Brendan drew a diagram to illustrate the centripetal force acting on a satellite.
How can Brendan correct his diagram?
Draw the Fg = Fc vector so it points at a 45° angle from the v vector.
Change the Fg = Fc vector label so it reads Fa = Fc.
Draw the Fg = Fc vector so it is longer than the v vector.
Change the Fg = Fc vector so it is perpendicular to the v vector.
D is the answer
Explanation:
Extrusive rocks may have a few grains that are large enough to see, but most of them will be too small to see individual minerals. ... The individual mineral grains are almost too small to see. Some extrusive rocks cool so quickly that they do not form any grains. Instead, they form a natural glass.
Answer:
The percentage of mass recover from recrystallization = 24.69 %
Explanation:
Given that
Initial mass of crude acetanilide = 166 gm
The mass after recrystallization = 125 gm
The mass recover from recrystallization= 166 - 125 gm
The mass recover from recrystallization= 41 gm
The percentage of mass recover from recrystallization can be find as
The percentage of mass recover from recrystallization = 24.69 %
