B) Si [No]
C)F [No]
D) O6 [No, multiple atoms, but same element]
124) The formula for water is H2O meaning there are 2 Hydrogen atoms and 1
Oxygen. What is the atomic mass of one molecule to the nearest hundredth?
A) 15.99
B) 16.99
C) 17.99 [Yes, 16 + 2*1 = 18]

Boils
Celsius is based on the freezing and boiling points of water.
Water freezes below 0 degrees Celsius (32 degrees Fahrenheit), and it boils above 100 degrees Celsius (212 degrees Fahrenheit).
The force exerted on the Kite is 49.6 N.
<u>Explanation:</u>
Force is nothing but the product of pressure exerted by the wind on the kite and the area of the kite.
F = P × A
Where,
F is the Force in Newton = ?
P is the Pressure = 113 Pa = 113 N/m²
A is the Area of the Kite
A = 0.836 m × 0.525 m = 0.4389 m²
Now, we can find the force as,
F = 113 N/m² × 0.4389 m²
= 49.6 N [ ∵ In the units, m² gets cancelled]
So the force exerted on the Kite is 49.6 N.
Volume equals area to the third power
