Answer:
= F Δt / m
Explanation:
The impulse theorem and momentum is
I = Δp
F Δt = m
- m v₀
Before touching the ball is without movement, the force is represented by the kinetic energy of the club when it reaches the bottom of the path, so if this force is constant, the time [or the duration of the blow is directly proportional to the speed that the ball acquires.
= F Δt / m
The higher this speed, the greater the distance traveled.

The variable is the disinfectant that is used, because there different ones being used
Answer:
The water level will drop by about 1.24 cm in 1 day.
Explanation:
Here Mass flux of water vapour is given as

where
is the mass flux of the water which is to be calculated.
- D is diffusion coefficient which is given as

- l is the thickness of the film which is 0.15 cm thick.
is given as

In this
is the saturated water pressure, which is look up from the saturated water property at 20°C and 0.5 saturation given as 2.34 Pa
is the air pressure which is given as 0.5 times of 
- R is the universal gas constant as

- T is the temperature in Kelvin scale which is

By substituting values in the equation

Converting
into 
As 1 mole of water 18
so

Putting this in the equation of mass flux equation gives

For calculation of water level drop in a day, converting mass flux as

So the water level will drop by about 1.24 cm in 1 day.
