Answer:
Plane spacing,
Explanation:
It is given that,
Wavelength of x-ray,
Angle the x-ray made with a set of planes in a crystal causing first order constructive interference is 30 degrees
We need to find the plane spacing. It is based on Bragg's law such that,
d is plane spacing
n = 1 here
So, the plane spacing is .
Answer:
Force=mass×acceleration.
4:5 for masses , 2:3 for acceleration.
For the first car it will be 4×2=8N
For the second car it will be 5×3=15N
Increase in wavelength will cause decrease in frequency. When wavelength doubles, the frequency of the wave will reduce to half of its value.
<h3>
WAVE SPEED</h3>
The wave speed is the product of wave frequency and its wavelength.
v = f⋅λ
For example, if a wave has a frequency of 120 Hz and a wavelength of 5m, it would have a speed of 600 m/s.
if the wavelength is increased to 10m but the speed stays the same at 600 m/s. That is,
λ = 10m
v = 600 m/s
v = f⋅λ
Substitute f and v into the formula
600 = 10f
f = 600 / 10
f = 60 m
The frequency of the wave is reduced to half of its value.

There are three ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
