Answer:
The frequency of wave is 4.34 Hz.
Explanation:
We know the relation:
λ = = × ........................................1
where,
λ= wavelength
v= velocity of wave
T= Period of wave
By the definition of period T, you are given that HALF of T is 0.115 s, so
T = 2 × (0.115 s)
= 0.23 s
Then,
λ = v × T
= (7.33 m/s) × (0.23 s)
≅ 1.686 m
Now for frequency, return to equation 1,
=
=
= 4.34
The frequency of the wave is calculated as 4.34 Hz.
Answer:
0.230
Explanation:
That's the answer, the one above isn't, I got this answer correct on acellus
Answer:
True........................
Yes, it has a speed and a direction, and that makes a velocity. So it's True.
Answer:
V=Volts
I= Amperes
R= Ohms
Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning)
Change in speed = (54 km/hr) - (32 km/hr) = 22 km/hr
Acceleration = (22 km/hr) divided by (the time it takes to change the speed)
Yes, a heat pump moves heat.
No, heat is not created.
No, the heat supplied does not create a large enough temperature difference.
No,we cannot use heat pump to provide the temperature difference to run a heat engine.
Explanation:
In a heat pump energy is transferred from the heat source to the heat sink whereas in the heat engine energy is transferred from a higher temperature level to a lower temperature level called sink.In a heat engine the heat energy is converted into mechanical energy
