How do internal financing and foreign investment differ?

If $V$ is a vector space over $F$ of dimension $n ,$ prove that $V$ is isomorphic to the vector space of $n$ -tuples over $F$

Standing at the base of one of the cliffs of Mt. Arapiles in Victoria, Australia, a hiker hears a rock break loose from a height of $105.0 \mathrm{~m}$. He can't see the rock right away, but then does, $1.50$ s later. (a) How far above the hiker is the rock when he can hear it? (b) How much time does he have to move before the rock hits his head?

Aluminum is an abundant metallic element in Eartlis crust. It is lightweight, ductile [bendable], corrasion resistant, and a good conductor of electricity. It is used most often in the manufacture of cars, buses, trailers, ships, aircraft, railway and subway cars. Other uses include beverage cans, altominum foil, machinery, and electrical equipment. Aluminum is produced from bauxite (hydrated altminum-oxide) deposits, located mostly in Guinea, Australia, and South America. The United States does not have bauxite deposits it imports it from Brazil, Guinea, and Jamaica. Total world alumintm production is approximately 30 million metric tons per year. U.S. aluminum production is less than U.S aluminum consumption. Leading detminum producers are China and Russia. A major part ( 3 million metric tons per year) of the U.S. aluminum supply comes from recyeling.

Interpret the relationship between aluminum's resistance to corrosion and its use in transportation vehicles.

A space shuttle is in a circular orbit at an altitude of 200 mi. Calculate the absolute value of g at this altitude and determine the corresponding weight of a shuttle passenger who weighs 180 lb when standing on the surface of the earth at a latitude of $45^{\circ}.$ Are the terms "zero-g" and "weightless," which are sometimes used to describe conditions aboard orbiting spacecraft, correct in the absolute sense?

Review. The first stage of a Saturn V space vehicle consumed fuel and oxidizer at the rate of $1.50 \times 104$ kg/s with an exhaust speed of $2.60 \times 103$ m/s. (a) Calculate the thrust produced by this engine. (b) Find the acceleration the vehicle had just as it lifted off the launch pad on the Earth, taking the vehicle’s initial mass as $3.00 \times 106$ kg.

The following table gives the top ten countries in the world whose populations have the highest concentration of type $\mathrm{O}^{+}$blood:

Country	Saudi Arabia	Iceland	Ireland	Taiwan	Australia
Population (%)	$48.0$	$47.6$	$47.0$	$43.9$	$40.0$

Country	Hong Kong	Italy	Netherlands	Canada	South Africa
Population (%)	$40.0$	$39.5$	$39.0$	$39.0$	$38.0$

Find the mean (average), median, and mode of these concentrations of type $\mathrm{O}^{+}$blood in these ten countries.

How many moles of ATP would a yeast cell produce if 6 mol of glucose were oxidized completely in the presence of oxygen? How many moles of ATP would the yeast cell produce from 6 mol of glucose if the cell were deprived of oxygen?

When a cell takes in a food particle by endocytosis, the vesicle that is formed may fuse with a lysosome. How would fusion with a lysosome help the cell digest the food particle?

Perform the below calculation. Express the number and the answer in exponential form and with the appropriate number of significant figures.

$$\text{$\dfrac{\text{320 $\times$ 24.9}}{\text{0.080}}$} =$$

A 0.10-kg apple falls on Earth, whose mass is about $6 \times 10^{24} \mathrm{kg}$.Which is true of the gravitational force that Earth exerts on the apple? (a) It is bigger than the force that the apple exerts on Earth by almost 25 orders of magnitude. (b) It is the same magnitude. (c) We do not know the magnitude of the force the apple exerts on Earth.

Complete the following sentences: Electrons in the external circuit flow from the $_____$ electrode to the $_____$ electrode. Negative ions move in the salt bridge from the $_____$ half-cell to the $_____$ half-cell .

Many people mistakenly believe that the astronauts that orbit Earth are “above gravity.” Calculate g for space shuttle territory, 200 km above Earth’s surface. Assume Earth’s mass is

$$6.0 \times 10^{24}kg,$$

and its radius is

$$6.38 \times 10^6 m (6380 km).$$

Your answer is what percentage of

$$9.8 m/s^2?$$
