<u>Answer:</u>
when electric chargers build up on objects is called Static Electricity
<u>Explanation:</u>
When electric charges are built up on objects which can happen due to rubbing or pulling apart of some materials, we get positive charges (+) get collected on surface of one material and negative charges (-) on another. These objects stay charged for some time till they aren't transferred elsewhere through interaction.
This electrically charged surfaces creates a shock type effect when touched. This charging of surfaces of objects due to accumulation of electrons or protons is known as static electricity or static discharge.
Answer: 63 ft^2
Step-by-step explanation:
the formula for the area of a circle is A = π r ^2. the radius (r) is 1/2 of the diameter.
first, we'll plug in the radius of table #1 into the equation (A = π 4 ^2) and get an answer of 50.27 ft^2. then plug in radius of table #2 (A = π 6 ^2) and get 113.1 ft^2. now find the difference of the areas by subtracting (113.1 - 50.27) to get an answer of 62.83 ft^2. which will round up to 63 ft^2.
Let the weight of the full Volume of nails in the box be W.
Let the weight of the box be B.
2/3 W + B = 130 ........i From the first statement.
3/8 W + B = 74 ......ii From the second statement.
Equation (i) Minus (ii)
2/3 W - 3/8 W + B - B = 130 - 74
(16W - 9W) / 24 = 56
7W / 24 = 56.
W = 56 * 24 / 7
W = 192 Pounds.
Substituting V = 64 in equation (i)
2/3 W + B = 130
2/3 * 192 + B = 130
2 * 64 + B = 130
128 + B = 130
B = 130 -128 = 2.
Therefore, weight of box, B = 2 pounds.
