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

The non- living things that marine biologist study is everything from algae to the largest whale.Basically anything in the ocean, living or not they will still study them.
They are involved in a chemical digestion.
Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. It begins in the mouth when food mixes with saliva which contains enzyme salivary amylase that breaks down carbohydrates. It also occurs in the stomach where HCl and pepsin forms chyme and small intestine especially in the duodenum.
Answer:
No, it has too many variables or possible changes.
Explanation:
If you carried out an experiment or research on something, you have to given the same environmental and soil conditions to the factors. In this experiment, Kevin put the first plant in large pot and the other two plants in the field conditions. For performing correct experiments, Kevin put all the plants in separate pots or in the field conditions.
