1. identifying a question through observations. then a hypothesis is formed as a tentative explanation for the question. Third, experiments are performed to test the hypothesis. Finally, a scientific paper is written to explain the conclusions.

It transforms it to mechanical
Answer:
Approximately 
(assuming that the acceleration due to gravity is 
.)
Explanation:
Let 
denote the first piston's contact area with the fluid. Let 
denote the second piston's contact area with the fluid.
Similarly, let 
and 
denote the size of the force on the two pistons. Since the person is placing all her weight on the first piston:
.
Since both pistons fit into cylinders, the two contact surfaces must be circles. Keep in mind that the area of a square is equal to 
times its radius, squared:
.
.
By Pascal's Law, the pressure on the two pistons should be the same. Pressure is the size of normal force per unit area:
.
For the pressures on the two pistons to match:
.
, , and have all been found. The question is asking for . Rearrange this equation to obtain:
.
Evaluate this expression to obtain the value of , which represents the force on the piston with the larger diameter:
.
Answer:
Gravitational potential energy of the astronaut will change by a greater amount on the earth
Explanation:
Gravitational potential energy is expressed by the formula;
GPE = mgh
This means that the gravitational potential energy is directly proportional to the gravity(g)
Now, from constant values, gravity of moon is 1.62 m/s² while gravity of the earth is 9.81 m/s².
This means that if we plug in the values of g on the earth and g on the moon, the potential energy on the earth would be greater than that of the moon
Thus, gravitational potential energy of the astronaut will change by a greater amount on the earth
Answer:
The principles that govern heredity were discovered by a monk named Gregor Mendel in the 1860s. One of these principles, now called Mendel's Law of Segregation, states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization. ... Organisms inherit two alleles for each trait.
