In a sedimentary rock, small rounded particles indicate a a) long distance and long travel time. b) long distance and short travel time. c) short distance and long travel time. d) short distance and short travel time

A) long distance and long travel time.

Explanation:

Sedimentary rocks are the rocks which are created by the accumulation or the deposition of minute particles as well as subsequent cementation of the  mineral or the organic particles on floor of the bodies of the water at the  surface of the Earth.

Sediment Maturity is the duration of the time that sediments have been in sedimentary cycle. Texturally, mature sediments are that which are well rounded, (the process of rounding for the sediments increases with the transport distance as well as the time) as well as well sorted (the process of sorting for the sediments gets better as the larger clasts are astray and the smaller clasts are carried away , which also means the sediments travel longer distance).

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
