second point at a = a2.
Let us say that 2π/w = A, then, we have that a = A cos ^-1 (0.66)/2π. Also, we have that a2 = A/2 - A cos^- (0.66) / 2π.
The next thing to do is to calculate or determine the total length of of the required time. Thus, the total length is given as:
2a1 + ( A - 2a2) = 2A{ cos^-1 (0.66)}/ π.
Therefore, the total percentage of the period does the mass lie in these regions = 100 × {2a1 + ( A - 2a2) }/A = 2 { cos^-1 (0.66)}/ π × 100 = 54%.
Thus, the total percentage of the period does the mass lie in these regions = 54%.
Light bulbs, think about parallel circuits as something you plug into, so for example you plug in a tv for it to work, same with a refrigerator and Christmas lights
Answer:
0.176 m/s
Explanation:
given,
mass of the puck, m = 170 g
Length of the ramp, L = 3.6 mm
angle of inclination, θ = 26°
the minimum speed require to reach at the top of the ramp
using equation of motion
v² = u² + 2 a s
final speed of the puck is zero
0² = u² - 2 g s
height of the pluck
h = 1.58 mm
h = 0.00158 m
now,
u = 0.176 m/s
hence, the speed required by the pluck to reach at the top is equal to 0.176 m/s
