As an object sinks in a fluid, the buoyant force ____.a. increases
c. remains the same
b. decrease
d. depends on the shape

Answers

Answer 1
Answer: Beginning when the bottom of the object first touches the water,
and as it descends and more and more of it goes under, the
buoyant force on it increases during that time.

As soon as the object is completely underwater, it doesn't matter
how deep under it is, the buoyant force on it remains the same.

Answer 2
Answer:

As an object sinks in a fluid, the buoyant force decrease.

What is an example of a series circuit

Answers

Answer:

Explanation

The most famous and common example is Christmas tree lights. You can't tell easily by looking at them whether they are in series or parallel. But you sure know the difference when one of them burns out. When that happens, the whole string goes dead. No matter what you do (other than find out which bulb burned out) will not fix the problem.

Another example is anything that is temperature controlled. For example a furnace is controlled by a thermostat. When the room temperature reaches a certain point, the thermostat is constructed in a certain way so that it forms an open circuit and no current can flow through it. The furnace motor turns off and the furnace stops pumping hot air into a room.

The force of air particles over an area is?

Answers

Answer;

Air pressure

Explanation;

  • Pressure is the force that is applied over a unit of area. Air pressure is the weight of air molecules pressing down on the Earth. It is the force exerted by air particles on the earth's surface.
  • The column of air extends to the top of the atmosphere.  As one move up increasing the altitude, the air pressure decreases since the air column is reduced.
That's the "air pressure" everywhere on that area.

Objects that have value in themselves and that are also used as money is the definition for _____.a. commodity money
b. representative money
c. fiat money
d. money

Answers

Answer: The correct answer for the blank is- a. commodity money.


Commodity money can be described as a form of currency, which has an intrinsic value ( that is value of its own) as well as value (in the form of money) in their use.

For Example- gold, silver, grains serve as commodity money.

   Objects that have value in themselves and that are also used as money is the definition for  commodity money. Hope this helped :)

When discussing discordant and harmonious sound waves, which statement is false? A. Both types of waves are the result of component waves with different frequencies. B. Knowing the frequencies of the original waves is useful in determining if the result will be discordant or harmonious. C. Low ratios of the frequencies of the original and resultant waves indicate discordant waves. D. If the original waves combine to form irregular displacements of air, the sound will be discordant.

Answers

Correct answer choice is :


C) Low ratios of the frequencies of the original and resultant waves indicate discordant waves.


Explanation:


The sound is created when something vibrates. The vibrating body makes the means around it to vibrate. Vibrations in the air are described going longitudinal waves, which we can hear. Sound waves consist of regions of high and low pressure named compressions and rarefactions. The left ventricle will ultimately lose as depolarization opens from the right ventricle, but the stay in conduction effects in a wide QRS system. In the appearance of LBBB, the T wave should be discordant or diverted opposite the final deflection of the QRS system.

In which type of wave do the particles in a medium move perpendicular to the direction that the wave moves? A.transverse waves

B.ocean waves

C.surface waves

D.longitudinal waves

Answers

This type of wave is a transverse wave. Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
