Choosing 3 toppings for your sundae out of a list of 15. Permutation or not?.
Since the order is not important, the combination formula is used.
When to use the combination and the permutation formula?If the order in which the options are taken is important, permutation is used.Otherwise, if the order in which the options are taken is not important, combination is used.In this problem, the order in which the toppings are chosen is not important, for example, chocolate and strawberry is the same topping as strawberry and chocolate(if we considered 2 toppings), hence it is a combination.

What is true when the units in ending inventory increase during the year.
The true option is : Net income is higher for absorption costing than for variable costing.
What is Net income?Net income is the actual amount left to an individual or a company, after taken out all other expenses.
Here, absorption cost are those cost that includes the costs like variable costs as well as the overhead costs which are fixed in nature.
This means that an increase in the closing stock balance, the net income for the absorption costing shows more than that of the variable costing.
Hence, the net income for absorption costing is higher than variable costs when the closing inventories increases throughout the year.

Two point charges are 4 cm apart. They are moved to a new separation of 8 cm. By what factor does the resulting mutual force between them change?.
The resulting mutual force between the charges will change by a factor of 1/4.
States that the force between two charges in an electric field is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.
From the law above.
F α 1/r²........................ Equation 1If the distance between the charges is changed from 4 cm to 8 cm, the factor at which the force will change is
Factor = (1/8²)/(1/4²)Factor = (1/64)(16)Factor = 1/4.Hence, The resulting mutual force between the charges will change by a factor of 1/4.

Find the momentum of a 22. 5 g bullet fired at 532 m/s.
Answer: 11.97 kg m/s
Explanation: The formula for momentum is P = mv and since we are given the mass and the velocity of the bullet, w are basically all set.
Since kilograms is the standard unit for mass, we can
convert 22.5 g to kilograms to get 0.0225 kg by dividing by 1,000.
So we have P = (0.0225 kg)(532 m/s) and this gives us 11.97 kg m/s.

I have an unknown volume of gas at a pressure of 0. 50 atm and a temperature of 325 k. If i raise the pressure to 1. 2 atm, decrease the temperature to 320 k, and measure the final volume to be 48 liters, what was the initial volume of the gas?.
Answer:
117 liters
Explanation:
P1 = 0.50 atm, T1 = 325 K, V1 = ?
P2 = 1.2 atm, T2 = 320 K, V2 = 48 liters
Use P1*V1/T1 = P2*V2/T2
so V1 = V2 * (P2/P1) * (T1/T2) = 48 *(1.2/0.50) *(325/320) = 117 liters

Arrange the given compounds based on their relative brønsted acidities.
Arranging the given compounds based on their relative bronsted acidities :
I.e. Strongest to weakest
H-Br ---> H-F --- > H-SH -----> H-NH₂ ----> H-CH₃Factors affecting relative bronsted aciditiesThe arrangement of the compound based on their relative bronsted acidities is dependent on certain factors which are :
Stability of the conjugate base increment Increase in electronegativity ( this leads to increase in holding a negative charge ).Increase in size ( leads to increase in holding negative charge due to large electron cloud ).From the list of compounds given F⁻ is less stable than Br⁻ and this makes H-Br more stronger than H-f

The diameter of a semicircular pond is 7 m. Find its perimeter.
Answer:
Approximately 18 m
Explanation:
Hi there!
What we need to do to solve this question is the following:
1. Find the circumference of the circle, as if the pond is CIRCULAR and NOT SEMICIRCULAR
2. Divide the circumference in half to find the length of the round part of the semicircle
3. Add 7 m to that value to get the straight side of the semicircle
1. Find the circumference of the circle (C)
[tex]C=\pi d[/tex] where d is the diameter
Plug in the diameter 7 m
[tex]C=\pi (7)\\\\C=7\pi[/tex]
We're not going to solve this just yet, but we will in the end. This is so that we can get a more precise answer.
2. Halve the circumference
[tex]\displaystyle\frac{7\pi}{2}[/tex]
3. Add 7 m
[tex]\displaystyle\frac{7\pi}{2} + 7\\\\= 17.99557\\\\\approx 18[/tex]
Therefore, the perimeter of the pond is approximately 18 m.

A first order reaction initially contains 1. 00 × 10²⁰ molecules. If the reaction has a half-life of 20. 0 minutes, how many molecules remain unreacted after 80. 0 minutes?.
Using proportions, it is found that [tex]1.25 \times 10^{19}[/tex] molecules remain unreacted after 80. 0 minutes.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the half-life of the reaction is of 20 minutes, hence:
After 20 minutes, 50% of the molecules are unreacted.After 40 minutes, 25% of the molecules are unreacted.After 80 minutes, 12.5% of the molecules are unreacted.Then:
[tex]0.125 \times 10^{20} = 1.25 \times 10^{19}[/tex]
