Answer:
30 celsius
Explanation:
30 celsius = 86 fahrenheit
The speed of the car is 75 km/h
<h3>Further explanation</h3>
These are the formulas that we have to remember before solving the problem.
Speed is the rate of change of distance.
<em>v = speed ( m/s )</em>
<em>d = distance ( m )</em>
<em>t = time ( s )</em>
Acceleration is the rate of change of velocity.
<em>a = acceleration ( m/s² )</em>
<em>Δv = change in speed ( m/s )</em>
<em>t = time ( s )</em>
Let us now tackle the problem!
<u>Given:</u>
distance = d = 150 km
time taken = t = 7200 s = 2 hours
<u>Unknown:</u>
velocity = v = ?
<u>Solution:</u>
The acceleration of the car is 0 m/s² because it travels with constant speed.
We could also plot the distance vs time graph as shown in the attachment.

What has changed is the velocity. This is happen because :
- Velocity is a vector quantity that is easily affected by changes in the direction of motion.
- The presence of this displacement vector causes the resultant velocity to be 15√2 m/s.
<h3>Explanation</h3>
Hi ! Here I will discuss about velocity and speed. velocity is different from speed. Velocity depends on displacement (movement relative to the starting point) divided by the value of time. On the other hand, speed depends only on distance (how far the object is moving) regardless of the starting point of the movement. Therefore, velocity is called a vector quantity (a value that is easily influenced by direction), while speed is called a scalar quantity because it does not care about direction.
<h3>Proof </h3>
Why do I say there that the resultant velocity is 15√2 m/s ? This is because there is a double direction that makes it necessary to calculate the resultant using the formula:
>> = 90°

Answer:
Pleural cavity
Explanation:
Pleural cavity is thin fluid filled space that surrounds the lungs and provide lubrication during the expansion and contraction. So if the bullet enters the left lung then it has been entered in the pleural cavity.
Pericardial cavity contains heart and other blood vessals so it is not the right option. Mediastinum is the area between the lungs that contains the heart parts so it not the right option too. Then comes the vertebral canal also known as spinal cord so it has nothing to do with the lungs. Hence the correct option is Pleural cavity.
