The inward and upward pulls into the diaphragm to force an obstruction out of the airway is (C) abdominal thrust.
Abdominal thrusts are needed to perform the Heimlich maneuver. That is the first aid procedure for dislodging something out of the airway of a choking person.
ANSWER: (C) abdominal thrust

Answer: a magnetic field is created by moving electric charges
The tangental acceleration of the flywheel of radius 2.12 cm with a final angular velocity of 1820 rev/min and an angular acceleration of 16.2 rad/s is 0.34 m/s².
<h3>What is tangental acceleration?</h3>
This is the rate of change of tangental velocity of an object in circular motion.
To calculate the tangental acceleration, we use the formula below.
Formula:
- a = αr............. Equation 1
Where:
- a = Tangental acceleration
- r = radius of the flywheel
- α = Angular acceleration of the flywheel.
From the question,
Given:
- r = 2.12 cm = 0.0212 m
- α = 16.2 rad/s²
Subsitute these values into equation 1
- a = (0.0212×16.2)
- a = 0.34 m/s²
Hence, The tangental acceleration of the flywheel of radius 2.12 cm with a final angular velocity of 1820 rev/min and an angular acceleration of 16.2 rad/s is 0.34 m/s².

Answer:
Mass number of carbon is 12.
Explanation:
Carbon atom is defined as 6 atoms in a nucleus, and the mass number is the total number of protons and neutrons in the nucleus of an atom.
Before any neutrons are added to the carbon atom, its mass number is 6;<em> after 6 neutrons are added, the total number of protons and neutrons is now 12—the mass number becomes 12.</em>
