Answer:

Because liquid solutions cannot penetrate the sheet, while gases can penetrate.

Explanation:

The paper is called acid when the internal bonding adding specific chemicals to the fibrous suspension in order to control the penetration of liquids in the sheet is carried out in an acid medium (pH = 4.0 to 5.0) with the addition of glue to the pitch-based, aluminum sulfate and, generally, kaolin as a mineral filler, just to name the main additives. Liquid solutions have difficulties in penetrating the leaves, for this reason, these solutions are not the best option to treat acid paper and it is preferable to use gases.

How do you tell a stars life expectancy based on an hr diagram?
e-lub [12.9K]
The X-axis of the H-R Diagram indicates the star's surface temperature in degrees Kelvin.  The Y-axis, on the other hand, indicates luminosity, or brightness.

Main sequence refers to a roughly diagonal, slightly S-curved line stretching between the upper-left and lower-right corners on which main sequence stars chart. They maintain a predictable relationship between luminosity and temperature: the brighter, the hotter. The upper-right quadrant of the H-R diagram is home to newly discovered red giants while the lower-left quadrant of the H-R Diagram belongs almost exclusively to white dwarfs.

scoundrel [369]

Answer:

All the three quantities will have non zero joules.

Explanation:

At the initial position of rest the system will have only gravitational potential energy while the other 2 quantities will be zero.

when the system reaches a height (y-h) only kinetic energy will be zero while the other 2 quantities will be non zero

At the position of (y-h/2) all the 3 quantities will be non zero.

Reika [66]

Answer:

7.401 * 10^(-15) N

Explanation:

30 electrons will have a charge:

30 * -1.6022 * 10^(-19) C

= - 4.806 * 10^(-18) C

The relationship between electric field and electric force is:

E = F/q

This means that force, F, is

|F| = |E|*|q|

|F| = |1540| * |-4.806 * 10^(-18)|

|F| = |-7401.24 * 10^(-18)|

|F| = 7.401 * 10^(-15) N
