A viewing window on the side of a large tank at a public aquarium measures 56 in. by 61 in. The average gauge pressure from the water is 2 psi. What is the total outward force on the window

Ineed the answer to question 1 , i’m desperate

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

What type of force holds atoms together in a crystal?
