We know or talk about 2D, 3D, 4D. But we can extend it to ND also, but that would be hypothetical, i.e, we can imagine for nD also.

Physics major at IIT-J researching in theoretical particle physics.

We have 3 "physical" dimensions. The 4th dimension we consider in relativity is time, which constitutes the understanding of the spacetime continuum. There is also a branch of cosmology that believe gravity to be the 5th dimension.

This is still controversial but a curious one must know there is a belief that there exist approximately 11 physical dimensions. Reply back if you are really interested in the names of those dimensions.

An elevator weighs 3000kg. What is its acceleration when the in the tension supporting cable is 33000N. Given that g = 9.8m/s2.
M = 3000 kg g = 9.8 m/s² T = 33000 a = ? Ma = Mg - T 3000 * a = 3000 * 9.8 - 33000 3000a = 29400 - 33000 3000a = - 3600 a = - 1.2 m/s².

Why is only the speed of light constant in all frames of reference?
The only thing that affects the speed of light is the refractive index of the medium through which it moves, and for space, this number is 1.000000 and gives you the maximum possible speed of light.

A railway carriage of mass 9000 kg moving with a speed of 36 kmph collides with stationary carriage of the same mass. After the collision, the carriages get coupled and moved together. What is their common speed after collision? What type of collision is this?
The objects move together after the collision and have a common velocity. So it's a perfectly inelastic collision. To find the velocity we use Law of conservation of linear momentum. Given velocity v1=...
