The easiest way to answer this question is by realizing there are relating the velocities of the two cars. To tackle this problem, you have to understand the picture. Car 1 travels at 35m/s and Car 2 travels at 25m/s. Based on relative velocities, we can understand that Car 1 travels 10m/s faster than Car 2 every second. So we can interpret Car 1's relative velocity to Car 2 as 10m/s. Car 1 needs to travel 10m/s till a point of catching up to Car 2 which is 462m away.
v = 10m/s
d = 462m
v = d/t
(10) = (462)/t
t = 46.2s
So it takes 46.2 seconds for Car 1 to catch up to Car 2, but the question is asking how far does Car 1 travel to catch up. So we have to use Car 1's velocity and not the relative velocity:
v = 35m/s
v = d/t
(35) = d/(46.2)
d = 1617m
Car 1 traveled a total distance of 1617m.
-- You are 462 meters behind.
-- You're gaining on him at the rate of (35m/s - 25m/s)= 10 m/s.
-- At that rate, it'll take you (462m / 10m/s)= 46.2 seconds to over take him.
-- During that time, you'll cover (46.2s x 35m/s)= 1,617 meters.
Answer:
Carbon monoxide is produced when combustion reactions are not fully completed,either through lack of oxygen or due to low mixing.
Carbon monoxide is a colorless and odorless gas.
of that energy is used to actually move the car? Record your answer in
kilojoules.
The reason that the sun changes colors at sunset is because small particles and molecules in the atmosphere change the direction of light ray causing them to scatter and resulting in a beautiful sunset.
B) boiling point, volume
C) flammability, volume
D) melting point, reactivity with water
Plz answer this question quickly, it’s really important
I believe the correct answer is D. melting point, reactivity with water.
1 and 2 only

If Linh removes bulb 3,the bulbs which will remain lit are 1, 2 and 4.
The electric circuit provided with battery creating potential difference across resistance or capacitor or inductors.
When Linh removes the middle branch, the bulbs 1, 2 and 4 will be acting as resistor which are in series connection. The current flow will be same in all the resistors except 3.
Thus, If Linh removes bulb 3, the bulbs which will remain lit are 1, 2 and 4.
