Complete Question
The diagram for this question is shown on the first uploaded image
Answer:
The magnitude is , the direction is into the page
Explanation:
From the question we are told that
The current is
The radius of arc bc is
The radius of arc da is
The length of segment cd and ab is =
The objective of the solution is to obtain the magnetic field
Generally magnetic due to the current flowing in the arc is mathematically represented as
Here I is the current
is the permeability of free space with a value of
r is the distance
Considering Arc da
Where is the angle the arc da makes with the center from the diagram its value is
Now substituting values into formula for magnetic field for da
Looking at the diagram to obtain the direction of the current and using right hand rule then we would obtain the the direction of magnetic field due to da is into the pages of the paper
Considering Arc bc
Substituting value
Looking at the diagram to obtain the direction of the current and using right hand rule then we would obtain the the direction of magnetic field due to bc is out of the pages of the paper
Since the line joining P to segment bc and da makes angle = 0°
Then the net magnetic field would be
Since then the direction of the net charge would be into the page
20 kg*m/s because there is 2 kg mass and 10 m/s so you can multiply.
Answer:
Pauli exclusion principle
Explanation:
No two fermions can have the same set of quantum numbers is called the Pauli exclusion principle. And a electron is a fermion.
There are four basic quantum numbers
Principle quantum number n
the angular momentum quantum number l
magnetic quantum number m_l
and electron spin quantum number m_s
Answer:
The power she can generate is 185.22 KW.
Explanation:
<h3><u>DATA</u></h3>
3.00m wide and 0.500m deep.
Cross sectional area = 1.500m^2
Velocity = 1.35m/s
Volumetric flow rate = Av = 18.00m^3/s
Mass flow rate = 18,000kg/s
Height = 4.20m
25.0% efficiency
<h3><u>
FORMULA:</u></h3>
P = dE / dt * eff
<h3><u>
SOLUTION:</u></h3>
18,000kg/s (9.8m/s^2) (4.20m) (25%) = 185,220 watts
= 185 kw
Answer:
Change in Velocity because
Explanation:
Remeber area is length times Width. In this case, the area under a accleraton vs time graph is Accleration Times Time. Which is velocity
