Stays lined up with North Star
It mimics the real world accurately
Explanation:
Experiments conducted in the field clearly presents the real world at it is to the scientist. Hardly can any part be controlled precisely and this gives a near to perfect scenario.
- In the laboratory, for example, an organism is isolated from its environment and might not fully display its natural instinct and physiological capabilities.
- Most laboratory set up are driven towards a model instead of real life settings.
- The laboratory is more controlled and less varied and might truly represent the real world. It will only portray a part of the real world and series of further tests might have to be carried out to have a better model.

30 Grams would be your answer (I took the test and got it right)
Answer:
10 m/s
Explanation:
Kinetic energy=
mv² where m is mass and v is velocity.
We have to make v the subject so we should rearrange the equation
K=
mv²
v²=
(use algebra)
v²= 7/0.5×0.140
v²=100
v=√100
v=10 m/s
We can confirm this by using the kinetic energy formula.
K=
×0.140×10²
K= 7 J
Hence it is proved that velocity is 10 m/s
