Calculate percentage change in mass for chip 5

Answer:

The correct answer is - 14.41%.

Explanation:

Given:

The initial mass of chip 5 -

end mass of chip 5 -

Percent Change in Mass =  /

Formula used:

Mass Difference= Final Mass- Initial Mass

Percent Change in Mass = (Mass Difference/Initial Mass) *100

Solution:

Putting the value in the formula:

Mass Difference = 2.15 - 1.84

= 0.31

Percent Change in Mass = (0.31/2.15)*100

= 14.41

Thus, the correct answer is - 14.41.

Answer: -14.41 %

Explanation:

start of chip 5 the mass was 2.15 and towards the end mass of the beetroot chip it changed and the mass was 1.84 grams. the mass difference is 0.31 and i got this by doing 2.15 - 1.84 .

Black bears in the north hibernate mostly due to the scarcity of food during the winter months.
Prior to hibernation bears are foraging for food. They eat fruit, nuts, acorns, insects, and certain leaves and plants. They catch occasional small animals, but lack agility to catch most adult prey. In the months before hibernation black bears can gain up to forty pounds of fat per week.

Jorge is testing the effect of lead on child development. Based on his observations, he finds that the longer the children are exposed to lead-based paint, the higher the chance becomes that the children may develop behavioral problems. He has done repeated experiments, and his results are similar to the results of many other scientists.

Why is this scenario considered a theory rather than a hypothesis?

It is a testable scenario.
It is based on prior knowledge.
It is a well-tested explanation.
It is a factual statement.
