The answer is B. rotational motion
If you've ever mixed water and oil together,you've probably noticed that the oil rises to the top and the water stays at the bottom-- no matter how much you try to shake them. This is because oil is less dense than water, making it float to the top. The molecules in oil are larger than those in water, so they don't pack as tightly together as they do in water. In a mixture of oil and vinegar, the<span> </span>oil <span>floats on the </span>vinegar/<span>water mixture, while the solids sink to the bottom. So, if one material floats over another, the material on top is less dense.

Answer:
F = 2985.125 N
Explanation:
Given that,
The radius of curvature of the roller coaster, r = 8 m
Speed of Micheal, v = 17 m/s
Mass of body, m = 65 kg We need to find the net force acting on Micheal. Net force act the bottom of the circle is given by :
So, the net force is 2985.125 N.
Answer:
1.3889 x 10¹¹ miles.
Explanation:
2 Years = 2 x 365 days = 730 days
2 years and 9 days = 739 days .
739 days = 739 x 24 = 17736 hours
2 years 9 days and 4.5 hours = 17736 + 4.5 = 17740.5 hours
17740.5 hours = 17740.5 x 60 x 60 = 63.865 x 10⁶ s
Distance travelled = velocity x time
2174.799173 x 63.865 x 10⁶ = 1.3889 x 10¹¹ miles.
