Neha and Reha are playing see-saw. Neha is sitting 60 cm away from the fulcrum and Reha is sitting 40 cm away from the fulcrum. Calculate the effort that Reha should apply to lift Neha. The weight of Neha is 360 N.
Answers
Answer:
Reha should apply 540 N to lift Neha.
Explanation:
L = 360 N
LD = 60 m
E =?
ED = 40m
NOW
L * LD = E * ED
360 *60 = E*40
21600/40 = E
540 N = E

h = 3.0 a + 28.2
A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?
Answers
Answer:
h = 34.2 in
Explanation:
h = 3.0a + 28.2
h = height of a girl.
a = age of a girl.
h = 3.0a + 28.2
h = 3.0(2) + 28.2
h = 6 + 28.2
h = 34.2
The estimated height of a 2-year-old girl is 34.2 in.

The formula of calcium chloride is CaCl2, what do those letters and numbers tell you about the compound calcium chloride?
Answers
Answer:
It is a compound made up of one Calclum atom and 2 Chloride atoms.
It comes from a synthesis based reaction:
Ca + Cl = CaCL2
The letters you see are the abbreviations of the elements taken from the periodic table of elements.
Explanation:
The formula of calcium chloride is CaCl2, the letters are the symbolic form of chemical compound and numbers are the total number of moles of the chemical compound.
What is a mole?A mole is the single or the smallest form of any chemical compound or element and it can be in any member but the value of one mole will always be equal to the 2.303 × 10²³ of the carbon atom.
In CaCl2, the Ca is the symbol of calcium and Cl is the symbol of chlorine and the 2 Witten after Cl is the total number of moles attached with it which is making the whole chemical.
Therefore, formula of calcium chloride is CaCl2, the letters are the symbolic form of chemical compound and numbers are the total number of moles of the chemical compound.

determine the empirical formula of the compound formed when 1.2g of magnesium reacts with 3.55g of chlorine.take the molar mass of magnesium and chlorine to be 24g and 35.5g.
Answers
Answer: MgCl2
Explanation:
Convert the masses of Mg and Cl to moles:
Mg: 1.2g/24g/mole = 0.050 moles
Cl: 3.55g/35.5g/mole = 0.100 moles
The ratio of Cl to Mg is 2 to 1: (0.100 moles Cl/0.050 moles Mg), Therefore there must be 2 Cl for every Mg:
MgCl2
This is the empirical formula since all we know is the ratio. If could also be Mg2Cl4, Mg3Cl6, etc, [i.e., (MgCl2)n]

Answers
Answer:
2.5N
Explanation:
since force is inversely proportional to square of the distance apart. that means the ratio of distance apart. so u have 12800×12800÷(6400××6400)=4/1
so the weight will be reduced to 1/4 of 10N
