Take 85 points PLEASE Help Me A galvanic cell consists of an SHE (as the left-hand electrode) with standard potential equals to -0.76 volt. It has a rod of zinc dipping into a solution of zinc ions at 298 K gave measured emf of -0.789volt and s is 0.059.
What is the activity of the zinc ions? use these equation E=E°+s log[ion]​

Jasmine is diving off a 3-meter springboard. her height in meters above the water when she is x meters horizontally from the end of the board is approximated by the equation h=-x^2+3x+3. what is the maximum height jasmine will reach on her dive?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

Observations show that interstellar clouds can have almost any shape and
