What does the angular momentum quantum number determine?

1 answer:

5 0

The angular momentum quantum number, or spin quantum number, tells us the spin on an electron. It has a value of either +1/2 or -1/2, depending on spin direction.
The magnetic quantum number tells us the number of orbitals available within a subshell. Its value is 0, 1, 2, 3
The principal quantum number tells us the shell number and has integer values starting from 1.

In abiding by the code of ethics, forensic scientists must possess what characteristics or ethics?

bixtya [17]

Scientists must have an unbiased type of investigation. These type of science requires three major characteristics for it to be functional and sticked to the truth: they must be impartial, accuarate and truthful. Without these characteristics there is no way forensic science must be treated as science.

Q4. Consider the skier on a slope shown in the figure below. Her mass including equipment is 55.0 kg.

Shkiper50 [21]

Answer:

Part a)

When there is no friction then acceleration is

$a = 4.14 m/s^2$

Part b)

if there is friction force along the inclined then acceleration is

$a = 3.33 m/s^2$

Explanation:

Part a)

As we know that the skier is on inclined plane

So here if there is no friction then net force along the inclined plane is given as

$F = mg sin\theta$

now acceleration of the skier is given as

$a = \frac{F}{m}$

$a = g sin\theta$

$a = 9.81(sin25)$

$a = 4.14 m/s^2$

Part b)

if there is friction force along the inclined then net force along the inclined plane is given as

$F = mg sin\theta - F_f$

now acceleration of the skier is given as

$a = \frac{F}{m}$

$a = g sin\theta - \frac{F_f}{m}$

$a = 9.81(sin25) - \frac{45}{55}$

$a = 3.33 m/s^2$

Explanation:

The skeletal system helps maintain mineral homeostasis by regulating the level of calcium and other minerals in the blood by storing or releasing them from bones as needed. Bones also regulate blood glucose and fat deposition through the secretion of the endocrine hormone osteocalcin.
