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

MArishka [77]

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 ( $a=1.5*10^{13} m/s^{2}$ )

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

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

$\theta=15.52^{\circ}$

A voltage amplifier with an input resistance of 40k ohms, an output resistance of 100 ohms, and a gain of 300 V/V is connected b

AfilCa [17]

Answer:

89.45 v/v

Explanation:

Let's take the data:

First draw the amplifier circuit.

After the circuit, the voltage division rule can be used to compute the parameters:

The input section is computed like this: $\frac{R_{in} }{(R_{sig} + R_{in} } (v_{sig})$

The output section is computed like this $R_{L}/ (R_out} + R_{in} )$

The product A $V_{in} V_{out}$ gives

A $V_{in} V_{out}$ = A× $\frac{R_{in} }{(R_{sig} + R_{in} } (v_{sig})$ × $R_{L}/ (R_out} + R_{in} )$

Computing gives output voltage = 89.45 v/v

27 degrees to kelvin, 20 dg to milligrams, and 3 to decimeters.

Gala2k [10]

K = C + 273, so 27°C = 27+273 = 300 K

1 dg = 100 mg, so 20 dg = 20×100 = 2,000 mg
