Answer:

Explanation:
Assuming the light takes essentially no time to reach you, the distance at which the lightning occurred can be calculated by multiplying the speed of sound by the time it takes to hear the thunder:

You multiply the high length and width and if your using centimeters then divide by 500 and then there's your answer.hoped this helped.
Answer:
50.4÷1.18= 42.7m/s as speed is equal to the distance over the time taken
Answer:
-3.63 degree Celsius
Explanation:
We are given that
Boiling point of solution=
C
Boiling point water=100 degree Celsius



Where
=Boiling point of solution
Boiling point of pure solvent
C

Using the formula

Molality,
m

Using the formula


We know that

Where
=Freezing point of solvent
Freezing point of solution
Using the formula

Freezing point of water=0 degree Celsius

Hence, the freezing point of solution=-3.63 degree Celsius
