The catalyst lowers the activation energy.
You've described two (2) axes of motion.
The third one would have been up-and-down.
speed of the car is given on the road

reaction time is given as

now we can find the distance that it will move during this reaction time

now the deceleration of the car is 10 m/s^2
so the distance that it will move before stop is given by



so the total distance that it require to stop is given as

while the deer is standing at distance 38 m
so the car will stop 2.8 m before the position of deer
Answer:
R1 + R2 = R = 12 for resistors in series - so R1 = R2 if they are identical
2 R1 = 12 and R1 = R2 = 6 ohms
1 / R = 1 / R1 + 1 / R2 for resistors in parallel
R = R1 * R2 / (R1 + R2) = 6 * 6 / (6 + 6) = 3
The equivalent resistance would be 3 ohms if connected in parallel
Velocity ratio is also defined as the ratio of a distance through which any part of a machine moves, to that which the driving part moves during the same time. An object has a mechanical advantage if it exerts a force higher than the velocity ratio.
