The physical properties of the bowling ball is that it is hard, smooth and very dense.
<h3>What are physical properties?</h3>
Physical properties are those properties which are easily observable and which involve only physical changes in a substance.
A bowling ball is a solid.
The physical properties of bowling ball include:
- density- it has high density
- texture- it is smooth
- hardness - it is hard
Therefore, the physical properties of the bowling ball is that it is hard, smooth and has high density.

Refraction is the bending of a wave when it enters a medium where its speed is different. This phenomenon is explained by the conservation of energy and conservation of momentum.
Law of Conservation of energy states the total energy of an isolated system remains constant.
law of conservation of momentum states that in a closed system the total momentum is constant.
<span>In refraction, when a medium changes, the phase velocity also changes but its frequency does not; it remains constant. </span>
Answer:
Reading a Graduated Cylinder
Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.....
hope it helps....
