Use the saving-investment diagram to analyze the effects of the following on national saving, investment, and the real interest rate. Explain your reasoning.
a. Consumers become more future-oriented and thus decide to save more The government introduces an investment tax credit (offset by other types of taxes, so total tax collections remain unchanged).
b. A large number of accessible oil deposits are discovered, which increases the expected future marginal product of oil rigs and pipelines. It also causes an increase in expected future income.
Find the value of m for which the system of equations
x - 2y + z = 0,
-2x - y + 3z = 0
y + z = m
has only trivial solution.
Find the class boundaries, midpoints, and size for each class.
(a) 32 – 38
(b) 86 – 104
(c) 895 – 905
(d) 12.3 – 13.5
(e) 3.18 – 4.96
The temperature of an ideal gas remains constant while the absolute pressure changes from 100 kpa to 800 kpa. If initial volume is 100 liters, what is the final volume in liters?
given the demand function p=1000-Q express TR as a function of Q and hence sketch a graph of TR against Q. What values of Q maximizes total revenue, and what is the corresponding price?
Neurons send ____ in response to stimuli.
the recognition that business activities have an impact on society and the environment and that the consideration must be made of the impact in the decision making
3. An electric generator consists of 100 turns of wire formed into a rectangular loop 50.0 cm by 30.0 cm, placed entirely in a uniform magnetic field with magnitude B = 3.50 T. What is the maximum value of the emf produced when the loop is spun at 1000 rev/min about an axis perpendicular to B ?
1. A UHF television loop antenna has a diameter of 11 cm. The magnetic field of a TV signal is normal to the plane of the loop and, at one instant of time, its magnitude is changing at the rate 0.16 T/s. The magnetic field is uniform. What emf is induced in the antenna?
Consider the configuration shown below, with a negative charge Q0 at position x0=0 and another positive charge Q1 at position 1 along the x-axis. Determine the position At which position x2 could another positive charge charge Q2 be added, such that the total force on Q0 is 0? Give two examples of x2 and corresponding Q2, in terms of x0, x1, Q0 and Q1 (or a subset of these variables).
