Answer:
D
Explanation:
In a fixed pulley system, there is load, carried bi the strings and also there is effort which is the number of the turns of strings <em><u>o</u></em><em><u>r</u></em> number of the wheels in the pulley system
Since
There is M.A in the fixed pulley system
But in other objectives, there is load but they lack effort, hence they cannot give mechanical advantage
Let's assume that the pressure given is 771 torr.
Answer:
747.44 torr
Explanation:
The eudiometer tube is a setup that collects gas in a liquid (generally water). After the thermal equilibrium, the gas becomes in equilibrium with the vapor of water above the liquid.
By Dalton's law, the total pressure of a mixture is the sum of the partial pressure of its components. The partial pressure is the pressure that the gas would have at the same conditions if it was alone. So, the pressure of the dry gas is its partial pressure.
The total pressure is the barometric pressure, and the partial pressure of the water vapor at 20°C is 23.56 torr (the value can be found at a thermodynamic table). So, the pressure of the dry gas (P) is:
771 = 23.56 + P
P = 771 - 23.56
P = 747.44 torr
The answer is C. The pressure of a fluid can only depend on density of said fluid!
Current I is the rate at which charge moves through an area A, such as the cross-section of a wire
