The answer to the question above is "630.25 hours" which is the time to recoup the difference in the water heater cost. This problem can be solved using a simple algebra equation which stated as (18*115*0.1/1000)x - (4*220*0.1/1000)x = $75. In this formula, x represents the time to recoup the difference in the water heater cost (Calculation: 0.207x-0.088x=75 --> 0.119x = 75 --> x = 630.25)<span>. </span>
Many marine species, including coral, need calcium carbonate to build their protective shells and exoskeletons. Without it, shells grow slowly and become weak. Therefore, ocean acidification impacts Coral reefs with breakable, slow-growing corals erode more quickly than they accrete.
Answer:
Explanation:
Given
Person on earth can jump to a height
initial velocity is u
using
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
final velocity is zero
On moon surface acceleration due to gravity is \frac{1}{6}[/tex] th of earth gravity
so height attained is given by
divide 1 and 2 we get
To develop this problem we will proceed to convert all units previously given to the international system for which we have to:
PART A ) From the given values the minimum acceleration will be given for 120Lb and maximum acceleration when 170Lb is reached therefore:
Through the Newtonian relationship of the Force we have to:
PART B) For the maximum magnitude of the acceleration downward we have that:
Through the Newtonian relationship of the Force we have to:
