evablogger [386]

Answer:

\boxed {\sf Physical}

Explanation:

There are two main kinds of properties: chemical and physical.

Chemical properties, like the name suggests, have to be observed by changing the chemical composition.

That leaves <u>physical properties.</u> They can be measured without any chemical composition changes.

Some examples include: color, odor, mass, density, and volume. All can be measured with just the senses or measuring tools and no composition alterations are needed.

AURORKA [14]

Answer:

the pressure in the pipe in the case when there is no net force on the car is  81,726 N/m^2

Explanation:

a. The computation of the pressure in the pipe in the case when there is no net force on the car is shown below

As we know that

Pressure = F ÷ area

Also

F = mg

Now

= (1500 × 9.8) ÷π (0.24)^2

= 81,726 N/m^2

Hence, the pressure in the pipe in the case when there is no net force on the car is  81,726 N/m^2
