Answer:
the intensity of the sound waves produced by one 60-w speaker at a distance of 1.0 m is 60 w/m²
Explanation:
Intensity of sound , I, is given as;
I = P/A
Where;
P is the power through an area = 60-w
A is the area = ?
A = 1.0m × 1.0m = 1.0 m²
I = 60-w / 1.0 m²
I = 60 w/m²
Therefore, the intensity of the sound waves produced by one 60-w speaker at a distance of 1.0 m is 60 w/m²
A.) wet 21° Celcius, dry 27° Celcius
Electrostatic (it’s a combined word) that’s all what i know honestly, hope it helps:)
Answer:
False
Explanation:
Heat capacity;
The ability of absorbing the heat is know as heat capacity of the substance.In other words we can say that the ability to retain the heat without changing its temperature is known as heat capacity.
The specific heat of water (liquid) is 4.1813 KJ/kgK andf the specific heat of ammonia (liquid) is 4.7 KJ/kgK.
So we can say that the above given statement is False.
Therefore answer is --
False
Answer:
E. All of the answers are correct
Explanation:
Overload principle in fitness training is associated with a gradual development of an athlete's abilities by progressively increasing the athlete's load and training.
In order to do this, the athlete's limit must be surpassed albeit gradually at first then picked up later over time.
