Answer:
Approximately (approximately ) assuming that the magnetic field and the wire are both horizontal.
Explanation:
Let denote the angle between the wire and the magnetic field.
Let denote the magnitude of the magnetic field.
Let denote the length of the wire.
Let denote the current in this wire.
The magnetic force on the wire would be:
.
Because of the term, the magnetic force on the wire is maximized when the wire is perpendicular to the magnetic field (such that the angle between them is .)
In this question:
- (or, equivalently, radians, if the calculator is in radian mode.)
- .
- .
- .
Rearrange the equation to find an expression for , the current in this wire.
.
Answer:
the shape how it involve into a picture
Explanation:
Answer:
Explanation:
The energy of a photon is: when h is the Planck constant.
Then, we calculate the energy of a photon with a wavelength equal to 550 nm.
To find the number of photons we can use this equation:
Have a nice day!
U can try to use capacitor , the value of capacitor depends on circuit
ripple factors signifies the ac components, by def its ratio of rms value of ac component to value of dc component
so in order to reduce use of a capacitor which denies the sudden changes in voltage, which is the charracteristic of Ac signals
hope this helps
