Answer:
The minimum speed of the box bottom of the incline so that it will reach the skier is 8.19 m/s.
Explanation:
It is given that,
Mass of the box, m = 2.2 kg
The box is inclined at an angle of 30 degrees
Vertical distance, d = 3.1 m
The coefficient of friction, 
Using the work energy theorem, the loss of kinetic energy is equal to the sum of gain in potential energy and the work done against friction.


W is the work done by the friction.







v = 8.19 m/s
So, the speed of the box is 8.19 m/s. Hence, this is the required solution.
The sun is a star (a giant ball of burning gases).
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:

Explanation:
Ohm's law states the relationship between voltage, resistance and current in an electrical circuit containing passive elements only:

where
V is the voltage supplied by the battery
R is the resistance of the circuit
I is the current
From the equation, we see that the voltage, V, is directly proportional to the current in the circuit, I.
