Which law might require you to do some math calculations?
Vadim26 [7]

Answer:

Law 2

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Hence, Law 2 might require you to do some math calculations.

For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.

Given the following data;

Mass = 20kg

Acceleration = 0.5m/s²

To find the force;

Force = mass * acceleration

Substituting into the equation, we have;

Force = 20 * 0.5

Force = 10 Newton.

Explain how cells specialize to form specific tissue and organs?
S_A_V [24]
<span>All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes. Scientists have been looking for ways to reverse the process, meaning turning specialized cells back into stem cells. Some success has been reported using different methods. The latest one uses a weak acid to stress the cells.</span>
