A 5.6 MeV (kinetic energy) proton enters a 0.39 T field, in a plane perpendicular to the field. What is the radius of its path?

Kisachek [45]

Answer:

the radius of the protons path is r = 0.85 m.

Explanation:

the force due to magnetic fields lead to the cetripetal force, such that:

F = q×v×B = m×(v^2)/r

q×B = m×v/r

then:

r = m×v/q×B

r = p/q×B

then, the kinetic energy of the proton:

K = 1/2×m×v^2 = p^2/(2×m)

q×B = \sqrt{2×m×K}/r

r = \sqrt{2×m×K}/(q×B)

= \sqrt{2×(1.67×10^-27)×(5.3×1.60×10^-13)}/(1.60×10^-19×0.39)

= 0.85 m

dayshawn is traveling at 12 m/s away from the school. dayshaun's mom is looking for him because he is late coming home so she le

vivado [14]

Speed of Dayshawn travelling towards his home is 12 m/s

Speed of her mom towards his school is 5 m/s

They both starts at same time so whenever they will meet on their path the sum of the distance covered by Dayshawn and distance covered by his mom must be equal to the total distance of school and home

Now let say they both meet after "t" time when they starts motion

so we can write the total distance between school and home as

$d = v_1*t + v_2*t$

here d = 6492 m

$v_1 = 12 m/s$ = speed of dayshawn

$v_2 = 5 m/s$ = speed of his mom

now by solving the above equation

$6492 = 12t + 5 t$

$t = \frac{6492}{17}$

$t = 381.9 s$

so they will meet after 381.9 s from start which will be 3.36 minutes from there start

Also at this time the distance covered by her mom will be

$d_2 = v_2*t$

$d_2 = 5* 381.9 = 1909.4 m$

so they will meet at distance 1909.4 m from their home

How is light generated?

Fudgin [204]

<span>electrons change momentum, some of them slough off photons. And some of those photons have energy in the visible light range of the electro-magnetic spectrum. </span>
