Technician A says that the oil pan on a two-stroke engine holds more oil than a typical four-stroke engine. Technician B says th

Arturiano [62]

Answer:

Technician A is right, because the lubrication system in a two-stroke engine requires mixing with the fuel, therefore oil is constantly burned, while a 4-stroke engine has a separate lubrication system.

Technician B is wrong, usually the 2-stroke engines are small and the cooling system is that the cylinder container is constructed with a geometry that allows to increase the area of heat transfer called fins, this allows to release heat quickly .

What is a volt as applied in physics

Alexus [3.1K]

Answer:

The answer is below

Explanation:

Volt in physics is a term that is used to describe the unit of both electrical potential difference and electromotive force. In other words, it is a unit of measuring the voltage between two points. It is represented as "V".

The formula for Voltage is V=IR

Where V= Voltage, I = Current and R = Resistance.

4. A family leaves from New York City and is flying to Los Angles which is 2800mi away. It takes

Blizzard [7]

The average speed of the whole travel is equal to <u>400 mph</u>.

Why?

From the statement, we know that whole travel is divided into three parts. For the first part (traveling from New York to Chicago), we have that it was 3.25 hours and the covered distance was half of the total distance (1400mi). For the second part, we have that it was 1 hour (layover time), and the covered no distance. For the third part (traveling from Chicago to Los Angeles), we have that it was 2.75 hours, and it took the other half of the total distance (1400mi).

We can calculate the average speed of the whol travel using the following formula:

$AverageSpeed=\frac{distance_{1}+distance_{2}+distance_{3}}{time_{1}+time{2}+time_{3}}$

Now, substituting and calculating, we have:

$AverageSpeed=\frac{1400mi+0mi+1400mi}{3.25h+1h+2.75h}$

$AverageSpeed=\frac{2800mi}{7h}=400mph$

Hence, we have the average speed of the whole travel is equal to 400 mph.

Have a nice day!
