The answer is D jessim should spin the glove quickly while walking in a circle around nancy.
Answer:
The correct answer is D Air molecules touch the warm ground, heating them up.
Explanation:
There are three types of thermal energy: Conduction, convection, and radiation. Conduction is the process in which energy (also known as heat) is transferred from one object to another by directly touching each other (solids touching solids). Convection is the process in which energy is circulated through the movement of fluids (like liquids or gases), by hot air rising and cool air sinking. Radiation is the process in which energy is transferred from one place to another by electromagnetic waves. An example of this would be feeling warm after being outside in the sun; such as choice B, which is hence incorrect. Choice A is a rephrasing of choice C; both of which are considered convection because air is not a solid, but a gas and this air is <em>rising </em>and<em> sinking</em>. This leaves us with choice D. Choice D would be considered conduction because the air molecules are <em>touching</em> the ground; therefore, being heated <em>directly</em>.

Answer: the person standing up
Explanation:
the person has the potential to fall or move from position
Answer:
D) atomic radii increase from top to bottom of a group
Explanation:
Atomic radii trend along group:
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
As the size of atom increases the ionization energy from top to bottom also decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.
Other options are incorrect because,
A) atomic radii increase from left to right across the period
Correct = atomic radii decreases from left to right across the period
B) ionization energy increases from top to bottom within a family
Correct = ionization energy decreases from top to bottom within a family
C) electronegativity decreases from left to right across a period
Correct = electronegativity increases from left to right across a period
