Answer:
kinematics explains the terms like acceleration, velocity, and position of the objects while in motion.
Some important parameters in kinematics are displacement, velocity, and time.

your welcome,can you give me the brainliest? plssss
thank me if it was correct for you too.
Answer:
magnification is - 159
objective distance is 3.85 cm
Explanation:
Given data
focal length f1 = 1.40 cm
focal length f2 = 2.20 cm
separated d = 19.6 cm
to find out
angular magnification and How far from the objective
solution
we know magnification formula that is
magnification = ( - L / f1 ) (D/f2)
here D = 25 cm put all value
magnification = ( - 19.6 / 1.40 ) (25/2.20)
magnification = - 159
and
now we apply lens formula
i/f = 1/q + 1/p
p = f2 = 2.20
so
q = f2 p / p -f2
q = 1.4(2.20) / ( 2.2 - 1.4 )
q = 3.85 cm
so objective distance is 3.85 cm
Answer:
Part a)
Part b)
Part C)
This is loss in terms of thermal energy due to collision with the floor
Explanation:
Part a)
Since we know that the ball rises up by 65% of initial height
so after first bounce it will lose 35% of its initial energy
so we will have
Energy Loss = 0.35 mgH[/tex]
Part b)
Energy of the ball after first bounce
energy of ball after 2nd Bounce
energy of the ball after 3rd bounce
Now we will have energy loss in fourth bounce given as
Part C)
This is loss in terms of thermal energy due to collision with the floor
