Question 5- A gas occupies 60 liters at a pressure of 40.0 mm Hg. What is the volume when the pressure is
increased to 60.0 mm Hg?
60L
.666L
40L
100L

40L

Explanation:

Data obtained from the question include:

V1 (initial volume) = 60L

P1 (initial pressure) = 40mmHg

V2 (final volume) =?

P2 (final pressure) = 60mmHg

Using P1V1 = P2V2, the final volume can be obtain as illustrated below:

P1V1 = P2V2

40 x 60 = 60 x V2

Divide both side by 60

V2 = (40 x 60)/60

V2 = 40L

Therefore, the final volume is 40L

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

so easy. just google the electromagnetic waves and it’ll pop up.
