What is the potential energy of a pendulum with a mass of 0.7 kg, a height of 0.3 m, and a value of g equal to 9.8 m/s 2 ?

2.1J

Explanation:

Given parameters:

Mass of pendulum  = 0.7kg

Height of pendulum = 0.3m

Acceleration due to gravity  = 9.8m/s²

Unknown:

Potential energy of the pendulum  = ?

Solution:

The potential energy of a body is the energy due to the position of that body;

 Potential energy  = mass x acceleration due to gravity x height

Insert the parameters and solve;

Potential energy  =0.7kg x 0.3m x 9.8m/s²  

 Potential energy  = 2.1J

they may bind directly to special “promoter” regions of dna, which lie upstream of the coding region in a gene, or directly to the rna polymerase molecule.

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.
