Give a specific example of a scalar or vector quantity. Explain why thus type of quantity is used to describe this event.
dlinn [17]

Example of scalar: speed. Example of vector: velocity

Explanation:

In physics, there are two types of quantities:

- Scalar: a scalar quantity is a quantity having only magnitude, so it is just a number followed by a unit. Examples of scalar quantities in physics are:

Mass

Time

Speed

- Vector: a vector quantity is a quantity having both a magnitude and a direction. Examples of vector quantities in physics are:

Force

Acceleration

Velocity

The two types of quantities can be used in the same event, but in a different way. One of the most common example is the difference between speed and velocity.

In fact, let's consider an object moving in a uniform circular motion: it means that it is moving in a circle at a constant speed. The speed of the object measures only how fast the object is moving, but without telling anything about its direction of motion. The velocity, viceversa, also takes into account the direction of motion, and exactly for this reason, the velocity in a uniform circular motion is not constant, because the direction (it is a vector) is constantly changing. So, in a uniform circular motion, the speed is constant but the velocity is not.

A mobile phone is 35% efficient. Over half an hour 11 kJ of energy is transferred to the phone.
kramer
<h3><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u></h3>

  • Energy Transferre=11KJ
  • Efficiency=35%
<h3>☆Usefully transferred energy:-</h3>

\\ \sf\longmapsto 35\%\:of 11

\\ \sf\longmapsto 35\%\times 11

\\ \sf\longmapsto \dfrac{35}{100}\times 11

\\ \sf\longmapsto \dfrac{385}{100}

\\ \sf\longmapsto 3.85KJ

\\ \sf\longmapsto 3850J

Choose the definition of: Kinesics
pav-90 [236]
<span>Kinesics is the study of the interpretation body motion communication such as facial expressions and gestures.   It does not include the verbal communication because you can communicate through words. Kinesics is a nonverbal communication that does not involve words. Example of this is when you are in a different country in which you do not know how to speak their native language. To understand their feelings, you don’t listen to their words but you observe their actions and facial structure when communicating. So the answer is letter A.</span>
