Water, h2o, is a molecule made of oxygen and hydrogen. the bonds that hold water molecules together are due to shared and known as covalent bonds. a) electrons b) neutrons c) photons d) protons

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Ineed the answer to question 1 , i’m desperate

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?
