Answer:
3500 m
Explanation:
To find the horizontal displacement of the box of supplies, we just need to analyze its horizontal motion.
The horizontal motion of the box is a uniform motion with constant velocity, since there are no forces acting along this direction. Therefore, the horizontal displacement is given by
where
is the horizontal velocity
t is the time
The horizontal velocity of the supplies is the same as the plane, therefore
So, since the time of flight is
t = 17.5 s
The horizontal displacement is
Answer:
after 38.8 years it will double
correct option is D 38.8 years
Explanation:
given data
population grows rate = 1.8%
to find out
how many years will it take to double
solution
we consider here initial population is x
so after 1 year population will be = (100% + 1.8% ) x = 1.018 x
and after n year population will be =
so it will double
2x =
take log both side
log 2 = n log (1.018)
n =
n = 38.853
so after 38.8 years it will double
correct option is D 38.8 years
