Answer:
where is volume? formula of density is: mass/volume so volume must be there
Answer: false.
Explanation:
Doppler effect is caused to the relative motion of the source of light/sound with respect to the observer.
If the source is moving towards you, you will perceive the frequency to be larger (also called a blue shift), while if the wave is moving away, you will perceive the frequency to be smaller (also called a red shift).
Then the statement:
"Doppler effect is caused by sound or light wave being pushed together and spread apart due to motion."
Is false
The term metabolic syndrome defines a group of risk factors which determine your risk for health issues such as heart disease, a stroke and diabetes. Abdominal weight gain (a), elevated blood fat (c) and insulin resistance (d) are all characteristics which will increase your risk of the above health issues. The only characteristic that will decrease your risk of heart disease, diabetes and a stroke is reduced blood pressure (b). If you have any of these negative characteristics, it is important to work at reducing them; thereby, improving your health.
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
=
+
+
where
= 10*100 W =1 KW
= 40*360 KJ/h= 4 KW
=15000KJ/h= 4.17 KW
= 1+4+4.17=9.17 KW
the number of air conditioner unit is =
=1.83
which is approximately 2 units
