In this particular context, 'discrete' means a quantity that's made up of lumps that can't be split up, like a pound of jellybeans, or an ounce of sand. If you cut it down to smaller and smaller samples, you eventually get down to the smallest possible lump ... one jellybean, or one grain of sand ... and there's no smaller amount of it. That also means that a large amount of it can only have certain values ... a number of jellybeans, or a number of grains ... and it can't have values in between.
Electric charge is like that. The smallest possible amount of charge is the amount that one electron carries. No matter how much or how little charge you have in your pocket, it can't be the amount of charge on, say, a million electrons plus half of an electron. It has to be the charge on a whole number of electrons.
Of course, the charge on an electron is so tiny that we never see how charge is actually made up of little lumps that can't be split up. To us, it always looks like you could take as small an amount of charge as you want ... even as little as, say, 0.1 electron's worth, or even less. It looks to us as if charge is . . .
'Continuous' ! That just means it's a quantity that's NOT made of little lumps. You can 'pour' it. You can split it up as fine as you want, and you'll never find any minimum amount. It's smooth like water, not grainy like sand.
Of course we know now that even water has minimum amounts ... molecules ... and if you cut up a molecule of water, then you don't have water any more. And in fact, even pure elements, like hydrogen, are discrete. They're made up of atoms, and if you cut up an atom of hydrogen, then you don't have hydrogen any more ... you have broken pieces of an atom.
But you get the idea. 'Discrete' means made up of small units that can't be subdivided. 'Continuous' means smooth, with no minimum units no matter how close you look at it.
The first thing we should keep in mind is that the watermelon moves with uniform acceleracion equal to gravity (9.81m / s ^ 2)
A body that moves with constant acceleration means that it moves in "a uniformly accelerated motion", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are as follows.
There is no image shown in the question statement. However if we talk about the pyramids as we find them in Egypt, we cannot get a stable inverted pyramid because of the difficulty in terms of balancing it from its centre of mass. In theory one might balance the forces, but in actual, to balance all the load of the structure just on a point is extremely difficult.
However, the term inverted pyramid can be found in ecological system and also used as metaphors in English literature
