The distance travelled by the car after the first four hours of the trip is 370 km and the average speed for the first four hours of the trip is 92.5 kmph

v ( t ) = d ( t ) / t

v ( t ) = Velocity with respect to time

d ( t ) = Distance with respect to time

t = Time

For the first four hours, the following details are taken from the graph shown.

d ( 4 ) = 370 km

t = 4 hr

v ( 4 ) = 370 / 4

v ( 4 ) = 92.5 kmph

Average velocity can also be calculated using the formula V = ( u + v ) / 2 if the initial and final velocities are given. u represents initial velocity and v represents the final velocity.

Therefore,

Distance travelled in first 4 hours = 370 km

Average speed in first four hours = 92.5 kmph

To know more about average velocity

Explaining how caring capacity influences the number of organisms.

An ecosystem can only sustain so many organisms. That limit would be its <span>carrying capacity. If the population goes above that number then other factors will cause the population to crash and then rebound to a constant level. </span>

Answer:

$4.58\times 10^{14}Hz$ $5.825\times 10^{14}Hz$ $6.31\times 10^{14}Hz$

Explanation:

We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as $v=\nu \lambda$ where v is speed of light $\nu$ is frequency of light $\lambda$ is wavelength of light

In first case we have given λ=655 nm

so using formula $v=\nu \lambda$

$3\times 10^8=655\times 10^{-9}\times \nu$

$\nu =4.58\times 10^{14}$ Hz

In second case we have wavelength 515 nm so by using above formula

$3\times 10^8=515\times 10^{-9}\times \nu$

$\nu =5.825\times 10^{14}\ Hz$

In third case we have wavelength 475 nm

so $3\times 10^8=475\times 10^{-9}\times \nu$

$\nu =6.31\times 10^{14}Hz$

Answer: A balloon provides a simple example of how a rocket engine works. The air trapped inside the balloon pushes out the open end, causing the balloon to move forward. The force of the air escaping is the "action"; the movement of the balloon forward is the "reaction" predicted by Newton's Third Law of Motion.
