Answer:

D.Radiography uses ionizing radiation, but sonography does not.

Explanation:

Radiography is the process of using x-rays or gamma rays to capture images showing internal parts of the human body for medical examinations.X-rays are commonly used in this process.x-rays are categorized as a cancer causing agent thus exposure to such rays could cause development of cancer.In sonography, high frequency sound waves are used. There is no exposure to any ionization radiation like in radiography.

A force of 6.0 N is applied horizontally to a 3.0 kg crate initially at rest on a horizontal frictionless surface. After the cra

Savatey [412]

Answer:

a. Yes, because the acceleration of the crate is 2.0 m/s².

Explanation:

Given

$Force = 6N$ --- f

$Mass = 3kg$ --- m

$Time = 1.5s$ --- t

$Velocity = 3.0m/s$ --- v

Required

Does the system support $F=ma$

Yes, it does and this is shown below

The crate is initially at rest; so:

$u = 0$

Using the first equation of motion

$v = u + at$

Substitute values for v, u and t

$3 = 0 + a*1.5$

$3 = 1.5a$

Make a the subject

$a = 3/1.5$

$a = 2$

Using $F = ma$

Substitute values for F and m

$6 = 3 * a$

Divide both sides by 3

$6/3 = 3/3 * a$

$2 = a$

$a = 2$

In both cases:

$a = 2$

<em>Hence, option (a) is correct.</em>
