My question may be for a specialised mechanical engineer in rotary equipments who can answer to it exactly. I wished to know the relation between the bearing number and the dimensions of anti friction bearings like ball bearing and roller bearing. Thank you.

Hello, I am having a lot of trouble with patterns, can you help me please? This is for school and it's due soon I just can't figure it out. If you can, please post them and I will have so much less stress on my mind... thankyou!


Find the next two numbers in each pattern.
A) 4, 8, 12, 16, ______, _______
B) 3, 9, 27, 81, ______, _______
C) 144, 121, 100, 81, ______, _______
D) 3, -12, 48, -192, ______, _______
E) 7, 10, 14, 19, ______, _______
F) 2, 3, 7, 16, ______, _______

And then create an expression for the general term of each pattern.
(e.x. term n = (n) x (4) it's a sequence of numbers and it goes in order, term 1, term 2, term 3.... )

didn't astronomers or scientists found anything travels faster than light?What is it? and how much faster? does that destroy relativity?

A rocket ship in uniform flight has mass, velocity, momentum, and kinetic energy. It has the alien technology to be able to decrease its mass while maintaining its momentum. Does it take work to lose its mass, and, if so, how much work does it take to lose all of it and how fast it will then be going? Use relativistic momentum and energy, not Newtonian.

People talk about stuff like a villion and one or 2 villion but apparently when scientists try to write to deal with bigger numbers than a villion it makes their brains swell and they get violent nosebleeds because it's not humanly possible.

Apparently there is no bigger number, once you hit a villion you've maxed out the whole number scene and you enter a weird limbo where the laws of numeracy breakdown.

Is this true or just simply damn true?
