Answer:
The frequency of the wave is 5.0Hz
Explanation:
The frequency of a wave is the number of oscillations or revolutions made in a second.
Just took the test and D: Standing Wave is the answer! :)
Answer: 100 J
Explanation: 1/2 5 x 2^2 = 100
Hope this made any sense.
Time = (distance) / (speed)
Time = (150 x 10⁹ m) / (3 x 10⁸ m/s) =
50 x 10¹ sec =
<em>500 sec</em> = 8 min 20 sec
For the potential energy is converted to kinetic energy is mathematically given as
n=24.44%
<h3>What efficiency of the potential energy is converted to kinetic energy?</h3>
Generally, the equation for the potential energy is mathematically given as
Ei=mgh
Ei=49.0\*9.81* 1.8
Ei=865.24J
Final total energy
K.E=0.5mv^2
K.E=0.5*49.0* (3.00)^2
K.E=211.5J
In conclusion, efficiency
n=Ef/Ei*100
n=211.5*865.24*100
n=24.44%
