jessica and Linda, level 200 students conducted an experiment to estimate the acceleration due to gravity. in the experiment, Jessica drops a ball at a distance of 1.5metres above the floor. Linda measures the time to fall and obtains an estimate of 0.5s. what do they estimate the acceleration due to gravity to be? (b) let s be the ball's position relative to the floor. using the value of acceleration on due to gravity that they obtained and assuming the ball is released at t=0, determine s (in metres) as a function of time.

Which component of the earth’s atmosphere is decreased due to photosynthesis?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
