Answer: B: It has a negative charge.

Step-by-step explanation:

According to theory espoused by the French physicist, Charles-Augustin de Coulomb, like charges charges will repel each other and unlike charges will attract one another.

This means that objects with negative charges will repel each other. As the first balloon in the question was negatively charged, it would only repel the other balloon if it was negatively charged as well.

Suppose you have the following set of data: 2 mL, 4 mL, 6 mL, 8 mL, 8 mL, 8 mL What is the median of the data set?
artcher [175]

Answer:

7 mL

Step-by-step explanation:

First, arrange the numbers in increasing order from smallest to largest. If there is an odd number of numbers, the median is the middle one. If there is an even number of numbers, the median is the arithmetic mean of the middle two numbers (also called the average; add the two numbers and divide by 2).

2 mL, 4 mL, 6 mL, 8 mL, 8 mL, 8 mL

There are 6 numbers shown in increasing order.

2 mL, 4 mL, 6 mL, 8 mL, 8 mL, 8 mL

Find the arithmetic mean of the middle two numbers, and that is the median.

(6 mL + 8 mL)/2 = 14 mL/2 = 7 mL

Which radical expression represents the difference between the expressions 4 50 + 4 12 − 2 27 and 2 3 ? A) 20 2 B) 20 2 − 2 3 C)
Tcecarenko [31]

Answer:

A 20 sqrt(2)

Step-by-step explanation:

4 sqrt(50) + 4 sqrt(12) - 2 sqrt(27)  minus 2 sqrt(3)

We know that sqrt(a) sqrt(b) = sqrt(ab)

this is the first expression

4 sqrt(25)sqrt(2)  + 4 sqrt(4)sqrt(3) - 2 sqrt(9)sqrt(3)

4*5sqrt(2) + 4*2 sqrt(3) - 2*3 sqrt(3)

20 sqrt(2) +8 sqrt(3)-6sqrt(3)

20 sqrt(2) +2 sqrt(3)

Now we subtract 2 sqrt(3) from the above expression

20 sqrt(2) +2 sqrt(3)  - 2 sqrt(3)

20 sqrt(2)

Find n. 8/12 = n/48. n = ?
Novosadov [1.4K]

Answer:

n = 32

Step-by-step explanation:

<u><em>Given:</em></u>

<u><em></em></u>\frac{8}{12}=\frac{n}{48}

<u><em>Solve:</em></u>

<em />\mathrm{Cross\; Multiply:}

<em />\frac{8}{12}=\frac{n}{48}

\mathrm{48\times8=384}

\mathrm{384\div12=32}

\mathrm{Hence,n=32}
