Answer;
The above statement is False
Explanation;
- Saturated fats are types of fats that lacks double bonds or triple bonds between any two carbon atoms because they are saturated with hydrogen molecules.
- Saturated fats should be limited at all costs. Eating foods with saturated fats raises the amount of cholesterol in the blood which may increase the risk of heart disease and stroke.
- Avocados contain over 75% fat that is unsaturated or the good fats, and the rest are unsaturated or the bad fats. Therefore, saturated fats found in avocados are not good and should be limited.
Saturated fats that are found in avocados are good and should not be limited. True False

The period is 5 s, and the frequency is 5 Hz.
Answers
The period is 1/5 second, and the frequency is 5 Hz.
Explanation:
Let's start by reviewing some definitions about waves:
- The period of a wave is the time taken for the wave to make one complete cycle. It is indicated with T and it is measured in seconds (s)
- The frequency of a wave is the number of complete cycles made by the wave in one second. It is indicated with f and it is measured in Hertz (Hz). It is equal to the reciprocal of the period:
where f is the frequency and T is the period.
In this problem, we have a wave that passes a given point five time per second. This means that the number of oscillations per second is five, and so its frequency is:
It follows than the period of the wave is:
Therefore, the correct statement is
The period is 1/5 second, and the frequency is 5 Hz.

CALCULATION:
As per the question, the force applied on the block F = 40 N.
The distance travelled by the block S = 10 m.
We are asked to calculate the work done by the block.
The work done by a body under a force F is calculated as -
Work done W =
=
Here, is the angle between force and displacement.
If , then work done W =
= FS. [ cos0 = 1]
Hence, the work done by the block W = FS
= 40 N × 10 m
= 400 Joule. [ans]
Here, Joule is the unit of work.
Hence, the work done by the block s 400 Joule.

Answer:
There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another. ... Friction is useful for charging insulators, which are materials that aren't good conductors.
