look at the image for the question and

respond in less than 5 minutes i need

fish: +10 N and -10 N

bottom of fish tank  +70 N  and -70 N

leg of the table +120 N and -120 N

Explanation:

arrow at the fish, downward: -10 N (down is negative, 10 N is the force exerted by the fish)

arrow at the fish, upward: +10 N (it must be in equilibrium with the previous one)

arrow at the bottom of the fish tank, downward: -70 N (down is negative, 70 is the addition of the forces exerted by the fish, 10 N, the aquarium, 20 N, and the water, 40 N)

arrow at the bottom of the fish tank, upward: +70 N (it must be in equilibrium with the previous one)

arrow at the leg of the table, downward: -120 N (down is negative, 120 is the addition of the forces exerted by the fish, 10 N, the aquarium, 20 N, the water, 40 N, and the table, 50 N)

arrow at the leg of the table, upward: +120 N (it must be in equilibrium with the previous one)

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
