If the number of crests that pass a point in a given time increases, what has increased?
zysi [14]
The frequency increasing makes the crests pass more quickly.  Frequency is a count of how many times per second an event occurs.  In waves, this event is the passing of an entire cycle.  Once the cycle has passed, the wave repeats.  The faster the wave repeats, the higher the frequency.  For this reason, frequency has units of hertz, Hz.  The unit of hertz is 1/s or "per second"

A proton is projected perpendicularly into a magnetic field that has a magnitude of 0.50 T. The field is then adjusted so that a
bixtya [17]

Answer:

B_e = 2.72 \times 10^{-4} T

Explanation:

As we know that when charge particle is projected in perpendicular magnetic field then the radius of the charge particle is given as

F = qvB

\frac{mv^2}{r} = qvB

now we have

r = \frac{mv}{qB}

since here radius of proton and electron will be same

so we will have

r_e = r_p

\frac{m_e v}{q_e B_e} = \frac{m_p v}{q_p B_p}

so we have

B_e = \frac{B_p m_e}{m_p}

given that

B_p = 0.50 T

m_e = 9.11 \times 10^{-31} kg

m_p = 1.67 \times 10^{-27} kg

so we have

B_e = \frac{0.50(9.11\times 10^{-31})}{1.67\times 10^{-27}}

B_e = 2.72 \times 10^{-4} T
