Which best describes pitch?

Physics
1 answer:
kozerog [31]3 years ago
3 0

Answer:

B) the number of cycles per second perceived by the human ear

Explanation:

The best expression that describes pitch is that it is the number of cycles per second perceived by the human ear.

For a wave train, the number of cycles per second is frequency. Whereas the period is the amount of time taken for a longitudinal wave to produce one cycle.

The distance between two corresponding parts of a transverse wave is its wavelength.

  • A high pitch will correspond to a high frequency of waves perceived.
  • A low pitch corresponds to a low frequency of waves.

A 12 V automobile battery is connected to an electric starter motor. The current
krek1111 [17]

Answer: 3000\ W,\ 78,000\ J

Explanation:

Given

The voltage of the battery is V=12\ V

Current through the battery is I=250\ A

(a) Power is the product of voltage and current

Power dissipates is given by

P=VI\\P=12\times 250\\P=3000\ W

(b) Energy delivered

E=P\times t

E=3000\times 26\\E=78,000\ J

Which of the following must be true about an object for it to be in uniform circular motion? A.It must have zero centripetal acc
Grace [21]

In the previous section, we defined circular motion. The simplest case of circular motion is uniform circular motion, where an object travels a circular path at a constant speed. Note that, unlike speed, the linear velocity of an object in circular motion is constantly changing because it is always changing direction. We know from kinematics that acceleration is a change in velocity, either in magnitude or in direction or both. Therefore, an object undergoing uniform circular motion is always accelerating, even though the magnitude of its velocity is constant.

A meteorite strikes the Moon at the speed of 11 km/s. It has KE of 60,500,000 J. What will be its mass?
Vikentia [17]
KE=1/2 mv²
60,500,000 = 1/2 m ( 11,000 m/s )²
60,500,000= 1/2 ( 11,000 )² m
60,500,000= 60,500,000 x m
m= 60,500,000/60,500,000
m= 1 kg

Ksivusya [100]

As the distance from the Sun increases the time to orbit the Sun  increases. <em>(a)</em>

Examples:

-- Nearest planet to the sun: Mercury.  Time to orbit the sun: 88 days

-- 3rd planet from the sun:  Earth.  Time to orbit the sun: 1 year

-- 5th planet from the sun:  Jupiter.  Time to orbit the sun: 12 years

-- 9th closest object to the sun:  Pluto.  Time to orbit the sun: 248 years

Another pair of examples:

-- Object in a near Earth orbit:  International Space Station

Time to orbit the Earth:  90 minutes

-- Object in a far Earth orbit:  the Moon

Time to orbit the Earth:  27.3 days

The reason for all of this is:  Two things about orbits.

1).  The larger the orbit is, the farther the object has to travel around it.

2).  The farther out the object is, the slower it travels in its orbit.

This is simply the way gravity works.
