Answer:
The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces. The more particles that hit the walls, the higher the pressure.
Answer:
16.25 m
Explanation:
we know that the equation pf parabola

from bellow figure the coordinate of parabola is (600,65) that is y=600 and x=65
putting the the value of y and x in the equation of parabola

k=0.0001805
now the equation is

we have to find the value of y at x=300m
so 
y=16.25 m
Could you maybe show us the diagram
Answer:
hello the answer is 47m/s
