Juan is standing on the street. An ambulance moves toward him and then passes by. What best describes the pitch that Juan hears?

The pitch remains constant as the ambulance moves toward and then away from Juan. The pitch increases and decreases in a repeated pattern as the ambulance passes Juan. The pitch drops to a lower pitch once the ambulance passes by Juan. The pitch increases to a higher pitch once the ambulance passes by Juan.

Answer: The correct answer is "the pitch drops to a lower pitch once the ambulance passes by Juan".

Explanation:

Doppler effect is the phenomenon in which there is an increase or decrease in the frequency when there is relative motion between the source and listener.

Pitch depends on the frequency. if the frequency increases then pitch increases.

When the source and the listener are moving towards each other then there is increase in the frequency. When the source and the listener are moving away each other then there is decrease in the frequency.

In the given problem, Juan is standing on the street. An ambulance moves toward him and then passes by the pitch drops to a lower pitch once the ambulance passes by Juan.

Determine the values of m and n when the following mass of the Earth is written in scientific notation: 5,970,000,000,000,000,00
yuradex [85]

Explanation:

Mass of the Earth is equal to,

m=5,970,000,000,000,000,000,000,000\ kg

Any number can be written in the form of scientific notation as :

N=m\times 10^n

m is the real number

n is any integer

Mass of the earth can be written in the form of scientific notation as :

m=5.97\times 10^{24}\ m

Here,

m = 5.97

n = 24

Hence, this is the required solution.

What results when energy is transformed while juggling three bowling pins?
Nady [450]

Answer:

his is an example of the transformation of gravitational potential energy into kinetic energy

Explanation:

The game of juggling bowling is a clear example of the conservation of mechanical energy,

when the bolus is in the upper part of the path mechanical energy is potential energy; As this energy descends, it becomes kinetic energy where the lowest part of the trajectory, just before touching the hand, is totally kinetic.

At the moment of touching the hand, a relationship is applied that reverses the value of the speed, that is, now it is ascending and the cycle repeats.

Therefore this is an example of the transformation of gravitational potential energy into kinetic energy

Which statements accurately describe mechanical waves? Check all that apply.
stiks02 [169]

Answers that apply include

  • Energy is transferred through vibrating particles
  • An ocean wave moving through water is an example of a mechanical wave
  • A longitudinal wave is a type of mechanical wave.
  • A transverse wave is a type of mechanical wave

Mechanical waves can't pass through vacuum like electromagnetic waves because t depends on the transfer of energy between particles of matter (matter that has inertia and elasticity). This energy propagates in the same direction as the wave. Another example of mechanical energy is sound. In addition to longitudinal and transverse waves, another type of mechanical wave is surface waves.
