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 = ![\frac{change in velocity }{time}](https://tex.z-dn.net/?f=%5Cfrac%7Bchange%20in%20velocity%20%7D%7Btime%7D)
F = m x ![\frac{V}{t}](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7Bt%7D)
V is the velocity
t is the time taken
F =
= 106.5N

The correct answer to the question above is cytoskeleton. Microtubules, microfilaments, and intermediate filaments make up the cytoskeleton, which lies beneath the plasma membrane and provides support, movement, and shape for the cell. These structures definitely form cytoskeleton for the support and structure.
Answer:
Birds require high levels of oxygen and, therefore, high rates of gas exchange due to flight demands. Avian resting oxygen consumption is high compared to that of mammals and other vertebrates, and this increases even more during the flight.
Explanation:
Compared to mammals, birds have specific adaptations of the respiratory system that result in higher levels of oxygen exchange.
