Answer:
E=Ur/2E_{0}
Explanation:
Consider a long cylindrical charge distribution of radius R with a uniform charge density rho. (a) Find the electric field at distance r from the axis where r R.
to find the electric point inside the cylinder
r=radius of the cylinder
A=curved surface area of the cylinder
∪=charge density
Q=is the net charge
V=volume of the cylinder
Q=UV
volume of the gaussian cylinder =
Q=U
area A=
Write the expression Gaussian law
∅=∫EdA=Q/..........................1
E_{0} is the permittivity of free space and Eois the electric field
rewriting the equation 1 , we have
EA=Q/E_{0}
substituting for A and also for Volume V in the equation above
E*=U/E_{0}
E=Ur/2E_{0}
To reach a vertical height of 13.8 ft against gravity, which has an acceleration of 32 ft/s^2, the required vertical speed can be calculated from the equation:
vi^2 - vf^2 = 2*g*h
Given that it has vf = 0 (it is not moving vertically at its maximum height), g = 32, and h = 13.8, we can solve for vi:
vi^2 = 29.72 ft/s
This is only its vertical speed, so this is equivalent to its original speed multiplied by the sine of the angle:
29.72 ft/s = (v_original)*(sin 42.2<span>°</span>)
v_original = 44.24 ft/s
Converting to m/s, this can be divided by 3.28 to get 13.49 m/s.
Answer:
water temperatures and global wind is correct dont listen to the other one i got it incorrect because of them
Explanation:
Answer:
B. It has increased the chili's potential energy
Explanation:
When there is an increase in the kinetic energy of a substance, the vibrations of atoms and molecules of the substance increases.
This kinetic energy increases the thermal energy of the substance.
So, when there is a decrease in the thermal energy of a substance, the kinetic energy decreases because the random motion of the molecules or atoms becomes feeble.
If the kinetic energy of the substance decreases, the potential energy of the substance increases.
So, if the chili has cooled after 10 minutes, it has increased the potential energy of the substance.
