Answer:
Equivalent resistance: 13.589 Ω
Explanation:
R series = R1 + R2 + R3 ...
![\frac{1}{R_{eq} } = \frac{1}{R1} +\frac{1}{R2} +\frac{1}{R3} ...](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Beq%7D%20%7D%20%3D%20%5Cfrac%7B1%7D%7BR1%7D%20%2B%5Cfrac%7B1%7D%7BR2%7D%20%2B%5Cfrac%7B1%7D%7BR3%7D%20...)
Find the equivalent resistance of the right branch of the circuit:
![R_{eq} = R_{2} +R_{3} \\R_{eq} = 20.7 + 25.8 = 46.5 ohms](https://tex.z-dn.net/?f=R_%7Beq%7D%20%20%3D%20R_%7B2%7D%20%2BR_%7B3%7D%20%5C%5CR_%7Beq%7D%20%3D%2020.7%20%2B%2025.8%20%3D%2046.5%20ohms)
![\frac{1}{R_{eq} } = \frac{1}{19.2} +\frac{1}{46.5}\\\\\frac{1}{R_{eq} } = 0.0735887097\\\\R_{eq} = 13.5890411](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Beq%7D%20%7D%20%3D%20%5Cfrac%7B1%7D%7B19.2%7D%20%2B%5Cfrac%7B1%7D%7B46.5%7D%5C%5C%5C%5C%5Cfrac%7B1%7D%7BR_%7Beq%7D%20%7D%20%3D%200.0735887097%5C%5C%5C%5CR_%7Beq%7D%20%3D%2013.5890411)
The centripetal force on the car as it goes around the second curve is twice that compared to the first.
What is Centripetal force?
It is the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.
The formula of Centripetal force is:
F(c) = (m* v^2) / r
Here,
At the first curve,
The curve of radius = r
The constant speed = v
At the second curve,
The car speed (v')= 2 v
The radius of the curve (r')=2 r
According to the formula of centripetal Force:
As the car goes around the second curve,
F'(c) = m*v'^2 / r'
F'(c) = m* (2*v)^2 / 2r
F'(c) = 2* F
Thus,
The centripetal force on the car as it goes around the second curve is twice that compared to the first.

Answer:
Friction 100 j
Explanation:
Friction causes the inequality between PE and KE
100 J
The answer is A. <span>The component waves have different frequencies.
The magnitudes of reinforcement usually really dependent on the number of frequencies and interference is usually caused due to the difference in frequencies. So, we can conclude that if the frequencies are different and causing interference, the reinforcement will also different
