The Lorentz force exerted on a charge moving in a magnetic field is given by:
where
q is the charge
v is the speed of the charge
B is the intensity of the magnetic field
is the angle between the directions of the field and of the velocity
The data we have in our problem are:
If we substitute these data and we rearrange the initial equation, we can calculate the speed of the particle:
so, the correct answer is
<span>1.1 × 104 m/s</span>
Answer:
Hello there!
This is a picture that helped me learn the phases in an easy way. I hope it helps you too.
Explanation:
Answer: The orbital speeds of stars far from the galactic center are surprisingly high.
Dark matter is a type of matter, whose composition is unknown and which corresponds to 80% of the matter in the universe. Its name refers to the fact it does not emit or interact with any type of electromagnetic radiation, being completely transparent throughout the electromagnetic spectrum.
<h2>However,
it interacts with the known matter through gravity. </h2><h2 />
In this sense, it is believed that the Milky Way has 90% dark matter and only 10% ordinary matter (known matter). Because, like gravity, dark matter can not be observed directly, however its existence is inferred through the movement of the stars far from the center and the cosmic dust within the galaxy.
Speaking bout mass,
it's mass is still 40Kg on the moon
but it's Weight on the moon is 1/6mg
