Answer:
F=1.4384×10⁻¹⁹N
Explanation:
Given Data
Charge q= -8.00×10⁻¹⁷C
Distance r=2.00 cm=0.02 m
To find
Electrostatic force
Solution
The electrostatic force between between them can be calculated from Coulombs law as
![F=\frac{kq^{2} }{r^{2} }](https://tex.z-dn.net/?f=F%3D%5Cfrac%7Bkq%5E%7B2%7D%20%7D%7Br%5E%7B2%7D%20%7D)
Substitute the given values we get
![F=\frac{(8.99*10^{9} )*(-8.00*10^{-17} )^{2} }{(0.02)^{2} }\\ F=1.4384*10^{-19} N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B%288.99%2A10%5E%7B9%7D%20%29%2A%28-8.00%2A10%5E%7B-17%7D%20%29%5E%7B2%7D%20%7D%7B%280.02%29%5E%7B2%7D%20%7D%5C%5C%20F%3D1.4384%2A10%5E%7B-19%7D%20N)
Answer:
the impedance of the circuit is 25.7 ohms.
Explanation:
It is given that,
Voltage, V = 50 volts
Frequency, f = 60 Hz
Resistance, R = 25 ohms
Capacitive resistance, ![X_C=18\ ohms](https://tex.z-dn.net/?f=X_C%3D18%5C%20ohms)
Inductive resistance, ![X_L=24\ ohms](https://tex.z-dn.net/?f=X_L%3D24%5C%20ohms)
We need to find the impedance of the circuit. It is given by :
![Z=\sqrt{R^2+(X_L-X_C)^2}](https://tex.z-dn.net/?f=Z%3D%5Csqrt%7BR%5E2%2B%28X_L-X_C%29%5E2%7D)
![Z=\sqrt{25^2+(24-18)^2}](https://tex.z-dn.net/?f=Z%3D%5Csqrt%7B25%5E2%2B%2824-18%29%5E2%7D)
Z = 25.7 ohms
So, the impedance of the circuit is 25.7 ohms. Hence, this is the required solution.

Answer:
It is the carrier of genetic information.
' C ' is the only correct statement on the list. We don't know anything about diagram-x or diagram-y because we can't see them.
