Foliated rocks have bands, or layers( whatever you want to call it) unifoliated rocks don't have that I think.
Tangential speed --> speed of something that is moving in a circular path) of an orbiting object is:
V₍t₎ = ωr
V₍t₎ = tangential speed or velocity
ω = angular velocity
r = radius of the circular path
if time taken t is only given then use this formula to calculate the tangential speed:
V₍t₎ = 2πr/t, t is time taken < --
Answer:
a. food and drink.
Explanation:
Maslow’s hierarchy of needs as represented by a pyramid, has the most fundamental and basic needs placed at the bottom, which are physiological needs. They are followed by safety, love and belonging, esteem, and self-actualization.
