Which of the following can be accurately determined using newtonian physics? a. the speed of an object moving at nearly the speed of light b. the momentum of a car c. the position of an electron d. the length of an object moving at nearly the speed of light

B.The momentum of a car

Explanation:

Here we know that Newtonian physics is also known as classical physics because here we assume that all the moving particles are at finite speed which is very small as compare to the speed of light

So main concept of classical physics is that the speed is always smaller then the speed of light.

So here we have correct answer as

B.The momentum of a car

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
