A proton travels through a region of uniform magnetic field at an angle \thetaθ relative to the magnetic field. The magnitude of

the magnetic field in this region is 1.17 T, and the proton's velocity is 500,000 m/s when it experiences an acceleration whose magnitude is 1.50 \times 10^{13}~\frac{m}{s^2}1.50×10 ​13 ​​ ​s ​2 ​​ ​ ​m ​​ . Calculate the angle \thetaθ

Answer:

\theta=15.52^{\circ}

Explanation:

The magnitude of the force of a moving cahrge, in our case a proton, trought a magentic field is given by:

F=|q||vB|sin(\theta) (1)

where:

q is the proton charge (q=1.6*10^{-19} C)

v is the proton velocity (v=5*10^{5} m/s)

B is the magnetic field (B = 1.17 T)

Now, we just need to solve the equaton (1) for \theta.

\theta=sin^{-1}\left(\frac{F}{qvB}\right)

But the force F = ma, then:

m is the mass of proton  (m=1.67*10^{-27} kg)

a is the acceleration (a=1.5*10^{13} m/s^{2})

\theta=sin^{-1}\left(\frac{m_{p}a}{q_{p}vB}\right)

\theta=sin^{-1}\left(\frac{1.67*10^{-27}*1.5*10^{13}}{1.6*10^{-19}*5*10^{5}*1.17}\right)

\theta=15.52^{\circ}

I hope it helps you!

What is the density of a cube that has a mass of 3.75 g and a volume of 3 mL?
valina [46]

Answer:

\displaystyle \rho=1.25\ g/ml

Explanation:

<u>Density </u>

The density of a substance is the mass per unit volume. The density varies with temperature and pressure.

The formula to calculate the density of a substance of mass (m) and volume (V) is:

\displaystyle \rho=\frac{m}{V}

The cube has a mass of m=3.75 g and a volume of V=3 ml, thus the density is:

\displaystyle \rho=\frac{3.75\ g}{3\ ml}

\boxed{\displaystyle \rho=1.25\ g/ml}

Since 1 kg=1000 mg and 1 lt = 1000 ml, the density has the same value but with different units:

\displaystyle \rho=1.25\ kg/l
