Answer:
1.67m
5m/s
Explanation:
Wavelength of the wave = 3m
Speed of the wave = 5m/s
The distance between crest and the adjacent trough of water waves is known as the wavelength of a wave.
To find the frequency ;
V = f∧
V is the speed of the wave
f is the frequency
∧ is the wavelength
Insert the parameters and find the frequency;
f = V/ ∧ = 5 / 3 = 1.67Hz
The rate at which the wave passed a given point is the speed of the wave and it is 5m/s
The intensity of sound is just like the force of gravity, the force between electric charges, and the intensity of light . . . they all DEcrease at the same rate that the SQUARE of the distance INcreases.
So if two people are watching or listening to the same source, and one intensity is 1/10 as intense as the other intensity, then the farther person must be √10 times as far from the source as the nearer person is.
√10 = 3.1622 ...
So the second guy is about <em>3.16 miles</em> from the fire truck.
Answer: is C
Expiation: you can find the answer on quizlet and it’s diverging mirror so the answer is C
Answer:
B)
D)
Explanation:
Carnot cycle ;
This is the ideal cycle for all type of heat engine.All the process in the Carnot cycle is reversible processes ( those process does not leave any effect on the system as well as surrounding when the process is reversed is known as reversible process).It have four process in which two process is constant temperature and other two is isentropic or we can say that reversible adiabatic.
In the two process(constant temperature) only heat interaction take places and other two process(adiabatic) only work interaction take places.
So the option B and D is incorrect for Carnot cycle.
The answer is 12 J
because you have to multiply the two together. hope it helps
