<h3>Answer;</h3>

D. Velocity

<h3>Explanation;</h3>

Velocity is the rate of change of displacement. It is given by dividing the displacement covered by the time taken.
That is; Velocity = Displacement/time
Therefore if two individuals took the same time to cover the same distance, then it means both will have the same velocity.

Question

The density of a material is constant and it is given by the ratio of the mass to the volume of the material

The mass of the liquid and the full bottle ae

The mass of the liquid is 450 g

The mass of the filled bottle is 530 grams

The reason the above values are correct are as follows:

The given parameters are;

Volume of the bottle, V = Half litre

Mass of the bottle, $m_b$ = 80 g

The volume of liquid in the bottle when filled, V = 500 cm³

The density of the olive oil with which the bottle is filled, ρ = 0.9 g/cm³

a. Required:

To calculate the mass of oil in the bottle

Solution:

The volume of oil in the bottle when the bottle is filled, V = 500 cm³

$Density, \ \rho = \dfrac{Mass}{Volume} = \dfrac{m}{V}$

The mass of the liquid, m = ρ × V

∴ m = 0.9 g/cm³ × 500 cm³ = 450 g

The mass of the liquid, m = 450 g

b. The mass of the oil in the bottle, m = grams

The mass of the full bottle, $m_{filled}$ = m + $m_b$

∴ $m_{filled}$ = 450 g + 80 g = 530 g

The mass of the full bottle, $m_{filled}$ = 530 grams

Which are examples of a medium? water and air amplitude and wavelength crests and troughs compressions and rarefactions

umka21 [38]

Answer:

water and air

Explanation:

A wave is a transmission of a disturbance from one point or the source to another point.
Transmission of a wave occurs through a material medium or a vacuum. Therefore a medium is the material through which a wave travels through.
The medium may be in gaseous form, slid form or liquid form. Therefore water and air are example of medium of transmission of a wave.

What happen to the frequency of a sound wave as you change the pitch?

steposvetlana [31]

The "pitch" of a sound is the impression your brain forms
that corresponds to the frequency of the sound wave.

When the frequency is high, your brain says "high pitch".

When the frequency is low, your brain says "low pitch".

An athlete executing a long jump leaves the ground at a 28.0º angle and travels 7.80 m. (A) What was the takeoff speed?

Naddika [18.5K]

Answer:

9.6 m/s

Explanation:

Angle of projection, θ = 28°

Horizontal distance, R = 7.8 m

Let the velocity of projection is given by u.

The formula used to find the velocity of projection is given by

$R=\frac{u^{2}Sin2\theta }{g}$
