Quantum mechanics means dealing with physics at a very small level. Or u can say microscopic level. Studying physics at sub atomic level

Study regarding protons, electrons and quarks include in this study.

Also the laws of physics at normal level fail in quantum mechanics.

Laws like uncertainty principal of Heisenberg, wave nature, are there

(So if u want to write an essay, first u can tell about) the difference between normal sized objects and the subatomic ones. And how physics act upon them

Then u can write about how laws fail for microscopic things so we need to study quantum mechanics.

And elaborate every paragraph like i ve written in points.

hope that will make ur essay complete ♥

3 small identical balls have charges -3×10^-12 ,8×10^-12 and 4×10^-12 find the charge​
Norma-Jean [14]

Answer:

  3×10^-12 C  

Explanation:

The total of the three charges is ...

   (-3 +8 +4)×10^-12 C = 9×10^-12 C

Assuming the charge is equally distributed between the balls when they are brought in contact, the charge on each ball will be ...

  (9/3)×10^-12 C = 3×10^-12 C

Suppose a ball is dropped from shoulder height, falls, makes a perfectly elastic collision with the floor, and rebounds to shoul
Bezzdna [24]

Answer:Same magnitude

Explanation:

When ball is dropped from shoulder height h then velocity at the bottom is given by

v_1=\sqrt{2gh}

if it makes elastic collision then it will acquire the same velocity and riser up to the same height

If m is the mass of ball then impulse imparted is given by

J=m(v_2-v_1)

J=2m\sqrt{2gh}

Thus impulse imparted by gravity and Floor will have same magnitude of impulse but direction will be opposite to each other.

A mason is shot with a constant speed of 7.5 x 10²m/sinto a region, when an electric field produces acceleration on the mason of
nadya68 [22]

Answer:

Distance, d = 0.1 m

It is given that,

Initial velocity of meson,

Finally, the meson is coming to rest v = 0

Acceleration of the meson,  (opposite to initial velocity)

Using third equation of motion as :

s is the distance the meson travelled before coming to rest.

So,

 

s = 0.1 m

The meson will cover the distance of 0.1 m before coming to rest. Hence, this is the required solution.
