Which of these is most likely to lead directly to a black market?a. a supply shock
c. rationing
b. a price floor
d. equilibrium

Answers

Answer 1

Answer:

Answer:

c. rationing

Explanation:

Which is an example of a good whose price goes down because of improvements in technology? Why did Communist governments use a command economic system for many years? ... Quantity demanded will exceed quantity supplied, so the price will drop. Excess supply means that producers will make less of the good.

Answer 2

Answer: I would say it's rationing: if people are only allowed a certain number of something (let's say: bottles of cooking oil), then the people who are entitled to is (as all are) but don't need is as much are likely to try to make profit by trying to sell it on a black market.

What would be the result of an alpha particle coming into a magnetic field?A) The alpha particle will stop moving.
B) The alpha particle will reverse its direction.
C) The alpha particle will be deflected in a curve path.
Eliminate
D) The alpha particle will continue to travel in a straight line.

Answers

Answer: C) The alpha particle will be deflected in a curve path.

Explanation:

Alpha particle carries +2 charge. It is a Helium ion: He⁺²

When any charged particle enters a magnetic field, it experiences a magnetic force perpendicular to direction of the velocity of the particle and the direction of the magnetic field. Thus, the alpha particle moves in a circular path.

Hence, the correct answer is: The result of an alpha particle coming into a magnetic field is C) The alpha particle will be deflected in a curve path.

The right answer for the question that is being asked and shown above is that: "C) The alpha particle will be deflected in a curve path. " the result of an alpha particle coming into a magnetic field is that C) The alpha particle will be deflected in a curve path.

you measure that it takes 0.75 seconds for a leaf to fall from a tree to the ground. the leaf experiences air resistance as it falls. if there were no air resistance, how long would it take the leaf to fall?

Answers

There's not enough information given in the problem to calculate that answer.

A leaf falling from a tree on Earth, a sheet of printer paper falling off the back
of a truck on Venus, and a steel ball sinking through a bucket of Scotch whiskey
on Mars, might all reach the bottom in 0.75 second. The time it would take each
of them to fall the same distance through a vacuum in the same place would be
different, and the 0.75 second is not enough to enable you derive it ... even if
you did know the acceleration of gravity in each place. All you can say is that
without resistance, it would fall faster, and hit bottom in less than 0.75 second.

Answer:

less than 0.75 seconds

Explanation:

A hair curling iron uses 13 watts of power. how long must it operate to do 1,040 joules of work?

Answers

Knowing the solution to the 4-watt night light, you ought to be able to do this one on your own. But 5 points is 5 points, so here we go:

1 watt = 1 joule/second .

(1,040 joule) / (13 joule/second)

= (1,040 / 13) (second)

= 80 seconds .

Power of Watt = Energy in Joules / Time period in seconds

13 watts = 1040 joules / time in seconds
time in seconds = 1040 joules / 13 watts
time in seconds = 80 seconds

It must operate for 80 seconds to do 1,040 joules of work.

Why do the densities of most substances decrease with an increase in temperature?

Answers

because density is related to activity of particles, the higher the activity level (the faster they're moving, and distance between them) the less dense they are. for example, H2O in a solid the particles are close together with minimum movement and it exists as ice, but when heat is applied the particles become more active and move more decreasing the density becoming liquid water, then when excessive heat is applied the same occurs and it becomes gas steam

Which statement best describes the superposition principle?A. If two in-phase waves arrive simultaneously at a point, their amplitudes add up.
B. If two out-of-phase waves arrive simultaneously at a point, their amplitudes add up.
C. If two in-phase waves arrive at a point one after another, their amplitudes add up.
D. If two out-of-phase waves arrive at a point one after the other, their amplitudes adds up

Answers

C. If two in-phase waves arrive at a point one after another, their amplitudes add up.

Final answer:

The superposition principle states that when two in-phase waves arrive simultaneously at a point, their amplitudes add up.

Explanation:

The correct statement that describes the superposition principle is option A: If two in-phase waves arrive simultaneously at a point, their amplitudes add up. In-phase waves have the same frequency, wavelength, and direction. When two in-phase waves meet, the amplitude of the resultant wave is the sum of the individual amplitudes.
