An 0.075 c point charge's surrounding gaussian surface's electric flux is 8.5 ×10⁹Nm²/C.
<h3>Which is a gaussian surface?</h3>In three dimensions, the Gaussian surface is referred to as a closed surface where the flux of a vector field may be determined. The gravitational field, the electric field, or the magnetic field are all examples of these vector fields.
<h3>Why is a Gaussian surface drawn?</h3>We build a fictitious Gaussian surface around the supplied surface when the surface of which an electric field or flux must be established is asymmetrical or the surface area is challenging to obtain, such as the surface area for an infinitely long wire or plane. The Gaussian surface is said to utilize symmetry the best.
When a charge q is surrounded by a gaussian surface, the electric flux that passes through it is
= 0.075 / ( 8.85 ×10⁻¹²)
= 8.5 ×10⁹Nm²/C.

Answer:
the period of the 16 m pendulum is twice the period of the 4 m pendulum
Explanation:
Recall that the period (T) of a pendulum of length (L) is defined as:
where "g" is the local acceleration of gravity.
SInce both pendulums are at the same place, "g" is the same for both, and when we compare the two periods, we get:
therefore the period of the 16 m pendulum is twice the period of the 4 m pendulum.
Answer:
4.4 cm
Explanation:
Given:
Distance of the screen from the slit, D = 1 m
Distance between two third order interference minimas, x = 22 cm
Let's say, minima occurs at:
We have:
Calculating further for the width of the central bright fringe, we have:
= 4.4 cm
Note: w in representswavelength
Answer:
0.25 L
Explanation:
= Initial pressure = 1 atm
= Initial Temperature = 20 °C
= Initial volume = 4.91 L
= Final pressure = 5.2 atm
= Final Temperature = -196 °C
= Final volume
From ideal gas law we have
The pressure experienced by the balloon is 0.25 L
