A cyclotron designed to accelerate protons has a magnetic field of magnitude 0.15 T over a region of radius 7.4 m. The charge on
klio [65]

Explanation:

It is given that,

Magnetic field, B = 0.15 T

Charge on a proton, q=1.60218\times 10^{-19}\ C

Mass of a proton, m=1.67262 \times 10^{-27}\ kg

The cyclotron frequency is given by :

f=\dfrac{qB}{2\pi m}

f=\dfrac{1.60218\times 10^{-19}\ C\times 0.15\ T}{2\pi \times 1.67262 \times 10^{-27}\ kg}

f = 2286785.40 Hz

or

\omega=14368296.44\ rad/s

\omega=1.43\times 10^7 rad/s

Hence, this is the required solution.

A 2kg bowling ball rolls at a speed of 5 m/s on a roof of the building that is 40 meters tall. What is the kinetic energy
MrRa [10]
The kinetic energy is \frac 1 2 m v^2 and the height of the building doesn't matter at all.

E = \frac 1 2 m v^2 = \frac 1 2 (2)(5)^2 = 25 joules

In AA&amp;E storage facilities, why must drainage structures be secured if they cross the fence line and meet certain size requi
Likurg_2 [28]

Answer:

As an additional security measure in an AA&E storage facilities, securing drainage structures  must be considered if their cross section is greater than 96 inches  and any dimension is greater  than 6 inches, they must be  barred and welded at the  intersections to prevent any  human from crawling into the  area.

Explanation:

U.S. national security relys on ensuring DoD sensitive or classified assets such as classified material, arms, ammunition, and explosives  (AA&E) and nuclear weapons, in properly safeguard facilites and storage containers, voiding DoD assets loss or  compromise and additional to supplemental intrusion detection systems and guard patrols, security lighting, communications, fences and clear zones, drainage structures, key control, and other security measures required to protect  AA&E.
