<u>Answer:</u> The angle of diffraction is 0.498°
<u>Explanation:</u>
To calculate the angle of diffraction, we use the equation given by Bragg, which is:
where,
n = order of diffraction = 3
= wavelength of the light = 
(Conversion factor: 
)
d = spacing between the crystal planes = 0.100 mm = 
(Conversion factor: 1 m = 1000 mm)
= angle of diffraction = ?
Putting values in above equation:
Hence, the angle of diffraction is 0.498°
Answer:
is a field force, as gravity does not physically apply force and does not require proximity.
Explanation:
consider the motion of the tennis ball in downward direction
Y = vertical displacement = 400 m
a = acceleration = acceleration due to gravity = 9.8 m/s²
v₀ = initial velocity of the ball at the top of building = 10 m/s
v = final velocity of the ball when it hits the ground = ?
using the kinematics equation
v² = v²₀ + 2 a Y
inserting the values
v² = 10² + 2 (9.8) (400)
v = 89.11 m/s
