The lowest energy waves in the electromagnetic spectrum

are the ones we call "radio waves". (But infrared waves have

pretty low energy too.)


The highest energy waves in the electromagnetic spectrum

are the ones we call "gamma rays". (But X-rays have pretty

high energy too.)

A cosmic ray proton moving toward the Earth at 3.5x 10^7 ms experiences a magnetic force of 1.65x 10^-16 N. What is the strength
Step2247 [10]

Answer:

Magnetic field, B=4.16\times 10^{-5}\ T

Explanation:

It is given that,

Velocity of proton, v=3.5\times 10^7\ m/s

Magnetic force, F=1.65\times 10^{-16}\ N

Charge of proton, q=1.6\times 10^{-19}\ C

We need to find the strength of the magnetic field if there is a 45° angle between it and the proton's velocity. The formula for magnetic force is given by :

F=qvB\ sin\theta

B=\dfrac{F}{qv\ sin\theta}

B=\dfrac{1.65\times 10^{-16}}{1.6\times 10^{-19}\times 3.5\times 10^7\times sin(45)}

B = 0.0000416 T

B=4.16\times 10^{-5}\ T

Hence, this is the required solution.

Nonamiya [84]
The equation for calculating the Work is very simple that is Work=Force x Displacement. We have a Force given as 209N and displacement = 10 meter.
Putting these values directly in the formula gives us Work = 209N x 10m
Work = 2090 Joule.

The weight of the bricks is not needed hear.

Tcecarenko [31]

To solve this problem it is necessary to resort to the energy conservation equations, both kinetic and electrical.

By Coulomb's law, electrical energy is defined as

EE = \frac{kq_1q_2}{d}

Where,

EE = Electrostatic potential energy

q= charge

d = distance between the charged particles

k = Coulomb's law constant

While kinetic energy is defined as

KE = \frac{1}{2} mv^2

Where,

m= mass

v = velocity

There by conservation of energy we have that

EE= KE

There is not Initial kinetic energy, then

\frac{kq_1q_2}{d}-\frac{kq_1q_2}{d'} = 2*\frac{1}{2}mv_f^2

\frac{kq_1q_2}{d}-\frac{kq_1q_2}{d'} = mv_f^2

v_f^2= \frac{\frac{kq_1q_2}{d}-\frac{kq_1q_2}{d'} }{m}

v_f = \sqrt{\frac{\frac{kq_1q_2}{d}-\frac{kq_1q_2}{d'}}{m}}

Replacing with our values we have,

v_f = \sqrt{\frac{\frac{(9*10^9)(12*10^{-6})(60*10^{-6})}{1}-\frac{(9*10^9)(12*10^{-6})(60*10^{-6})}{3}}{5.50*10^{-15}}}

v_f = 2.802*10^7m/s

Therefore the speed of particle B at the instat when the particles are 3m apart is 2.802*10^7m/s
