Explain how the parts of a wave are affected by the changes in amplitude and pitch

Answers

Answer 1
Answer: waves propagating through material medium the amplitude of the waves decides the intensity of the waves as intensity is directly proportional to the square of its amplitude.

What is the property of water, powdered drink mix, and sugar after mixing

Answers

When all ingredients are mixed the 2 solids are dissolved into the water making it all liquid but the taste is still there. The drink mix gives it a little flavor and the sugar makes it sweet. The water is there to make it a liquid, it all turns out to be a colored liquid. Hope this helped! :)

100. mL of a gas are obtained from a reaction at 300.⁰C. What volume will the gas occupy at 100.⁰C?

Answers

Answer:

The new volume is 65.1 mL.  

Explanation:

We have,

Initial volume of the gas is 100 mL

Initial temperature is 300 degrees Celsius

It is required to find the volume the gas will occupy at 100 degrees Celsius. Charles law gives the relation between volume and temperature such that,

V\propto T

So,

(V_1)/(V_2)=(T_1)/(T_2)

V₂ is new volume

V_2=(V_1T_2)/(T_1)

V₁ = 100 mL

T₁ = 300 C = 573.15 K

T₂ = 100 C = 373.15 K

Plugging into formula we get :

V_2=(100* 373.15)/(573.15)\n\nV_2=65.1\ mL

So, the new volume is 65.1 mL.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 300J of energy to the room?Answer:____________ unit:_______

Answers

Answer:

300 J.

Explanation:

  • The first law of thermodynamics is the law that demonstrates the conservation of energy.
  • It states that the total energy of an isolated system can not be created or destroyed, but it may be transformed into another form.
  • The energy released to the room is 300 J.
  • So, according to the law of conversation of energy; the amount of heat removed from food inside of the refrigerator is 300 J.
