Explanation The mole is the SI unit for the amount of substance. It is denoted by mol. According to International Bureau of Weights and Measures, mole is defined as, the amount of substance of a system which contains the same number of constitutive entities (example: atoms, molecules, electron, photon…) as atom in 0 .012 kilograms of carbon-12 isotope. A mole is 6 .022 × 10 23 of anything. 6 .022 × 10 23 Is known as Avogadro number

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…

P-V Diagram

A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and v…

Assuming the normal angle for stairs in a house, 37.0˚ with the horizontal, what is Kevin’s acceleration down the stairs? The sled is always touching at least one stair so you can treat it the same as a ramp. The coefficient of kinetic friction between the sled and the carpeted stairs is 0.708.

A helicopter pulls up and back on the truck with a force of 5.78⋅10^4 N at an angle of 30.0˚ from the horizontal. The truck has a mass of 5.04⋅10^3 kg. The truck’s engine applies a force on the truck that is in the x direction causing the truck to accelerate at 2.09 m/s2 in x. A) What is the force the engine is exerting? B) What is the normal force acting on the truck? Assume no acceleration in y.

Mikasa and her allies, from Attack on Titan, uses omni-directional mobility gear (ODM gear) to move from place to place. The ODM gear launches out wires with grappling hooks they can use to swing through the city. Mikasa, who has a mass of 68.0 kg, holds herself in place not moving with two wires from the ODM gear, as shown below with θ1 = 39.3°. If the tension in the wire labeled T1 is 688 N, what tension, magnitude and direction, is needed in T2?
