The answer is: A; Free Energy
The force of gravity is the force with which massively large objects such as the earth attracts another object towards itself. All objects of the earth exert a gravity that is directed towards the center of the earth. Therefore, the force of gravity of the earth is equal to the mass of the object times acceleration due to gravity.

<span>4.9N = m (9.8 m/s^2), note that N (newtons) = kg-m/s^2 </span>
m = 0.5 kg
<span>The mass of the object is 0.5kg.</span>
Answer: Aluminum, because it allows heat to flow easily.

Answer:1.59
Explanation: For every mol of Ca(OH)2 there are two moles of OH so the concentration of OH is .013 x2 =.026 M OH
pOH = - log [OH] so -log .026 = 1.59
Answer:
Charlotte traveled 319.50 feet during this time.
Explanation:
Speed of the Charlotte's car = 56.0 miles/hour
1 hour = 3600 seconds
Then 56.0 miles/h :
Duration of time for which she took off her eyes from the road : 3.89 s
Distance covered in 3.789 seconds:
1 mile = 5280 ft
Charlotte traveled 319.50 feet during this time.
