NikAS [45]
Hi Gonnah,
W=qΔV
W= q(-70-130)
q of proton look it up and plug in and find out
it should be negative since you are doing work form greater potential to lower

When placed in a ________ solution, a cell will exhibit a net loss of water. the specific process by which the water leaves the
katen-ka-za [31]

The specific process by which the water leaves the cell is called <u>plasmolysis.</u>

<h3>What is plasmolysis?</h3>

Plasmolysis is the process in which the cell loses the water that is present inside it because the environment of the cells produces pressure to build up inside the cell. If a cell is present in a hypertonic solution means that solvent concentration is lower in the surrounding solution, then water comes out of the cell while on the other hand, if a cell is present in a hypotonic solution in which the solvent concentration is higher in the surrounding solution, then water goes inside of the cell. The movement of liquid inside or outside of the cell occurs due to the semi-permeable membrane of the cell.

So we can conclude that the specific process by which the water leaves the cell is called <u>plasmolysis.</u>

An object with a mass M = 250 g is on a plane inclined at 30º above the horizontal and is attached by a string to a mass m = 150
malfutka [58]

Answer:

0.495 m/s

Explanation:

T = tension force in the string connecting the two objects

M = Mass of the object on inclined plane = 250 g = 0.250 kg

m = Mass of the hanging object = 150 g = 0.150 kg

a = acceleration of each object

From the force diagram, force equation for the motion of the object on the inclined plane is given as

T - Mg Sin30 = Ma\\T = Mg Sin30 + Ma

From the force diagram, force equation for the motion of the hanging object on the inclined plane is given as

mg - T = ma\\T = mg - ma

Using the above two equations

Mg Sin30 + Ma = mg - ma

(0.250)(9.8) Sin30 + (0.250) a = (0.150) (9.8) - (0.150)a

a = 0.6125 ms^{-2}

h = height dropped by the hanging object = 10 cm = 0.10 m

v = Speed gained by the object

Speed gained by the object can be given as

v = sqrt(2ah)\\v = sqrt(2(0.6125)(0.20))\\v = 0.495 ms^{-1}
