Answer:
Explanation:
Given that:
acoustic power (P)= 3.77 × 10⁵ W
Find the intensity of the sound at a distance of 46.1 m from the engine
The distance (i.e the radius) = 46.1 m
The relation can used to find the intensity of the sound from the engine.
Substituting our values, we have:
Answer:
See the explanation below
Explanation:
This problem can be better understood graphically, so in the attached image we will use a diagram of a positive displacement air pump.
We can see that when she pushes the plunger, we see that the volume decreases.
Answer:
0.135 ms⁻²
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma ⇒ a = F/m
where terms are in usual meaning
a = 125/925 = 0.135 ms⁻²
Answer:
The nervous system handles the stress response, which, if overworked, can eventually lead to diseases ranging from high blood pressure to diabetes.
