Intensity. They relate the intensity of a pressure wave to a normal or standard pressure
Explanation:
Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties:
Frequency, or its inverse, wavelength.
Amplitude, sound pressure or Intensity.
Speed of sound.
Direction.
Answer:
θ = 18.3°
Explanation:
The angle can be found by using the formula for the range of projectile motion:
where,
R = Horizontal Range = 8.75 m
u = launch speed = 12 m/s
g = acceleration due to gravity = 9.81 m/s²
θ = launch angle = ?
Therefore,
θ = 18.3°
Since this angle is less than 45°. Therefore, it is the smaller of the two possible angles an dit is the correct answer:
<u>θ = 18.3°</u>
The volume of the jet fuel is 1.213 x 10⁵ cm³.
<h3>What is density?</h3>
Density is a physical property that measures the ratio of mass to volume occupied by an object.
Density = mass/volume
Volume = mass/density
<h3> Volume of the jet fuel</h3>
The volume of the jet fuel is calculated as follows;
Volume = (97500 g)/(0.804 g/cm³)
Volume = 1.213 x 10⁵ cm³
Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.
