A Mass Spectrometer Works by Ionizing Atoms or Molecules, and Then

question 142

Multiple Choice

A mass spectrometer works by ionizing atoms or molecules, and then accelerating them past oppositely charged plates.The mass is obtained by

• A)measuring the force of impact on a detecting screen, and then calculating the mass using force = mass \(\times\) acceleration.
• B)suspending the ions in an applied electric field, and then calculating mass by the setting the downward gravitational force equal to the upward electrostatic force.
• C)measuring the magnitude of deflection as the ions pass through a magnetic field to obtain the charge-to-mass ratio, and then calculating the mass from that ratio.
• D)measuring the time it takes for the ions to hit the detector at a known distance to calculate the acceleration, and then calculating mass from force = mass \(\times\) acceleration.

Definitions:

Muscular Tissue

A tissue composed of fibers accountable for producing force and motion in the body, including movement of organs and the body itself.

Specialized to Contract

Describes cells or tissues, such as muscle cells, that are adapted to shorten or generate force, playing a crucial role in movement and support.

Inflammation

A biological response to injury or infection, involving the mobilization of immune cells and substances to protect the body.

Blood Vessels

Tubular structures carrying blood through the tissues and organs; a part of the circulatory system.
