Maggie is trying to find out if the amount of sugar in a liquid affects the amount of time it takes to freeze
A good hypothesis is: The more sugar in the drink the longer it takes to freeze
Conclusion= she concludes that her hypothesis is correct as the unsweetened tea froze the fastest while the root beer took the longest time as it contained the most sugar

If X be a vector 3 X represents  3 added to X  3 times of X  the ratio of X and 3  None

jolli1 [7]

Answer:

The correct option is;

3 times of X

Explanation:

The algebraic properties of a vector are;

Multiplicative identity for real numbers 1

1P = P for each P

Scalar associative property = r(sP) = (rs)P

Scalar distributive property (r + s)P = rP + sP

Vector distributive property r(P + Q) = rP + rQ

Additive inverse of a vector such that a vector P has an inverse -P such that we have;

P + (-P) = 0

Vector associative property (P + Q) + R = P + (Q + R)

Vector commutative property P + Q = Q + P.

If light is used to promote the electron, what are the selection rules for the initial and final spin and orbital angular moment

loris [4]

Answer:

(1) $\Delta S=0$

(2) $\Delta L=0, +1,-1$ but $J=0 to J=0$ transition not allowed.

Explanation:

Atoms can be described by the quantum number n, spin quantum number S, angular momentum quantum number L, and total angular momentum quantum number J. Based on approximation Russel- Saunders electron coupling, the atomic term symbol can be written as $L_{J} ^{2S+1}$ .
