The relative density of the battery decreases when the battery is turned from charging to discharging position.
The relative density of the charged battery is mostly 1.28 to 1.3 and the relative density of the discharged battery is 1.15.
Thus, option C is more appropriate for the given case.
Answer:
The pressure at this point is 0.875 mPa
Explanation:
Given that,
Flow energy = 124 L/min
Boundary to system P= 108.5 kJ/min
We need to calculate the pressure at this point
Using formula of pressure
Here,
Where, v = velocity
Put the value into the formula
Hence, The pressure at this point is 0.875 mPa
Answer: A- The technology or tools available to test scientific claims. I just took this test and passed.
Answer: A sealed calorimeter is a closed system because thermal energy is not transferred to the environment.
A closed system is an isolated system where there is no transfer of energy with its surroundings. Also the system is not subjected to any external force whose source is external to the system.
the input force is either by hand or electric power. The output force is the the metal at the top of the can being removed and the movement around the can opener
