To calculate the speed of the water leaving we use the formula,
Here h is the height of the water above the hole and g is the acceleration due to gravity.
Given,
Substituting the given value in above formula we get
Thus, water flow from a hole at the speed is 10.7 m/s
If the temperature in the tank is decreased this would imply that the kinetic energy of molecule decreases because of the ideal gas law:
PV= nRT (Since Pressure is directly proportional to Temperature).
So the answer is B.The air pressure in the rigid tank decreases.
Hope this helps you.
Mass is number 2. Vector is 5. Force is 3. Weight is 1. Net force is 6. magnitude is 4.
Answer:
The Sun transforms nuclear energy into heat and light energy.
Our bodies convert chemical energy in our food into mechanical energy for us to move.
An electric fan transforms electrical energy into kinetic energy.
R because A-B has 7R but C-d only has 6r so you need to add another r
