Can someone please explain the quantum theory in simple terms

1 answer:

6 0

Quantum theory is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the atomic and subatomic level. The nature and behavior of matter and energy at that level is sometimes referred to as quantum physics and quantum mechanics.

The polar coordinates of the collar A are given as functions of time in seconds by r = 2+ 0.7 t2 ft and ????= 3.5t rad. What are

r-ruslan [8.4K]

Answer with explanation:

Part a)

$v_{radial}=\frac{dr}{dt}=\frac{d(2+0.7t^{2})}{dt}\\\\v_{radial}=1.4t\\\\\therefore v_{radial}|_{t=4}=1.4\times 4=5.6ft/s\\\\v_{angular}=r|_{t=4}\times \frac{d\theta }{dt}=13.2\frac{3.5t}{dt}=46.2fts^{-1}\\\\\therefore v=\sqrt{v_{radial}^{2}+v_{angular}^{2}}\\\\v=46.53ft/s$

Part b)

$a_{radial}=\frac{d^{2}r}{dt^{2}}=\frac{d^{2}(2+0.7t^{2})}{dt^{2}}\\\\a_{radial}=1.4ft/s^{2}\\\\a_{angular}=r\times \frac{d^{2}\theta }{dt^{2}}\\\\a_{angular}=r\times \frac{d^{2}(3.5t) }{dt^{2}}\\\\\therefore a_{angular}=0\\\\\therefore Accleration=1.4ft/s^{2}$

tia_tia [17]

True

Explanation:

It is correct to say that the salinity of the oceans has been relatively constant throughout geologic time because salt is removed at the same rate it has been added.

Salinity is the amount of dissolved salt found in the ocean. It is the degree of saltiness of the ocean.

The rate at which salt has been added into the ocean over the years through geologic time has been very constant.
Most salts in the ocean comes from land.
Also the rate it has been removed is fairly constant.
The salinity of ocean has once been used to date the age of the earth.

A bus traveling at 25.2mi/h speeds up at a constant rate of 9.2x10^-3 m/s^2. What velocity does it reach 25min later?

Softa [21]

Answer: actually to solve this u must know what 3.2m/s2 is..do u know it ??...wel let me tell...3.2m/s2 means that in every second the speed of the body increases by 3.2m/s..so if it acts for 6.8 seconds..increase in speed will be 3.2*6.8 however note that this is the increase in speed.. have to change this in km/hr & add this to the initial speed(27km/hr) to get the answer....hope this has cleared ur doubts....

A lightweight object and a very heavy object are sliding with equal speeds along a level frictionless surface. They both slide u

boyakko [2]

Answer:

No object rises a greater height. They both rise the same height.

Explanation:

Since the kinetic energy = work done by gravity

1/2mv² = mgh

h = v²/2g where h is the height and v the speed.

Since the speed is the same for both objects, the height moved is the same since the expression for the height moved is independent of their masses but dependent on their speeds.

So, no object rises a greater height. They both rise the same height.

The drawings show two examples in which a ray of light is refracted at the interface between two liquids. In each example the in

Nataly [62]

Answer:

Possible options:

A. nA, nC, nB

B. nA, nB, nC

C. nC, nB, nA

D. nC, nA, nB

E. nB, nA, nC

Answer is D

Explanation:

When the light is refracted into liquid B it is bent away from the normal, so that nA > nB. When the light is refracted into liquid C it is bent toward the normal, so that nC > nA. Therefore, we conclude that nC > nA > nB
