The correct answer of the question given is D.

There are four body processes mentioned in the question are named as glycolysis,metabolism,photosynthesis and transduction.

Glycolysis is the metabolic process in which glucose is converted to pyruvic acid with the release of ATP and NADPH.

Metabolism is a chemical process which includes the formation or dissociation of chemical compounds.

Photosynthesis is the biological process in which food is prepared by plants by absorbing minerals, water from soil and carbon dioxide from the atmosphere in the presence of radiant energy [sun light] .

Transduction: It is the biological process in which any external physical stimuli is received and relayed from one part of the body to another part.During this process energy i.e stimuli is converted into electro chemical stimuli.

A boy of mass 80 kg slides down a vertical pole, and a frictional force of 480 N acts on him. What is his acceleration as he sli

olga_2 [115]

Answer:

His acceleration is $\overrightarrow{a}=4\frac{m}{s^{2}}$

Explanation:

Newton's second law states that acceleration of a body is cause by a net force, the relation between them is:

$\sum\overrightarrow{F}=m\overrightarrow{a}$

On the boy there're acting two forces, his weight (W) that points downward and the frictional force (f) that points upward (they boy moves downward and friction always is opposite to movement). So $\sum\overrightarrow{F}=\overrightarrow{W}+\overrightarrow{f}$ so (1) is:

$\overrightarrow{W}+\overrightarrow{f}=m\overrightarrow{a}$

Using the positive direction downward weight and gravitational acceleration(g) are positive and friction force is negative:

$W-f=m\overrightarrow{a}$ , solving for a:

$\overrightarrow{a}=\frac{W-f}{m}$ , weight is mg:

$\overrightarrow{a}=\frac{mg-f}{m}=\overrightarrow{f}=\frac{(80kg)(10\frac{m}{s^{2}})-(480)}{80}$

$\overrightarrow{a}=4\frac{m}{s^{2}}$

Because the earth revolves around the sun and the whole earth isn’t always facing the sun it changes that’s why we have night and day and summer and winter etc

Choose heated air or cooled air for the following atmospheric property term: rises

inysia [295]

I'm not really sure what you mean, but it could be heated air because 'rises' could mean temperature rising, and when temperature rises, the air heats up... i hope I'm correct and this helps you. correct me if I'm wrong.
