Answer:
Speed, v = 312.34 m/s
Explanation:
The equation that describes a transverse wave on the string is given by :
..............(1)
Where
y = displacement of a string particle
x = position of the particle on the string
The wave is travelling in the +x direction. We have to find the speed of the wave.
The general equation of traverse wave is given by :
................(2)
On comparing equation (1) and (2) we get,
k = 3 rad/m
Since, 
..............(3)
Also, 
Since, 
...............(4)
Speed of the wave is the product of frequency and wavelength i.e.

Using equation (3) and (4), the speed of the wave can be calculated as :

v = 312.34 m/s
Hence, the speed of the transverse wave is 312.34 m/s
Yes, It does require some math skills.
Answer:0.967meV
Explanation:
-Find the difference in u, so 130.906118-130.90508= 0.001038u
- convert to meV
1 u = 931.494meV
multiply 0.001038 by 931.494
=0.001038 X 931.494
0.967 meV
450 J / 3 s = 150 J/s = 150 watts.
