Answer:

 F = 0

Explanation:

Newton's second law is

         F = ma

As in this case the two blocks move with constant speed, it implies that the acceleration is zero, therefore the force applied to the system is zero

       F = 0

What is the Voltage of a circuit that has a resistance of 50 and a current of 2 A?
Nutka1998 [239]

Answer:

It's actually 100V

Explanation:

To answer this, you'd need to use Ohm's law, which states that Voltage is equivalent to the product of Current and Resistance (V=IR).

V = 50 × 2

V = 100

Therefore the voltage is a 100V.

None of the answers you have listed match this though, so I'm guessing it either must be typo or the question itself is wrong.

What is the relationship between amplitude and volume?
MrRissso [65]

Answer:

Explanation:

The sound moves in the form of waves. The amplitude is the distance between the highest and the lowest point of a wave.  In this way the amplitude indicates the amount of energy that a sound signal contains.

Intensity is the amount of acoustic energy that a sound contains. Intensity is measured in decibels. Volume is a measure of the energy that a signal carries, being a magnitude of intensity.

In this way it is possible to say that the energy of a signal is closely related to its amplitude, but its development over time is also important.

The tone or height is the quality that distinguishes between a high or low sound and a low or high sound.

What are the types of realistic fiction?.
Daniel [21]

The types of realistic fiction:<u> are </u><u>historical </u><u>and </u><u>contemporary </u><u>fiction.</u>

Bond [772]

Lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students. Option D is correct.

<h3>What is a Transverse wave?</h3>
  • The wave in which the oscillation of particles is is perpendicular to the direction of energy transfer.

  • The students can make a transverse wave by raising their hands up and then down, one student at a time.

  • The raised hand represents the oscillation of particles while the sequence of the raising hand represents the direction of energy transfer.

Therefore, lifting hands and the down by one student at a time best describe the presentation of the transverse wave by students.
