Answer:
- magnitude : 1635.43 m
- Angle: 130°28'20'' north of east
Explanation:
First, we will find the Cartesian Representation of the and
vectors. We can do this, using the formula
where its the magnitude of the vector and θ the angle. For
we have:
where the unit vector points east, and
points north. Now, the
will be:
Now, taking the sum:
This is
Now, for the magnitude, we just have to take its length:
For its angle, as the vector lays in the second quadrant, we can use:
Answer:
Area of the plates of a capacitor, A = 0.208 m²
Explanation:
It is given that,
Charge on the parallel plate capacitor,
Electric field, E = 3.1 kV/mm = 3100000 V/m
The electric field of a parallel plates capacitor is given by :
A = 0.208 m²
So, the area of the plates of a capacitor is 0.208 m². Hence, this is the required solution.
Answer:
The wavelength is
Explanation:
From the question we are told that
The wavelength of the red laser is
The spacing between the fringe is
The spacing between the fringe for smaller laser point is
Generally the spacing between the fringe is mathematically represented as
Here is the distance to the screen
and d is the distance of the slit separation
Now for both laser red light light and small laser point D and d are same for this experiment
So
=>
Where is the wavelength produced by the small laser pointer
So
=>
