Answer:
The answer is the kinetic energy of sled B after it crash is 6439j.
Transverse wave as the wave is going up and down no compressions
Answer:
Explanation:
In case of diffraction , angular width of central maxima =2 λ/d
λ is wave length of light and d is slit width
In case of interference , angular width of each fringe
= λ /D
D is distance between two slits
No of interference fringe in central diffraction fringe
=2 λ/d x D/λ = 2 x D /d = 2 x .24/.03 = 16.
C . Record the time to complete a chemical reaction
