A rotating disc supplied with constant power where the relationship of the angular velocity of the disc and the number of rotations made by the disc is governed by Newton's second law for rotation. This law is specially made for rotating bodies which is extracted from Newton's second law of motion.

<h3>Answer;</h3>
<u>It would make the lens stronger. </u>
<h3>Explanation;</h3>
- The focal length is the distance between the optical center or the center of the lens to the focal point of a convex or concave lens.
- The power of the convex lens is lens ability to undertake refraction or bend light. It is given as the reciprocal of focal length.
- Power of the lens = 1/ f; therefore the smaller the focal length the higher the power and the larger the focal length the lower the power.
- Thus; decreasing the focal length of a convex lens makes the lens stronger.
Answer:
This is because animals do not need to store as much water as plants.
Explanation:
Animals generally have smaller vacuoles than plants. Plants have large vacuoles that can occupy a large portion of their cell (up to 30 percent). The major function of the vacuole is to store water and maintain cell turgidity and pressure against the cell wall.
Animals on the other hand do not have a rigid cell wall, rather, they have a flexible cell membrane. As a result of this, they do not need to store water in vacuoles.
