400 km - 300 km = 100 km, since the dog stopped only 100 km away from where he had originally started out.
The length of the inclined plane is approximately 12 ft
The situation forms a right angle triangle.
<h3>Right triangle</h3>
Right triangle have one of its angle as 90 degrees.
Therefore,
The length of the inclined plane is the hypotenuse of the triangle. The length of the inclined plane can be found using trigonometric ratios.
height = 4 ft
angle(∅) = 19.45°
sin 19.45 = 4 / h
h = 4 / 0.33298412235
h = 12.0125847796
h = 12 ft
Therefore, the length of the inclined plane is approximately 12 ft

Answer: Internal energy changes that do not register on a thermometer are due to changes in the potential energy of the particles.
Explanation: a thermometer measures the temperature, which is a measure of the average kinetic energy of the particles.
The answer is "Density". defined as amount of matter per unit volume. It is also a measurement of how tightly matter is crammed together. Density is mass per unit volume. written as ρ = m/v. Greek letter ρ (rho). The derive unit for density is usually in Kg/m³.
