Which of the following statements about the force on a charged particle due to a magnetic field are not valid?

1 answer:

5 0

The correct answer is "None of the above; all of these statements are valid." All the statements namely, it depends on the particle's charge, it depends on the strength of the external magnetic field, it depends on the particle's velocity, and it acts at right angles to the direction of the particle's motion are all valid. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.

How does the temperature of water affect the speed of the sound waves?

nikitadnepr [17]

Answer:

Temperature is also a condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.

Sirius and its companion orbit around a common center of mass with a period of 50 years. The mass of Sirius is 2.35 times the ma

s2008m [1.1K]

Answer:

1 solar masses

Explanation:

-Sirius has to maintain equilibrium with it's companion.

-Let x be the mass of Sirius and y be the mass of it's companion.

-From the question, we know that Sirius is 2.35 times heavier than it's companion:

$\frac{x}{y}=2.35\\\\\frac{x}{y}=\frac{2.35}{1}$
