One
A wire carrying a current creates a circular field. Not A.
B is pretty uniform. I would pick it.
C The lines bend around the north and south poles. Not C
D Same Remark as C.
Two
- The force exerted by the magnetic field is the palm of your right hand.
- Your thumb is the direction of the charged stream
- The fingers are the direction of B which I take to be into the page.
If all these are in agreement with what you think you have been given then A is the correct answer. The proton will be defected in the direction of the palm.
Three
As stated in One the fingers point in the direction of B, The thumb is the direction of the charge and the palm is the direction of the force when the item is a plus charge. When the travelling charge is minus as this one is, use the back of your hand. In that case, The electron will be deflected downward. This assumes the Magnetic field is pointing into the page.
The answer is A.
When using the spectroscope to view the spectra of the discharge lamps, what observations are recorded by the wavelengths and colors of all bands.
<h3>Spectra of discharge lamps</h3>
The spectra of discharge lamp from spectroscope shows the different electromagnetic spectrum, they include the following;
- Ultraviolet rays
- Visible lights
- Infra-red, etc
The electromagnetic spectrum consists of radiations of different wavelengths which are indicated by different color bands.
Thus, when using the spectroscope to view the spectra of the discharge lamps, what observations are recorded by the wavelengths and colors of all bands.

The radius of its orbit, measured from Earth's center, will be 1.44 × 10⁷ mm.
<h3>What is Newton's law of gravitation?</h3>
Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.
Given data in problem is;
The mass of Earth is, 
Gravitational constant, G =6.674 × 10⁻¹¹ N m₂/kg²
The gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.
The centripetal force due to rotation of the satellite;
The centripetal and the gravitational force are equal;
