Making rough estimate of physical quantities is useful because it allow us to have an idea of how big or small a quantity is, it gives us the near result of the real quantity a matter contains. The approximate quantity obtained will give us information about the size of the quantity.
When applying rigid-body mechanics to the study of human beings, the assumption made is Option B.The body does not deform by bending, stretching, or compressing.
<u>Explanation</u>:
Rigid body mechanics is a body in which the gap between any two points will be constant in time, despite of external forces. The body cannot be deformed at any circumstances be it under application of any force. The forces acting over the body gets divided into two groups one is external, which shows the action of different bodies on the rigid body under force and internal force that binds the body together making it rigid. Body changes its motion only in case of pull against some external object.
Answer:
Environmental Scientists can use GPS tagging
Explanation:
Positive impacts of genetic engineering:
• New products are created such as food with higher nutrition values, drugs that are more effective and safer
• Disease prevention (“correcting” the genetic mutation, or removing disease-causing gene)
Negative impacts of genetic engineering:
• irreversible side effects, for example resistance of bacteria or introduction of viruses in human cells
• abusing like change specific traits that are not connected with diseases, create human outcomes that are ethically questionable.
The only independent variable in this experiment is the amount of nitrogen Sarah uses. All of the other variables are dependent on other factor and processes, but Sarah controls the amount of nitrogen that she uses for each plant.
