Answer:
0.78333 m/s in the opposite direction
1.566 m/s in the same direction
Explanation:
= Mass of penny = 0.0025 kg
= Mass of nickel = 0.005 kg
= Initial Velocity of penny = 2.35 m/s
= Initial Velocity of nickel = 0 m/s
= Final Velocity of penny
= Final Velocity of nickel
As momentum and Energy is conserved


From the two equations we get

The final velocity of the penny is 0.78333 m/s in the opposite direction

The final velocity of the nickel is 1.566 m/s in the same direction
Answer:
The phase difference between waves 31.7 rad
Explanation:
Given :
Wavelength
m
Separation between two slit
m
Angle
25°
From the formula of phase difference,

Where
phase difference
