Answer:

The Correct Answer is C

Explanation:

The association between pitch and frequency.

  • The pitch of a sound you detect relies on the repetition of the sound wave.
  • A greater-frequency sound wave has a great pitch, and a lower-frequency sound wave has a lowering pitch.
  • The frequency of a sound wave is the number of fluctuations that happen per moment.
  • The pitch of a sound is a representation of how great or below the sound appears to a person.

A child is riding a merry-go-round that is turning at 7.18 rpm. If the child is standing 4.65 m from the center of the merry-go-
iVinArrow [24]

Answer:

B) 3.50 m/s

Explanation:

The linear velocity in a circular motion is defined as:

v=\omega r(1)

The angular frequency (\omega) is defined as 2π times the frequency and r is the radius, that is, the distance from the center of the circular motion.

\omega=2\pi f(2)

Replacing (2) in (1):

v=2\pi fr

We have to convert the frequency to Hz:

7.18rpm*\frac{1Hz}{60rpm}=0.12Hz

Finally, we calculate how fast is the child moving:

v=2\pi(0.12Hz)(4.65m)\\v=3.5\frac{m}{s}

We can calculate the force that the atmospheric pressure produces on a surface. Consider a living room that has a 4.0m×5.0m floo
qaws [65]

Answer:

Force, F=2.02\times 10^6\ N

Explanation:

It is given that,

Length of the room, l = 4 m

breadth of the room, b = 5 m

Height of the room, h = 3 m

Atmospheric pressure, P=1\ atm=101325\ Pa

We know that the force acting per unit area is called pressure exerted. Its formula is given by :

P=\dfrac{F}{A}

F=P\times l\times b

F=101325\times 4\times 5

F=2.02\times 10^6\ N

So, the total force on the floor due to the air above the surface is 2.02\times 10^6\ N. Hence, this is the required solution.
