1.) A jogger runs directly east for 4 km, then turns and goes northwest for 9 km. He then travels directly south for 3 km. How far is he from the starting point? (km)

2.) In what direction is he from the starting point(measured as an angle counterwise from the east axis, units are deg)? (Northwest is the direction lying exactly half way between north and west.)

1. Briefly explain the difference between the United Nations 8 Millennium Development Goals (MDGs) and the 17 Sustainable Development Goals (SDGs)

2. Briefly explain why China is still categorized as a “Global South” country today despite its economic and military strength.

3. What are the three countries that eventually became part of the Global North group in the late 1990's - mid 2000's.

Abbie exchanged the following business assets. Which situation exemplifies a fully nontaxable exchange for Abbie?

An improved lot traded to Iva for a rental house. Abbie paid the $2,000 selling expense.

An unimproved lot in South Carolina traded for Terrell's unimproved lot in Canada.

A delivery van traded with Nina for a refrigerator unit.

A commercial sewing machine and $5,000 traded with Rosie for another commercial sewing machine.

A plane leaves the airport in Galisteo and flies 170km at 68.0 degrees east of north and then changes direction to fly 230 km at 48.0 degrees south of east, and then changes direction to fly 120 mi west, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, in which direction and how far should this crew fly to go directly to the plane?

Describe how Amp`ere’s force law and Amp`ere’s law for magnetization fields can be used to explain the forces between permanent magnets. From this perspective, how does the arrangement and orientation of the magnets lead to either an attractive force or a repulse force? How does the convention of North and South polarity relate to the magnetization field of the magnet? I do not need a mathmatical explanation but a physical explanation.

True or Falsea: If False, why?

1. The C. A. P. L. formula allowed the South to control its own credit by issuing investment bonds based on slave-based mortgages backed by guarantees from state legislatures.

2. The economic boom of the 1830s was made possible by strict state regulation of bank credit, securitization of slave-based mortgages, and high-risk speculation on future cotton revenues.

Which of the following statements is true?

Select the correct answer

a.NONE OF THE STATEMENTS ARE TRUE

b.Electric forces depend on velocity of a charged object

c.Objects having a net charge experience only electric force, not magnetic force

d.It is impossible to separate the North and South poles of a bar magnet

e.Electric forces decrease with decreasing distance from charges, but magnetic forces do not decrease with decreasing distance from magnets

An airplane pilot wishes to fly to his destination 500 mi due west, but the wind is blowing at 23.1 mi/hr toward 14.1° north of west. The speed of the plane relative to the air is 166.5 mi/hr. At what angle (south of west) must the pilot orient the plane in order to fly to his destination directly?

If the pilot orients the plane at that angle, what will be the speed of the plane relative to the ground?

A car’s initial velocity is 50.0 km/h in the direction 60.0° north of east, and its final velocity is 70.0 km/h in the direction 40.0° south of east. If the time period for this journey is 30.0 minutes, what is the magnitude of the car’s average acceleration? Group of answer choices

186 km/h/h

240 km/h/h

92.8 km/h/h

3.94 km/h/h

Which of the following statements are true?
True False  Magnetic field lines always start at a North and end at a South pole.
True False  When placing a dipole magnet into a magnetic field, it will be accelerated perpendicular to the field lines.
True False  The force on a moving charge is perpendicular to both the field and its velocity.
True False  The larger the charge of a moving particle, the more it will accelerate inside of a magnetic field.
