Answer:
0.163 s
Explanation:
Appying,
P = mgh/t................ Equation 1
Where P = power of the motor, m = mass of the suitcase, h = vertical distance, t = time, g = acceleration due to gravity.
make t the subject of the equation,
t = mgh/P................ Equation 2
Given: m = 20 kg, h = 50 cm = 0.5 m, P = 0.6 kW = 600 W
Constant: g = 9.8 m/s²
Substitute these values into equation 2
t = (20×0.5×9.8)/600
t = 0.163 s
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>

Answer:
Yeah it's ok I think. Also, I can't see the answer you gave so maybe updating the question would be nice.
Answer:
Five: B
Ten: A
Explanation:
Five
An alpha decay looks like this.
So whatever is produced must have a mass of 4 less than 234 and a number on the periodic table of 2 less than 92. In other words, B has a mass of 230 and a number on the periodic table of 90.
The answer should be Thorium which is B.
Ten
There is actually not enough information to do 10. You get it by making an assumption and seeing if it works.
In general a beta decay can (the most common one ) look like this.
Is there anything that looks like that?
The weight stays the same (234) and the atomic number of the mother element (on the left) is 1 lower than the given chemical on the right.
The answer is Thorium A
Beta decays are very tricky. Be very careful how you handle them. One of three items can be what is decayed. I have assumed it was an electron, but there are two other possibilities. I won't confuse you by adding them. Just be aware that they exist.
