<em>v</em>² - <em>u</em>² = 2 <em>a</em> ∆<em>x</em>
where <em>u</em> = initial velocity (27 m/s), <em>v</em> = final velocity (0), <em>a</em> = acceleration (-8 m/s², taken to be negative because we take direction of movement to be positive), and ∆<em>x</em> = stopping distance.
So
0² - (27 m/s)² = 2 (-8 m/s²) ∆<em>x</em>
∆<em>x</em> = (27 m/s)² / (16 m/s²)
∆<em>x</em> ≈ 45.6 m
Heat pumps are also known as refrigeration units for heating and cooling homes by taking heat from air outside in the winter time and then reversed to take heat out of the inside of a home in the summertime. The Geothermal heat pumps take heat from the ground by way of buried pipes deep in ground with chemicals such as water and glycol or similar and transfers that heat into homes in the winter time.

Everything in the universe that is not a star reflects light from Stars. Otherwise you can't see it.
Answer:
9
Explanation:
A atomic number is the addition of every number
Answer: 0.192 N/m
Explanation:
Well, generally when a Hooke's Law experiment is performed the plot is in fact Force vs Displacement, being the Force (in units of Newtons) in the Y-axis and the Displacement (in units of meters) in the X-axis.
In addition, if we add a linear fit the resultant equation will be the Line equation of the form:
Where 
is the slope and 
is the point where the line intersects the Y-axis.
So, if the equation is:
The slope of this line is 
which is also the spring constant 
.
