In a bath, a plane wave propagates from the shallow part towards the suddenly deep part. As it passes the interface from shallow to deep, it refracts. The angle of incidence is 22º, the angle of refraction 31º. a) In which part is the speed of sound greater and by how many percent? b) Calculate the wavelength in the shallow part if it is 5.5 cm in the deeper part!
If you could explain in detail itd be great!
The period of a mass-on-spring oscillator is 3 seconds. Upon decreasing its mass by 500 g, the period will become 2 seconds.
a) Calculate the original mass!
b) Calculate the spring constant!
Could you please explain in detail how to use the equation below?
"T=2\\pi\u221am\/k"
A ball (m=0.8 kg) falls to the floor from a height of 2 m and bounces back to a height of 1.2 m. Calculate the amount of energy lost due to air drag and collision with the ground.

15. A body projected upward from the level ground at certain angle, if the total time taken is 6.3sec with an initial velocity of 40m/s. Find (i) (ii) (iii) (iv) The angle of projection How far from the starting point will it strike the ground How height will it go Max. Range
A heavy block is suspended from a vertical spring.
The elastic potential energy is stored in the spring is 4 J.
What is the spring constant if the elongation of the spring is 10 cm?
3.7. Show that: If a particle is subject to a central force only, then its angular momentum is conserved i.e. If V(r) = V(r), then dL/dt = 0.
