A rank-m tensor is a mathematical object that represents N^m real numbers, where N is the dimension of space. rank-0 Tensor: represents a single real number and is usually called a scalar. Examples of …

The Casimir effect is a small attractive force that acts between two close parallel uncharged conducting plates. It is due to quantum vacuum fluctuations of the electromagnetic field. According to the …

Dec 27, 2015 · Electrostatic is not a force. Electrostatic refers to highly ionized regions. For example, when you see lightning it is the release of an electrostatic charge that had been accumulating in the …

Assign a positive or negative sign to the force depending on its direction, then add the two forces to get the net force. Acceleration is a vector quantity, meaning that it also has direction in it. You can …

An object with a mass of #7 kg# is on a surface with a kinetic friction coefficient of # 8 #. How much force is necessary to accelerate the object horizontally at # 4 m/s^2#? How do you evaluate #e^ ( ( …

The force exerted by the wedge is equal to -"1000 N". You're actually dealing with an equilibrium problem. However, the trick here is to distinguish between translational equilibrium and rotational …

How can friction cause motion? How is the force of friction related to the normal force? If two people pull on either side of a rope with a force of 250 N why do we say that the force of tension in the rope 250 …

When a moving object collides with a stationary object of identical mass, the stationary object encounters the greater collision force. Is that true or false? Why? Why is law of conservation of …

The “reaction” force is a gravitational force acting vertically upwards on the Earth. The “reaction” must be: ① A force of the same type, i.e. a gravitational force since the action is a gravitational force. ② …

The given situation"*" is depicted in the figure below Let a be side of the square. As shown in the figure charge Q placed in one corner experiences three forces. Force vecF_3 due to charge Q placed at …
