Profit = 1350-1184=166 AED
Loss= 1350-166 =1184
Answer:
The magnitude of the torque due to gravity if it is supported at the 28-cm mark is 0.5 N-m.
Explanation:
Given that,
Mass of the meter stick, m = 0.3 kg
Center of mass is located at its 45 cm mark.
We need to find the magnitude of the torque due to gravity if it is supported at the 28-cm mark. Torque acting on the object is given by :
or
So, the magnitude of the torque due to gravity if it is supported at the 28-cm mark is 0.5 N-m.
Answer : The correct statement is (C).
Explanation :
Statement A : This statement is incorrect because the temperature of the gas sample is directly related to the average kinetic energy of the gas particles.
Statement B : This statement is incorrect because at STP, equal volume of all gases have the same number of molecules.
Statement D : This statement is incorrect because the ideal gas works well when the inter-molecular force of attraction between the gas molecules are negligible.
Statement C : This statement is correct because when molecules collides with the wall of container, they exert small force on the wall of the container. The pressure exerted by the gas is due to the sum of all the collision forces. That means more the particles hit the walls of container, the higher the pressure.
Answer:
Faraday's law states that electromotive force induced is proportional to the rate of change in magnetic flux
