Salt water is not an example of suspension as salt dissolves in water and combines with it rather than float in the water.
Pat realized that law is scientific fact, while theory is an educated guess.
Answer:
Look at explanation
Explanation:
One of the easier ways to define wave motion is the continuous movement of particles. When we have a rope for example and whip it, the first particle bumps into the second one then into the third and so on and so forth until the end of the rope. Particles can only move up and down or left and right and the vibration caused by each particle is what sets off the wave motion.

Explanation:
A sound wave in a steel rail has a frequency of 620 Hz and a wavelength of 10.5 m. What is the speed of sound in steel? U f = ? S f = 3 x 108 m/s) / 0.06 m 14 so it will be 14
Answer:
Explained below
Explanation:
- Friction is the force that opposes the motion between two or more objects/surfaces in contact with each other.
- On an inclined plane, the coefficient of static friction is given by the relation;
μ = F_max/F_n
Where;
F_max is maximum frictional force before slip = mg sin θ
F_n is normal force = mg cos θ
Thus;
μ = mg sin θ/mg cos θ
μ = tan θ
