Answer : The mass of a sample of water is, 888.89 grams
Explanation :
Latent heat of vaporization : It is defined as the amount of heat energy released or absorbed when the liquid converted to vapor at atmospheric pressure at its boiling point.
Formula used :
where,
q = heat = 2000 kJ = 
(1 kJ = 1000 J)
L = latent heat of vaporization of water = 
m = mass of sample of water = ?
Now put all the given values in the above formula, we get:
(1 kg = 1000 g)
Therefore, the mass of a sample of water is, 888.89 grams
Who pays the income tax, the payroll tax, the estate and gift taxes? Who
bears the burden of the gasoline and tobacco taxes? If Congress were to
raise this tax rate, or lower that tax deduction, who would gain and
who would lose? The outcomes of the political battles over changes in
the tax system often hinge on the answers to such questions. This paper
will discuss the economic consequences of taxation and the factors that
influence where the burden of various taxes really falls. It will review
some of the discussions in the economic literature. Finally, it will
suggest that a shift to a markedly different type of tax system would
benefit all players in the economy.
Answer:
Given, length of wire, l = 2m
cross sectional area , A = 10^-4 m²
Load , F = 102kgwt = 102 × 9.8 N
extension of wire, ∆l = 0.1cm = 0.001m
Longitudinal stress = F/A
= 102 × 9.8/(10^-4)
= 999.6 × 10^4 ≈ 1 × 10^7 N/m²
Longitudinal strain. = extension of wire/original length of wire = ∆l/l
= 10^-3/2 = 5 × 10^-4
we know, Young's modulus = longitudinal stress/longitudinal strain
= 1 × 10^7/5 × 10^-4
= 20 × 10^9 N/m²
