Answer:
Scalar, a physical quantity that is completely described by its magnitude; examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors.
Explanation:
Scalar quantities give a magnitude, while vector quantities give a magnitude and a direction. The answer will be a measurement that does not change, regardless of the direction of action. Displacement is a measure of length in a given direction; distance is the scalar version of displacement. ... Mass is a scalar quantity.
examples of scalar quantities are mass, speed, distance, time, energy, density, volume, temperature, distance, work and so on
Completed question:Suppose one speaker is driven at 570 Hz and the other at 554 Hz. What is the beat frequency in Hz? The average frequency in Hz?
Answer:
Beat frequency= 16Hz
Average frequency = 562Hz
Explanation:
Beat frequency f = f2-f1
Where f2 is frequency of source with higher frequency
f1 is frequency of source with lower frequency
f1= 554Hz, f2= 570Hz
beat frequency (f) = 570 -554
= 16Hz
Average frequency =
=
Answer:
Acceleration (a) is defined as the rate of change of velocity. Velocity is a vector quantity, and therefore acceleration is also a vector quantity. The SI unit of acceleration is metres/second2 (m/s2).
You can thank me if this answer helps. The energy coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests,even before dinosaurs!
