When you are traveling in your car at highway speed, the momentum of a bug is suddenly changed as it splatters into your windshi
makvit [3.9K]

Answer:

Answered

Explanation:

By the law of conservation of the momentum The car-bug system moment will  remain the same before and after the collision.  And since the mass of the car is much higher than the bug, the change in velocity of the car will be negligible as compared to the change in velocity of the bug and hence the change in momentum of the bug will be very large and change in momentum of the car will be negligible.

I = 5*10  - 7A

q = 5 *15*1-  - 7 cuolomb
= 75 *10 -7 C in 15 sec is indecent

1 proton has  q = 1.6 *10 - 19C

75 *10-7  / 16* 10-19

= 4.7 x 10^13

A wagon wheel consists of 8 spokes of uniform diamter, each of mass m, and length L. The outer ring has a mass m rin. What is th
Genrish500 [490]

Answer:

L^2(\dfrac{8m}{3}+m_r)

Explanation:

m = Mass of each rod

L = Length of rod = Radius of ring

m_r = Mass of ring

Moment of inertia of a spoke

\dfrac{mL^2}{3}

For 8 spokes

8\dfrac{mL^2}{3}

Moment of inertia of ring

m_rL^2

Total moment of inertia

8\dfrac{mL^2}{3}+m_rL^2\\\Rightarrow L^2(\dfrac{8m}{3}+m_r)

The moment of inertia of the wheel through an axis through the center and perpendicular to the plane of the ring is L^2(\dfrac{8m}{3}+m_r).
