If the mass of a player triples(3x), his kinetic energy will

a) not change
b) double (2x)
c) triple(3x)
d) quadruple(4x)

c) triple(3x)

Explanation:

The equation for kinetic energy is:

if the mass triples we will have that the new kinetic energy is:

which can also be written as:

and is the original kinetic energy , so:

⇒the new kinetic energy is three times the original kinetic energy.

the answer is: his kinetic energy will triple (3x) which is option c.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
