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

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?
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
