law of increasing opportunity cost

The cost of a coat was $50. Its price was increased by 15%. Estimate the increased cost of the coat. => $59.50 or $61.50 or $55.50 or $57.50..

When small spherical bodies move through a viscous medium, the bodies drag the layers of the medium that are in contact with them. This dragging results in relative motion between different layers, which are away from the body. Therefore, a viscous drag comes into play, opposing the motion of..

. Thus, the gas gains energy as heat gets supplied to it and it loses energy as work is done by it. Suppose, in a process, an amount D Q of heat is given to the gas and an amount D W of work is done by it, the total energy of the gas must increase by ( D Q - D W). As a result, the entire ..

Stokes' Law - When small spherical bodies move through a viscous medium, the bodies drag the layers of the medium that are in contact with them. This dragging results in relative motion between different layers, which are away from the body. Therefore, a viscous drag comes into play, oppo..

When a gas is heated the molecules move faster increasing the pressure. But to maintain the pressure constant, the force of collision is compensated with an increase in volume. So, at constant pressure the volume of the gas increases with temperature. By kinetic gas e..

. Fig: 2.3 - Plot of P versus 1/V The P-V curve for a given gas is different at different temperatures. The plot of 'PV' against 'P' at different temperature is known as Isotherms. The higher curve corresponds to higher temperature. Boyle's law expresses the compressible nature of gas, wh..

Moseley's Law - Moseley had done experiments on the characteristic X-rays and this led to the development of the concept of atomic number. The periodic table was made according to the atomic weight in earlier days. But some anomalies were found in such an arrangement. Moseley measured the..

Charles' Law - Charles formulated this law in 1787 giving the relationship between volume and temperature of a gas. This law stated that at constant pressure, the volume of a given mass of gas increases or decreases by 1/273 of its volume at 0 o C for every o..

The cost of an article during six years is shown in the line graph. By what amount did the cost of the article increase from 1997 to 1999? => $15 or $5 or $10 or $3..

The cost of a movie ticket is $6, which increases by 4% each year. Find the cost of the ticket after 6 years. => $36 or $13.00 or $8.00 or $16.00..
