Answer:
The level of the root beer is dropping at a rate of 0.08603 cm/s.
Explanation:
The volume of the cone is :
Where, V is the volume of the cone
r is the radius of the cone
h is the height of the cone
The ratio of the radius and the height remains constant in overall the cone.
Thus, given that, r = d / 2 = 10 / 2 cm = 5 cm
h = 13 cm
r / h = 5 / 13
r = {5 / 13} h
Also differentiating the expression of volume w.r.t. time as:
Given: = -4 cm³/sec (negative sign to show leaving)
h = 10 cm
So,
<u>The level of the root beer is dropping at a rate of 0.08603 cm/s.</u>
<span>Nitrogen forms : N ≡ N , Oxygen forms: O = O
N: 2s2 2p3 O: 2s2 2p4
Bond order for ¹⁴N - ¹⁶O bond:
= (number of bonding electrons - number of antibonding electrons)/2
= [ (2 from N +4 from O) - 1 from N ] / 2 = 2.5
m1 = 14u m2 = 16u
reduced mass = μ = m1 * m2 / (m1 + m2)
= 112/15 = 7.47 u
μ = 7.47 * 0.001 kg / 6.023 * 10²³ = 1.239 * 10⁻²⁶ kg
k = force constant = 1150 N/m
c = speed of light = 3 * 10¹⁰ cm/s</span>
A compound is a substance that consists of two or more elements, which is chemically combined, meaning that it could only be split by chemical means.
Examples:-
- NaCl is salt, chemically combined of Sodium and Chloride.
- H2O is water, chemically combined of Hydrogen and oxygen.
