1) 234 s, 6.18 km
The position of the car at time t is described as

where
is the velocity of the car
The position of the head of the train instead is given by

where
d = 1.30 km is the initial distance between the car and the head of the train
is the velocity of the train
The car overtakes the train when

Substituting and solving for t,

And the distance travelled by the car is

2) 27.5 s, 0.72 km
In this case, the train is travelling in opposite direction, so we can write

Again, we can use the same equation as before

And solving for t, we find

And the distance travelled by the car is

Answer:Sound travel faster in warm room.
Explanation:The speed of sound depends on the temperature of the medium. Mathematically, the relation between the speed of the sound and the temperature is give by:v=
is the ratio of the specific heats
R is the gas constant
T is the temperature of the medium
We know that the temperature of the warm room is more as compared to the cold room.
So, it is clear that the sound travel faster in a warm room. The particles move faster when the temperature is high.
Because at the time of New and Full moons, the Earth, Sun,
and Moon are all lined up on the same line. So the effects
of the Sun and Moon combine to influence the tides in the
same direction.
