The description of the problem is a bit ambiguous as "<span>increasing at the rate of </span>3 inches more than the time" can be interpreted in many ways. Assuming the increase rate is the (3+t) per second and as it expands for 3 seconds, then the diameter of the sphere would be:
d= (3 + t)*t
d= 3t + t^2= 18
r= 1/2 d
r= 1/2*18= 9
volume= 4/3 * pi * r^3
volume= 4/3 * pi * 9^3
volume= 4/3 * pi * 729= 972 pi cubic inches
That's really going to depend a lot on what materials he plans on using.
Answer:
The presence of strong intermolecular forces favors a condensed state of matter. liquid or solid), while very weak intermolecular interaction favor the gaseous state.
Answer:45.24 m/s
Explanation:
Given
Height of Building h=24 m
Range of ball R=100 m
Considering Vertical motion of ball
using
initial vertical velocity is zero therefore
Now considering Horizontal Motion
, as there is no horizontal acceleration
