Mass number = protons + neutrons

If you have the # of protons and the mass #, subtract the number of protons from the mass number to get the number of neutrons.

If you have the number of neutrons and the mass number, subtract the number of neutrons from the mass number to get the number of protons.

<h3>Mass number:</h3>

The element's mass number is nothing but the sum of total number of neutrons and protons present in the element's nucleus. For example, if the mass number of nitrogen is 14, it means that there are 7 number of protons and 7 number of neutrons in the nucleus of the nitrogen.

The relationship between the number of proton and the neutron with that of mass number is that, the latter gives the count of the former. On contrary, the atomic number denotes the weight of the atom.

What are the three main processes that make up aerobic respiration? Name each process, provide a brief description of the proces
IRISSAK [1]

Answer:  

Aerobic respiration is a process glucose produces energy in the presence of oxygen. In this process glucose is oxidized to produce carbon dioxide, water and energy in the form of ATP.

C₆H₁₂O₆ + 6O₂ = 6CO₂ + 6H₂O + Energy (ATP)

Three main processes that make up aerobic respiration are:

1. Glycolysis:  it takes place in the cytosol of the cell. Here, glucose is oxidized to form three carbon molecule pyruvate. This process produces energy in the form of 2 ATP molecules and 2 NADH molecules. These NADH molecules carries 2 energy electrons these electrons are utilized by the electron transport chain.

2. Kreb's cycle: it takes place in the cytoplasm and mitochondria of the cell. Here, the molecules of pyruvate produced during glycolysis is utilized to produce ATP.

3. Electron transport chain:  glucose is not entirely converted into ATP. The NADH molecules produce during glycolysis  produces 2 energy electrons these electrons are taken up by electron transport chain in the mitochondria inner matrix. A proton gradient develops across the matrix after donation of electrons to electron transport chain. This gradient in turn produces energy in the form of ATP.

terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for
svetlana [45]

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}

  F = m x \frac{V}{t}

V is the velocity

t is the time taken

   F = \frac{75  x  4.4}{3.1}   = 106.5N
