Charge on atom is due to electron
Electron have negative charge while proton have positive charge and neutron have no charge. If there are 10 proton (10 positive charge)
Answer:
The area covered by the planters is 113.6 square inches.
Step-by-step explanation:
Assuming that the dimmensions of the greenhouse are 4 1/4 by 1 2/3 inches. We first need to convert them from mixed fractions to normal fractions, we do that by summing the integer part to the fraction one. We have:
length = 4 + 1/4 = 16/4 + 1/4 = 17/4 inches
width = 1 + 2/3 = 3/3 + 2/3 = 5/3 inches
The area of the greenhouse is given by:
area = length*width
area = (17/4)*(5/3) = 85/12 = 7.1 square inches
Since there is an array of 4x4 there is a total of 16 greenhouses and it's total area is 16*7.1 = 113.6 square inches
Answer:
14.6°C
Step-by-step explanation:
Method 1
Higher value - lower value
12.2°C - (-2.4°C) *two negatives make a positive
12.2 + 2.4
14.6°C
Method 2
-2.4°C to 0°C = 2.4 increase (+2.4°C)
0°C to 12.2°C = 12.2 increase (+12.2°C)
Total change = 12.2 + 2.4= 14.6°C
