The central and inscribed angle theorem is used to solve angles and arc measure in a circle.
<h3>What is the Central and Inscribed Angles Theorem?</h3>
The theorem shows the relationship of the measures of an inscribed angle, central angle, and their intercepted arc.
It states that:
- central angle measure = measure of inscribed angle.
- inscribed angle measure = 1/2(measure of inscribed angle)
Therefore, the central and inscribed angle theorem is used to solve angles and arc measure in a circle.

At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is
∑ F = 450 N - (0.75 kg) g = (0.75 kg) a
where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of
a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²
Then its maximum tangential speed v is such that
a = v² / (1.0 m)
⇒ v = √((1.0 m) a) ≈ 25 m/s
<h3 /><h3>How do rock types contribute to the rate of weathering?</h3>
<h3>Answer
<em>;</em><em> </em><em> </em><em>Certain types of rock are very resistant to weathering. Igneous rocks, especially intrusive igneous rocks such as granite, weather slowly because it is hard for water to penetrate them. Other types of rock, such as limestone, are easily weathered because they dissolve in weak acids.</em></h3>
