Answer: The net displacement is 6.40meters
Explanation:
Answer:
Explanation:
While traveling through space, asteroids sometimes collide with each other and break up into smaller fragments. Comets shed dust as they roam the solar system. These 'break ups' result in numerous small particles and fragments, called meteoroids, which orbit the sun. ... Thus a meteor, or shooting star, is formed.
Answer: 
Explanation:
According to Newton's law of universal gravitation:
Where:
is the module of the force exerted between both bodies
is the universal gravitation constant.
and 
are the masses of both bodies.
is the distance between both bodies
In this case we have two situations:
1) Two bags with masses 
and mutually exerting a gravitational attraction 
on each other:
(1)
(2)
(3)
2) Two bags with masses 
and 
mutually exerting a gravitational attraction 
on each other (assuming the distance between both bags is the same as situation 1):
(4)
(5)
(6)
Now, if we isolate 
from (3):
(7)
Substituting found in (7) in (6):
(8)
(9)
Simplifying, we finally get the expression for in terms of
:
Answer
rate of current = (1/x) mph
Explanation
let the distance from <span>Greentown to Glenavon be y miles and the rate of current be x mph.
y = (15+x)g
y = 15g+gx .........................................(1)
The distance from </span><span>Glenavon to Cambria = (y-2)
y-2 =(15-x)g
y-2 = 15g-gx
y = 15g - gx + 2 ....................... (2)
equation equation (1) and (2)
15g + gx = 15g - gx + 2
2gx = 2
dividing by 2g both sides we get,
x = 1/2g mph
