Answer:
C) Gravitational potential energy
Explanation:
As ball is thrown upwards then we can say that speed of the ball will decrease as it will move upwards.
This is due to gravity which act opposite to the motion of the ball
So as the ball is thrown upwards the initial kinetic energy of the ball will start decreasing as it will move upwards
Here we also know that gravitational potential energy of the ball is given as
so as the ball start rising upwards the potential energy of the ball will increase
so here correct answer will be
C) Gravitational potential energy

Answer:
a) 9.72 mm
b) 4.86 mm
Explanation:
wave length of light λ is 580 nm = 580 \times 10⁻⁹ m
Width of slit d = 0.215\times 10⁻³ m
Distance of screen D = 1.8 m.
Width of one fringe =
Putting the values we get fringe width
=
=4.86 mm.
a) Width of central maxima = 2 times width of one fringe
= 2 times 4.86
=9.72 mm
b) width of each fringe except central fringe is same , no matter what the order is.Only brightness changes .
So width of either of the two first order bright fringe will be same and it will be
= 4.86 mm.
