E p = m · g · h
E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J
E p ( picture frame ) = 6.86 J
( same gravitational potential energy as the book )
6.86 = 0.5 · 9.8 · h
6.86 = 4.9 h
h = 6.86 : 4.9
h = 1.4 m
Answer: ... to a height of 1.4 m.
Uhh like any other job it varies but uhh on average I’d say about $50,000 a year. But it ranges from 15,000 to 120,000. And the average hourly pay is like $16-$25 and hour.
Hope this helps!
Answer: Option (A) is correct.
Explanation:
In a competitive market, when the demand curve i.e. the marginal benefit curve is exactly equal to the supply curve i.e. marginal cost curve and at this point the sum of consumer and producer surplus is maximized then an equilibrium is set in an economy and economic efficiency is obtained.
Inefficiency occurs at a point where there is a disequilibrium in an economy which means that competitive equilibrium is not achieved by the economy.
Answer:
A)not negate the logical basis for trade in the Ricardian model.
Explanation:
Trade can be regarded as basic economic concept which involves the buying as well as selling of goods and services, having a compensation that is been paid by a buyer to a seller.
The Ricardian model can be regarded as model that incorporates the standard assumptions of a perfect competition. This model in it's simplest form give assumption of two countries that are producing two goods, but uses one factor of production, the goods here are usually assumed to be identical, or to be homogeneous, within as well as across countries. It should be noted that when there is higher wage, there will be greater number of workers that are willing to work and vice versa, which defined the relationship between wages and productivity. productivity gives the
measurement of how efficiently labor
is been utilized when producing goods and services.
It should be noted that If labor productivities were exactly proportional to wage levels internationally, this would not negate the logical basis for trade in the Ricardian model.
Answer:
Present value (PV) = $1,000
Interest rate (r) =8% = 0.08
Number of years (n) = 18 months = 1.5 years
No of compounding periods in a year = 4
Future value (FV) = ?
FV = PV(1 + r/m)nm
FV = $1,000(1 + 0.08/4)1.5x4
FV = $1,000(1 + 0.02)6
FV = $1,000 x 1.1262
FV = $1,126
Explanation:
The amount to be received in 18 months is $1,126. This is obtained by compounding the present value at 8% compounded quarterly for 18 months. The formula to be applied is the formula for future value of a lump sum(single investment).
