Answer:
Explanation:
a )
The Gaussian surface must have contained both the charges like +3 nC and - 3 nC , total charges being zero . According the Gauss's law , total electric flux over a closed surface is equal to 1 / ε₀ times the total charge contained inside the closed surface .
Since total charge inside is zero , total flux will be 1 / ε₀ x 0 = 0
b )
In this case the Gaussian surface is so small that it contains only the charge
+ 3 nC .
So electric flux over the Gaussian surface
= ( 1 / ε₀ ) x 3 x 10⁻⁹
= (1 / 8.85 x 10⁻¹² ) x 3 x 10⁻⁹
= 3 x 10³ / 8.85
= 339 weber.
=
Answer: 2.85 N.s
Explanation: Impulse is the product of force and time or expressed in the following formula:
J = F x t
= 475 N x 0.006 s
= 2.85 N.s
Answer:
energy cannot be created or destroyed
Explanation:
Energy can't be created nor destroyed; rather, it transforms from one form to another.
Okay, I am going to use solar prominence and solar flares.
So, Solar Prominence is a large, bright, gaseous feature extending outward from
the Sun's surface, often in a loop shape. Prominence are anchored to
the Sun's surface in the photo-sphere, and extend outwards into the Sun's
corona.
A solar flare is a sudden flash of brightness observed near the Sun's
surface. It involves a very broad spectrum of emissions, requiring an
energy release of up to 6 × 10²⁵ joules of energy (roughly the
equivalent of 160,000,000,000 megatons of TNT, over 25,000 times more
energy than released from the impact of Comet Shoemaker–Levy 9 with
Jupiter).
Hope this helps
