Which of these will have the same units of pressure is multiplied by area? Velocity time force or pressure
choli [55]

Considering the definition of pressure, force will have the same units of pressure is multiplied by area.

<h3>What is pressure</h3>

Pressure is defined as the force exerted per unit area.

In this way, for the same force, the pressure is inversely proportional to the surface: this means that, for the same force, the smaller the surface, the greater the pressure exerted and the more the body will be deformed.

That is, pressure is defined as the force exerted perpendicularly on a surface and is expressed mathematically as:

Pressure=\frac{Force}{Area}

In the International System of Units, the unit of pressure is the pascal (Pa). One pascal is the pressure exerted by a force of 1 N distributed over an area of ​​1 m².

Then, the definition of force can be expressed as:

Force= Pressure× Area

<h3>Summary</h3>

In summary, force will have the same units of pressure is multiplied by area.

A set of charged plates 0.00262 m apart has an electric field of 155 N/C between them. What is the potential difference between
mylen [45]

Answer: The potential difference between the plates = 0.4061V

Explanation:

Given that the

Electric field strength E = 155 N/C

Distance d = 0.00262 m

From the definition of electric field strength, is the ratio of potential difference V to the distance between the plates. That is

E = V/d

Substitute E and d into the above formula

155 = V/0.00262

Cross multiply

V = 155 × 0.00262

V = 0.4061 V

The potential difference between the plates is 0.4061 V

Determine the volume of a cube whose width is 32.1 cm. Round your answer to the correct number significant figures.
Romashka [77]

The volume of a cube is given by:

V=L^3

where L is the measure of each side (which corresponds to its width, since all sides of a cube are equal).

Plugging the data of the problem, L=32.1 cm, inside the equation, we find the volume:

V=L^3 =(32.1 cm)^3 =33076.2 cm^3

The following statements regarding the exhaust gas recirculation (EGR) valve are all correct except:
elixir [45]

Answer:

B. Some systems monitor EGR operation using a manifold absolute pressure (MAP) sensor.

Explanation:

The Manifold Absolute Pressure (MAP) sensor is a device used to measure absolute pressure inside the engine, it is used to calculate gas quantity needed to be injected into the cylinder and also for engine load input by the powertrain control module (PCM).

It is not used with the EGR as a monitor.
