Answer:
n=4
Step-by-step explanation:
7n-3n=16
4n=16
n=16/4
n=4
A cross section is the shape we get when cutting straight through an object. In geometry it is the shape made when a solid is cut through by a plane. cylinder cross section.The cross section of this circular cylinder is a circle.
Because it has more mass so with less mass it accelerates faster. That is newtons 2nd law of motion.
20100 = 16000 * (1.02)^ t
20100/16000 = 1.02^t
1.25625 = 1.02^t
log 1.25625 = t * log 1.02
t = log 1.25625 / log 1.02
= 11.5
