Answer:
Explanation:
Let m is the mass of both cars. The first car is moving with speed v and the other car is moving with speed 2v. The only force acting on both cars is the centripetal force.
For faster car on the road,
v = 2v
..........(1)
For the slower car on the road,
............(2)
Equation (1) becomes,
So, the frictional force required to keep the slower car on the road without skidding is one fourth of the faster car.
The index of refraction of a material is the ratio between the speed of light in vacuum, c, and the speed of light in that material, v:
where the speed of light in vacuum is
. The speed of light in benzene is 
, so we can use the previous relationship to find the refractive index of benzene:
where the speed of light in vacuum is
Answer:
Total distance does the grasshopper travel before the cars hit is 150 m
Explanation:
Each car moves x=100 m before they collide. Both the cars moving in constant velocity. time taken t by each car is
where x is the distance traveled with velocity v
The insect is moving through this time period with a constant velocity of 15 m/s
The distance traveled by grasshopper is
