Ascientist investigating the amount of force needed to perform a bicep curl with a 10 lb weight is studying which level of organization?

He studying the: Organ system level of organization

Organ system level

Explanation:

The levels of organisation of a body includes cells, tissues, organs and organ systems. These levels of organization build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems. Organ system level involves a group of organs that contribute to specific functions in the body. In the case above the level of organisation the scientist is studying is Organ system level because performing that particular tasks ( stated in the question) involves the contribution of more than one organ(requires a group of organs).

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
