A proton travels with a speed of 4.2×106 m/s at an angle of 30◦ west of north. A magnetic field of 2.5 T points to the north. Fi
Arada [10]

Answer:

8.4\cdot 10^{-13} N

Explanation:

The magnitude of the magnetic force on the proton is given by:

F=qvB sin \theta

where:

q=1.6\cdot 10^{-19} C is the proton charge

v=4.2\cdot 10^6 m/s is the proton velocity

B=2.5 T is the magnetic field

\theta=30^{\circ} is the angle between the direction of v and B

Substituting into the formula, we find

F=(1.6\cdot 10^{-19}C)(4.2\cdot 10^6 m/s)(2.5 T) sin 30^{\circ}=8.4\cdot 10^{-13} N

"a musical tone sounded on a piano has a frequency of 261.6 hz and a wavelength of 1.31 m. what is the speed of the sound wave
Andreyy89
To solve this question, we use the wave equation which is:
C=f*λ
where:
C is the speed;
f is the frequency;
λ is the wavelength
So in this case, plugging in our values in the problem. This will give us:
C = 261.6Hz × 1.31m
= 342.696 m/s is the answer.
