Gravity is a non contact force , jump from a little high place (don't do that :P) , you wont just get stuck in the air you will fall down , this is gravity you dont need any contact
Answer: 166.67km/hr
Explanation:
Given the following :
Distance traveled = 250km
Time taken = 1.5 hours
Recall :
Speed = Distance traveled / time taken
Speed = 250 km / 1.5 hours
Speed = 166. 67 km/hr
Speed in m/s:
166.67km/hr = (166.67 × 1000)m / 3600 s
= 166670m / 3600s
= 46.3m/s
Laurentia, also called the North American Craton, is a huge continental craton.

1) G. The continents are now farther apart.
2) A. P waves. They usually travel 60% faster than S waves.
3) H. A hot spot caused the Hawaiian Islands to form.
This is because, different colored object absorbs differnt wavelenght of light making it appears with different color. There is a spectrum of white light in which red have the longest wavelength.
Hope this will help.
