What is the functional group in amines?


What are the functional groups in amino acids?


How does an R group determine if an amino acid is acidic, basic, or nonpolar?

This is like my third question, but if energy transforms into mass when you accelerate, can mass also be transformed into energy? In one of the answers someone told me the amount of mass was multiplied by the speed of light squared to get how much energy would come out if it. If it is possible, can you imagine what a massive amount of energy we could get of something the size of a car?!

I have noticed when I fall asleep, that when I wake up I am so hot! My kids do that too, as soon as they fall asleep they start to sweat. Does your body temperature rise when you are in sleep mode?

For highly sensitive electronic designs, u will notice that a push on the push button does not just bridge or unbridge the circuit.There is always very tiny smaller deminishing bounces that follows.
As an electronic engineer or aspiring engineer what type of push ciruit or deboucing switch can be better use.

I have heard that a normal magnets pole is decided by looking it turn on to the pole. but how do we decide the earths north pole is at there itself, why cant it be the south pole.

A box of textbooks of mass 24.4 kg rests on a loading ramp that makes an angle \alpha with the horizontal. The coefficient of kinetic friction is 0.270 and the coefficient of static friction is 0.330 .

As the angle \alpha is increased, find the minimum angle at which the box starts to slip.

At this angle, find the acceleration once the box has begun to move.
Take the free fall acceleration to be g = 9.80 m/s^2.

At this angle, how fast will the box be moving after it has slid a distance 5.50 m along the loading ramp?
Take the free fall acceleration to be g = 9.80 m/s^2.

I've been set a maths problem, but I think that there might have been a mistake in it. It says, "Let G be a finite abelian group and let n:-|G|. Show that for some prime number q there is an element g of order q in G (Hint: Take any non-identity element h in g and show that some power of h has prime order).

My question is, how do you know that there is a non-identity element in the group? A set comprised of just the identity element along with some binary relation * will satisfy the group axioms, and the only element in this group has order 1. But then, as I have been taught that 1 is not prime, it appears that there is no element in this group that has prime order. (I can prove what is required assuming that there is some non-identity element in the group, as the question suggested, but surely it doesn't seem right to just make this assumption?)

This disscussion could belong in more than one topic from Math, Space, Biology, Psychology and beyond.

You could have a dream that seems to take for ever but once waking up that dream was only minutes long. Is time dilation taking place? In the dream everything was moving in a normal manner and not in fast forward or slow motion.

Was 1 second in the dream a hundredth of a second in the real world?

A stockroom worker pushes a box with mass 11.4 kg on a horizontal surface with a constant speed of 3.90 m/s. The coefIficient of kinetic friction between the box and the surface is 0.200 .

What horizontal force must be applied by the worker to maintain the motion?
Take the free fall acceleration to be g = 9.80 m/s^2.

If the force calculated in part (A) is removed, how far does the box slide before coming to rest?
Take the free fall acceleration to be g = 9.80 m/s^2.
