Is a chromosome, two chromatids bonded together by a centromere? then, what is a chromatid? Also what is meant when they say that there are two sets of chromosomes? do they mean that there are 2 chromosomes together with four chromatids? what also is the difference between homologous...

Is amplitude always perpendicular to the rest axis? in a wavelength amplitude it the distance between either the crest or through from the equbilium line. then in the case of transverse vibration, what is its amplitude? thanks

Hello, i am so confused Newton's universal gravitation states FG= Gm1m2/r squared and in this case FG stands for the force of gravitational attraction between any 2 objects, but why is Fg (gravitational field strength) equaled to fg=Gm/r squared? why are FG and Fg used interchangeably? i do not...

Newton Is gravitational field strength same as Newton's universal constant? If not how exactly are they different? please explain simply thanks <Moderator's Note: Multiple Threads Merged>

Hello, I just read a book reagarding Newton and his laws and had few questions about it. What is Gravitational field strength exactly and what is Newton's universal gravitational constant? Aren't they the same thing? please explain these two concepts simple enough for me to understand and to...

because according to the law of conservation of energy, the gravitational potential energy and the kinetic energy would just stay the same the whole time but it is only slightly dissipated by heat, where else does it all go?

explain in details please

When a pendulum is let go from an elevated area, it will eventually stop swinging. But if this occurs then where had the mechanical energy gone to?

please answer simple and descriptively

how could the process of the kidney's process of reabsorpting the water be simulated through a man made experiment?

As the balloon rises, the force of gravity pulls on the balloon, but which force is strong enough to pull the balloon up so that it floats in the air? thanks

How does potassium affect the blood pressure? how does it lower the blood pressure with the help of the kidney(collecting duct)? thanks

Acceleration as in the gravity 9.8m/s/s thanks for the reply

When an object free falls, its accerleration is constant, but does its speed change? If so is it practicing uniform or non uniform motion?
