Answer:
the work that must be done to stop the hoop is 2.662 J
Explanation:
Given;
mass of the hoop, m = 110 kg
speed of the center mass, v = 0.22 m/s
The work that must be done to stop the hoop is equal to the change in the kinetic energy of the hoop;
W = ΔK.E
W = ¹/₂mv²
W = ¹/₂ x 110 x 0.22²
W = 2.662 J
Therefore, the work that must be done to stop the hoop is 2.662 J

Answer:
The scientific method helps test and arrive at conclusions for a variety of hypotheses that are created when studying environmental science.
Explanation:
What is the scientific method in environmental science?
The scientific method is a method of research with defined steps that include experiments and careful observation. One of the most important aspects of this method is the testing of hypotheses by means of repeatable experiments. A hypothesis is a suggested explanation for an event, which can be tested.
The answer that fits the blank is SOURCE REDUCTION. Source reduction refers to the prevention of further pollution by eliminating the source before this can produce the wastes. This helps in the reduction of pollution, thus reduces the amount of toxins brought by these wastes that may harm the environment.
