<h3>What is a heating curve?</h3>
The heating curve is a representation of temperature change for a body with time as shown on cartesian axes.
The point A represents the steady increase in the temperature of the solid. The point B shows the point of fusion, at this point, the solid is transformed into liquid. The point C shows the temperature rise with time as the liquid is heated. The point D shows the process of vaporization which converts the liquid to gas. The point E shows when the substance now exists in the gas phase.

Answer:
The ball reaches a maximum height of 196ft above the point where it was launched.
Explanation:
Please see attachment below.
Answer:
Correct answer: W = 2,240 J
Explanation:
Given:
m = 70 kg
V₁ = 6 m/s
V₂ = 10 m/s
W = ?
Work is a measure of change in this case of kinetic energy:
W = ΔE = (m V₂²)/ 2 - (m V₁²)/ 2 = (m / 2) · (V₂² - V₁²)
W = (70 / 2) · (10² - 6²) = 35 · (100 - 36) = 35 · 64 = 2,240 J
W = 2,240 J

I believe the answer is two convex lenses. A compound microscope has two systems of lenses for greater magnification, the ocular, or eyepiece lens that one looks into and the objective lens, or the lens closest to the object. Both the ocular lens and the objective lens are convex lens.
