An electron is moving through a magnetic field whose magnitude is 9.21 × 10^-4 T. The electron experiences only a magnetic force
Marysya12 [62]

Answer:

\theta=10.60^{\circ}

Explanation:

Given that,

Magnetic field, B=9.21\times 10^{-4}\ T

Acceleration of the electron, a=2.3\times 10^{14}\ m/s^2

Speed of electron, v=7.69\times 10^{6}\ m/s

The force due to this acceleration is balanced by the magnetic force as :

ma=qvB\ sin\theta

sin\theta=\dfrac{ma}{qvB}

sin\theta=\dfrac{9.1\times 10^{-31}\times 2.3\times 10^{14}}{1.6\times 10^{-19}\times 7.69\times 10^{6}\times 9.21\times 10^{-4}}

\theta=10.60^{\circ}

So, the angle between the electron's velocity and the magnetic field is 10.6 degrees. Hence, this is the required solution,

I need to know the correct answer please ?
mrs_skeptik [129]

Answer:

675 Pa.

Explanation:

F = 5+2cos(15t) kN

Area (a) = 8*10-3 m2

Now at t =4 sec

            F= 5+2cos(60)

             = 5+2*0.5

              = 6  kN

Now ,force efficiency is 90%.

Hence,the effectively transmitted force,

            Fe = 0.90*6

                = 5.4 kN

Hence,pressure is given as,

            P = Fe/a

                = 5.4*10^3/(8 *10^-3))

              P = 675 Pa....answer

A Semi truck(m=20,000kg) is 10 m from a car(m=200kg). What is the force of gravity between them(G=6.67*10^-11N•m^2/kg^2)
gregori [183]

Answer:

F = 2.668*10_-6[N]

Explanation:

We can calculate this force using the law of universal gravitation raised by Isaac Newton

m_{t}=20000[kg]\\m_{c}= 200[kg]\\r = 10[m]\\G = 6.67*10^{-11}[\frac{N*m^{2} }{kg} ] \\

And the force is given by the following expression:

F=G*\frac{m_{t}*m_{c}}{r^{2} } \\F=6.67*10^{-11} *\frac{20000*200}{10^{2} }\\F=2.668*10^{-6} [N]
