Answer:

One may assume that the planet radiates energy like a blackbody at some temperature according to the Stefan–Boltzmann law. Thermal equilibrium exists when the power supplied by the star is equal to the power emitted by the planet. The temperature at which this balance occurs is the planetary equilibrium temperature.

The answer is : <span>A model could be used to test his design in a lab. </span>Marty is developing a new way to heat an airplane's windshield to prevent it from accumulating ice when in flight. A thin layer of clear, conductive material is injected between two layers of thick windshield plastic. A very small electric current is run through the inner material to keep the plastic layers warm. The model that could help Marty develop his design is the kind of model that could be used to test his design in a lab.

A car is stationary. It accelerates at 0.8 ms^2 for 10 s and then at 0.4 ms^2 for a further 10 s. Use the equations of motion to

Answer:

The final displacement of the car is 140 meters.

Explanation:

The final displacement of the car ( $s$ ), in meters, is the sum of the change in displacement associated with each part of the journey, which is derived from the following kinematic formulas:

$s = s_{1} + s_{2}$ (1)

$s_{1} = \frac{1}{2}\cdot a_{1}\cdot t_{1}^{2}$ (2)

$v_{o,2} = a_{1}\cdot t_{1}$ (3)

$s_{2} = v_{o,2} + \frac{1}{2}\cdot a_{2}\cdot t_{2}^{2}$ (4)

Where:

$s_{1}$ - Traveled distance of the first part, in meters.

$s_{2}$ - Traveled distance of the second part, in meters.

$a_{1}$ - Acceleration in the first part, in meters per square second.

$a_{2}$ - Acceleration in the second part, in meters per square second.

$v_{o,2}$ - Initial speed of the car in the second part, in meters per second.

$t_{1}$ - Time taken in the first part, in seconds.

$t_{2}$ - Time taken in the second part, in seconds.

If we know that $a_{1} = 0.8\,\frac{m}{s^{2}}$ , $t_{1} = 10\,s$ , $a_{2} = 0.4\,\frac{m}{s^{2}}$ and $t_{2} = 10\,s$ , then the distance traveled by the car is:
