Answer:
The roaring of the lion is louder and has low pitch than the sound produced by a mosquito. Hence, they sound so different
A saw, because wheels and or axles are present in all of the other items. A saw is a wedge, this it does not contain axles or wheels.
A) We differentiate the expression for velocity to obtain an expression for acceleration:
v(t) = 1 - sin(2πt)
dv/dt = -2πcos(2πt)
a = -2πcos(2πt)
b) Any value of t can be plugged in as long as it is greater than or equal to 0.
c) we integrate the expression of velocity to find an expression for displacement:
∫v(t) dt = ∫ 1 - sin(2πt) dt
x(t) = t + cos(2πt)/2π + c
x(0) = 0
0 = = + cos(0)/2π + c
c = -1/2π
x(t) = t + cos(2πt)/2π -1/2π
Answer:
Explanation:
<em>Waves is defined as a disturbance that travels through a </em><em>medium</em><em> and transfers energy from one point to another without causing </em><em>any permanent displacement of the medium</em><em> itself.
</em>
Longitudinal waves and transverse waves are types of progressive waves and their difference depends on the direction of the vibrating medium and the wave generated by the medium.
Longitudinal waves are generated when the vibration of the medium is <em>parallel</em> to the direction of wave generated while transverse waves are waves generated when the vibration of a medium is to the direction of wave.
