Answer:
a) Ф = 0.016 N / C m
, b) q_{int} = 0.14 10⁻¹² C
Explanation:
a) For this problem we use Gauss's law
Ф = E .ds = /ε₀
The camp is in the x direction so it has no flow through the cylinder walls.
Ф = E A
The area of a circle is
A = π r
Ф = E π r
Ф = (x- 3.6) r
Let's calculate
Ф = (3.7 -3.6) 0.16
Ф = 0.016 N / C m
b) we clear from Gauss's law
q_{int} = Ф ε₀
Where the flow is on both sides, on the face at x = 0 the flow is zero
q_{int} = 0.016 8.85 10⁻¹²
q_{int} = 0.14 10⁻¹² C
Answer:
Explanation:
There is no set way to do this. All you have to do is define left and right. Left will be minus and right will be the opposite --- plus.
That is completely arbitrary. It could be the other way around. It does not matter.
Left is minus so: - 600 N is the force going left.
Right plus so: + 500 N
Now just add.
Net Force = +500 - 600
Net Force = - 100 N
So the Net Force is - 100 N going to the left.

Explanation:
Given data
At d₁=4.5×10¹⁰m the speed of comet is Vi=9.2×10⁴m/s
At d₂=6×10¹²m the speed will Vf
The work done by surrounding is zero and the energy of system at the initial state equal the energy at final state so we can apply:
Substitute the given values to find final velocity Vf
So
Explanation:
Every valid chemical equation must be balanced i.e the same number of atoms must be present on both sides of the equation.
The law of conservation of mass states that "matter cannot be created nor destroyed in a chemical reaction but are transformed from one form to another".
- A chemical equation contains reactants on the left hand side.
- On the right hand side, the products are formed.
- For the reaction to be valid, there must be equal numbers of atoms of any specie on both sides of the equation.
- This way the law of conservation of mass holds true.
