<h3><u>Answer;</u></h3>

A:The wave travels faster and with the same wavelength.

<h3><u>Explanation;</u></h3>
  • <em><u>Sound waves are mechanical waves which require a material medium for transmission. </u></em>
  • The transmission of sound waves involves the vibration of particles of the material medium thus movement of energy from one point to another.
  • <em><u>Sound waves entering a warmer air means that the kinetic energy of the air particles will increase and thus the vibration of particles will be increased and thus the speed of transmission of sound waves increases. </u></em>

The answer is A........The sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air are greater.

The Earth can be approximated as a sphere of uniform density, rotating on its axis once a day. The mass of the Earth is 5.97×102
svetlana [45]

Answer:

I = 97.2 10³⁶ kg m²

Explanation:

The moment of inertia of a body the expression of inertia in the rotational movement and is described by the expression

      I = ∫ r² dm

In this problem we are told to use the moment of inertia of a uniform sphere, the expression of this moment of inertia is

     I = 2/5 M r²

where m is the mass of the earth and r is the radius of the earth.

Let's calculate

      I = 2/5  5.97 10²⁴ (6.38 10⁶)²

      I = 97.2 10³⁶ kg m²

How does the digestive system interact with the following organ systems (circulatory, muscular and nervous system) to maintain h
Lemur [1.5K]

Answer:

The circulatory system breaks down food and gets / absorbs nutrients. The muscular system works to get nutrients to the rest of the body. The nervous system basically controls the digestive system and sends information to the brain.

I'm pretty sure I'm right, but please correct me if I'm wrong! :)

A classroom that normally contains 40 people is to be airconditioned with window air-conditioning units of 5-kW cooling capacity
oksano4ka [1.4K]

Answer:

About  2 units.

Explanation:

We assume that there is no heat dissipating instrument in the room

Total cooling load of the room is defined from the given below equation

Q_{cooling}=Q_{light}+Q_{people}+Q_{heat gain}

where

Q_{light}= 10*100 W =1 KW

Q_{people} = 40*360 KJ/h= 4 KW

Q_{heat gain}=15000KJ/h= 4.17 KW

Q_{cooling}= 1+4+4.17=9.17 KW

the number of air conditioner unit is =\frac{9.17}{5}=1.83

 which is approximately 2 units
