For harmer:-
initial velocity=u=0m/s
Acceleration due to gravity=10m/s^2
Now



For soft drink:-
u=24m/s

Using eq(1)




After 1.2s they will meet.
Now
putting t in eq(1)

At the height of 7.2m they will meet
I believe the correct answer is B
The rate of doing work is called POWER.
Power is also defined as the rate of transfer of energy. It measures the speed of how work is done.
The unit of power is WATT.
Power is computed by dividing WORK DONE by TIME TAKEN.
P = W/t
1 watt:
*power of a machine
*power of an agent that does work at the rate of 1 joule per secon
1000 watt = 1 kilowatt
1000 kilowatt = 1 megawatt
Answer:
D) surface area of the water
Explanation:
The pressure at the bottom of a column of fluid is given by Stevino's law:

where
p is the pressure at the bottom of the column
is the density
g is the acceleration due to gravity
h is the depth of the liquid
So, we see that the pressure at the bottom of a jug filled with water depends on all these quantities:
A) depth of the liquid
B) acceleration due to gravity
C) density of water
While it does not depend on:
D) surface area of the water
The repeated rising and sinking of water during boiling is due to convection. It <span>is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Hope this answers the question.</span>
