You'll never get the correct answer without the correct conversion factor. Note carefully that you have no decimal. It should be
<span>1 km = 0.6214 miles </span>
<span>1000 m = 1 km </span>
<span>60 seconds = 1 minute </span>
<span>60 minutes = 1 hour. </span>
<span>2.998E8 m/s x (1 km/1000m) x (0.6214 miles/km) x (60 sec/min) x (60 min/hr) = ?</span>
Explanation:
it holds protons and neutrons together
Atoms move at different speeds because of different amounts of space between each other (lots of space in a liquid so they move faster then in a solid where there is almost no space)
This is because the accerelation due to gravity on earth is 9.8m/s2 and to find the weight you multiply 12 by 9.8 which=117.6N. Therefore the force of gravity on planet A is equal to the force of gravity on Earth.
