A runner is jogging in a straight line at a
Fiesta28 [93]

Answer:

Total distance traveled by bird is 10.5 km.

Explanation:

Given that,

Velocity of runner= 8.4 km/hr

Distance = 6.3 km

Velocity of bird = 42 km/hr

Suppose, How far does the bird travel?

We need to calculate the time of bird

Using formula of time

t=\dfrac{d}{v_{b}}

Put the value into the formula

t=\dfrac{6.3}{42}

t=0.15\ hr

We need to calculate the distance runner travels during time period

Using formula of distance

d=v_{r}\times t

d=8.4\times0.15

d=1.26\ km

We need to calculate the distance of runner to FL

Using distance

d'=6.3-1.26

d'=5.04\ km

We need to calculate the net closing speed between runner and bird

Using speed

v'=v_{r}+v_{b}

v'=8.4+42

v'=50.4\ km/hr

We need to calculate the time for runner and bird to meet

Using formula of time

t=\dfrac{d}{v'}

Put the value into the formula

t=\dfrac{5.04}{50.4}

t=0.1\ hr

We need to calculate the distance covered by runner

Using formula of distance

d=vt

Put the value into the formula

d=8.4\times0.1

d=0.84\ km

We need to calculate the distance covered by bird to runner

Using formula of distance

d=vt

Put the value into the formula

d=42\times0.1

d=4.2\ km

We need to calculate the total distance

Using distance

D=6.3+4.2

D=10.5\ km  

Hence, Total distance traveled by bird is 10.5 km.

Which changes of state do the labels represent? a: b: c:
VladimirAG [237]

A represents the so-called sublimation of state. represents the evaporation, a state change. C stands for melting, a change of state.

<h3>What does evaporation kid mean?</h3>

A liquid turns into a gas through evaporation. Water vapor is created when liquid water evaporation turns it into a gas. Water is helped to evaporate and return to the atmosphere by the heat of the sun. There, it creates a cloud and returns to being water in the form of vapor.

<h3>What exactly happens during evaporation?</h3>

Evaporation is the process by which liquid water transforms into gaseous water (water vapor). Water from the Earth's surface is carried into the atmosphere by evaporation. Evaporation occurs when heat energy causes the bonds holding the water molecules together to fall apart.
