Why does a pendulum have periodic motion?

Physics
1 answer:
Igoryamba3 years ago
7 0
A, B, and C are all incorrect because they are talking about springs. I'm assuming you're talking about a 2 dimensional, side to side pendulum. In that case, the answer is D because as the pendulum goes up from one side, gravity accelerates it downward until it swings to the other side. If you're not talking about this type of pendulum, leave a comment and ill come back.

Newton’s third law of motion says that for every action there is a(n)  and opposite reaction​
lyudmila [28]

Answer:

Newton's third law of motion says that for every action there is an equal and opposite reaction.

Explanation:

This law explains that when two bodies interact with one another, two forces facilitates this process.These forces are opposite is action but equal in magnitude.For example, when sitting on a coach, the body exerts force on the coach downwards and the coach exerts an upward force on the body.These two forces are the action and reaction forces.

What is the total capacitance in units of mF, of the two capacitors connected in series, as shown in the diagram, when C1 = 45 m
elena-14-01-66 [18.8K]

Answer:

16.7 mF

Explanation:

The total capacitance of two capacitors connected in series is given by the formula:

\frac{1}{C}=\frac{1}{C_1}+\frac{1}{C_2}

in our problem, we have:

C1 = 45 mF is the capacitance of the first capacitor

C2 = 26 mF is the capacitance of the second capacitor

Substituting into the equation, we find:

\frac{1}{C}=\frac{1}{45 mF}+\frac{1}{26 mF}=0.06 mF^{-1}\\C=\frac{1}{0.06 mF^{-1}}=16.7 mF
