Answer:
The magnitude of each charge is
Explanation:
Suppose the two point charges are separated by 6 cm. The attractive force between them is 20 N.
We need to calculate the magnitude of each charge
Using formula of force
Where, q = charge
r = separation
Put the value into the formula
Hence, The magnitude of each charge is
The amount of heat needed to increase the temperature of a substance by
is given by
where m is the mass of the substance, Cs is its specific heat capacity and
is the increase of temperature.
If we re-arrange the formula, we get
And if we plug the data of the problem into the equation, we can find the specific heat capacity of the substance:
Answer:
A cell is the basic block of life and is always changing to fit its environment.
Explanation:
A cell is the basic founding block of a living organisms. In other words, a cell is the basic membrane unit which contains fundamental molecules of life. It is the cell that all living things are composed of.
The cell always changes with the surroundings and environment and it adapts to it. The cells requires a constant adjustments as the conditions inside and the outside the cells changes to keep a stable internal environment. Because the environment internally and externally is always changing, the cell continuously make adjustments to stay at or the near the set point.
