106.5N
Explanation:
Given parameters:
Mass of cart = 75kg
Velocity = 4.4m/s
time taken = 3.1s
Unknown:
Force = ?
Solution:
To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".
F = m x a
F = force on body
m = mass of body
a = acceleration of the body
But we know that acceleration is the change in velocity with time of a body;
a = 
F = m x 
V is the velocity
t is the time taken
F =
= 106.5N

When salt and sugar dissolve in water it is a physical change. The chemical makeup of the salt and sugar are not changed.
Physical change
Decrease as the more frogs there are the more flies will be eaten so that means the flies will decrease.Also if the flie population gets low enough the frog population would shrink too to balance it.
