Answer:
138.4625 N/C
Explanation:
We have that the charge +4 nC is at the origin (0,0,0)
We have to find the electric field at point (-0.5,-0.1,0)
We know that distance between two points is given by ![d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2+(z_1-z_2)^2}=\sqrt{(0-(-0.5))^2+(0-(-0.1))^2+(0-0)^2}=0.5099m](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_1-x_2%29%5E2%2B%28y_1-y_2%29%5E2%2B%28z_1-z_2%29%5E2%7D%3D%5Csqrt%7B%280-%28-0.5%29%29%5E2%2B%280-%28-0.1%29%29%5E2%2B%280-0%29%5E2%7D%3D0.5099m)
The electric field due to a point charge is given by ![E=\frac{KQ}{R^2}=\frac{4\times 10^{-9}\times 9\times 10^{9}}{0.5099^2}=138.4625N/C](https://tex.z-dn.net/?f=E%3D%5Cfrac%7BKQ%7D%7BR%5E2%7D%3D%5Cfrac%7B4%5Ctimes%2010%5E%7B-9%7D%5Ctimes%209%5Ctimes%2010%5E%7B9%7D%7D%7B0.5099%5E2%7D%3D138.4625N%2FC)
I am not entirely sure but i believe the answer is C scupture
If you mean with the visible eye, then its radiation. we cant see radiation.
get a little more detail about the question.
Answer:
A
Explanation:
because you cannot seperate the matter duhhh hahha
Answer:
16 m / s
Explanation:
Average kinetic energy of one mole of a gas is given by the expression
K.E = 3 / 2 R T { T is absolute temperature of the gas }
Putting the values , we get
4070 = 3 / 2 X 8.312 X T
T = 326.35 K
Under similar condition temperature of oxygen will also be same . So temperature of oxygen gas will be 326.35 K.
Now ,RMS value of a gas = ![\sqrt{\frac{3RT}{M} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B3RT%7D%7BM%7D%20%7D)
T is absolute temperature of gas and M is molecular mass.
Molecular mass of oxygen is 32 gm . T is 326.35
RMS speed = ![\sqrt{\frac{3\times 8.314\times326.35 }{32} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B3%5Ctimes%208.314%5Ctimes326.35%20%7D%7B32%7D%20%7D)
= 16 m / s . approx.
