Here’s some blog entrie ideas i got: Nuclear materials came into existence in the 1950s and began to grow as an internationally recognized field of endeavor late in that decade. Nuclear material refers to the metals uranium, plutonium, and thorium, in any form, according to the IAEA..... use that as a starter then i would list what a couple of them do, what environments they’re safe in, how they can be harmful etc. i’m gonna go look for some more stuff for the next entrie hold on, or u could message me and i’ll give you more info

A mechanic uses a jack to lift up a car. He exerts a force of 11,000 N at a distance of 3m from the axis of rotation. How much t

pshichka [43]

Answer:

<h2>The amount of torque put on the car is 33,000Nm</h2>

Explanation:

Formula for calculating torque is expressed as T = rFsin $\theta\\$ where;

r is the radius of the of the arm of the jack = 3m

F is the force exerted = 11000

$\theta\\$ is the angle of rotation = 90°

On substituting;

$T = 3*11000sin90^{o} \\T = 3*11000 (sin90^{o} =1)\\T = 33000Nm$

What are the three most important types of units in radiobiology? Explain the meaning of each.

Rom4ik [11]

Answer:

Most adverse health effects of radiation exposure may be grouped in two general categories:

deterministic effects (harmful tissue reactions) due in large part to the killing/ malfunction of cells following high doses; and

stochastic effects, i.e., cancer and heritable effects involving either cancer development in exposed individuals owing to mutation of somatic cells or heritable disease in their offspring owing to mutation of reproductive (germ)

If the frequency of a wave is 400hz and it’s wave length is2.5 what is the velocity ?

gizmo_the_mogwai [7]

To begin with, we can use the formula that links frequency, wavelength and velocity.

Because you already have the wavelength and the frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.

Therefore, 400 x 2.5 = 1000m/s.

Hope this helps :)

Calculate the acceleration of a helium nucleus (charge +2e, where e-electronic charge), when it enters an electric field of stre

konstantin123 [22]

Answer:

3.8 x 10^10 m/s^2

Explanation:

Charge, q = 2 e = 2 x 1.6 x 10^-19 C = 3.2 x 10^-19 C

Electric field strength, E = 790 N/C

mass of helium nucleus, m = 6.645 x 10^-27 Kg

the force due to electric filed on a charge particle is given by

F = q x E

Where, q be the charge on the charged particle and E be the strength of electric field.

By substituting the values

F = 3.2 x 10^-19 x 790

F = 2528 x 10^-19 N

According to the Newton's second law

F = m x a

Where, me be the mass and a be the acceleration

By substituting the values

$2528\times 10^{-19}=6.645\times 10^{-27}\times a$

a = 3.8 x 10^10 m/s^2
