Answer:
160J
Explanation:
Given parameters:
Frequency = 16Hz
Wavelength = 10m
Unknown:
Waves speed = ?
Solution:
Waves speed is the product of frequency and wavelength;
Waves speed = fλ
f is the frequency
λ is the wavelength
Now insert the parameters and solve;
Waves speed = 16 x 10 = 160J
This is mr day and infact am seeing this… come into my office after class.
The answer is 138.75 kgm/s
Impulse (I) is the multiplication of force (F) and time interval (Δt): I = F · Δt
It is given:
m = 0.25
F = 18,500 N = 18,500 kgm/s²
Δt = 0.0075 s
I = ?
I = F · Δt = 18,500 5kgm/s² * 0.0075 s = 18,500 * 0.0075 kgm/s² * s = 138.75 kgm/s
The chemical bonds alow it to pass to the other object.
Answer: (Next time put the Image but I know what u talkin bout)
wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
Explanation:
When wave travels from one medium to other medium the due to change in the speed of the wave propagation it deviates from its initial path.
The deviation of the wave from its initial path is known as refraction of wave
Here we can see that wave incident on medium 1 with some angle with the boundary
Then it enters into other medium and then travels in other direction
So here wave changes its path from its initial direction so this phenomenon is known as Refraction of wave
