Answer:
During its trajectory the cannon ball will have kinetic and potential energy
E = KE + PE
The maximum value of PE will occur when the cannon ball was fired straight up - for other trajectories PE will be less because of translational KE
So E = M g h = 1/2 M v^2 for maximum height
h = v^2 / (2 * g) = 400 / (2 * 9.8) = 20.4 m
-- The greatest common factor of 2525 and 3535 is 5.
-- So the greatest possible number of teams is 5.
-- Each of the five teams will have 505 girls and 707 boys.
-- Rafaela is a superwoman ! She's handling more kids in that class than there were in my whole high school !
She has 6,060 students in her class, so I'm not surprised that she wants to divide the class up into smaller groups.
But come on ! She's going to form 5 teams, and she thinks that her job will be easier that way, because each team will have 'only' 1,212 students on it !
And these are all in one class ! If Rafaela is a physical education teacher, then SURELY she's teaching more than one class !
Or maybe not. I'll betcha whenever Rafaela is teaching her physical education class, all the other teachers are taking it easy, because Rafaela is responsible for every student in the school that hour.
And possibly several OTHER schools in town too.
Atmospheric pressure is caused by the weight of the atmosphere pushing down on itself and on the surface below it.
Pressure is defined as the force acting on an object divided by the area upon witch the force is acting.

Among the choices, I think the best answer to how semantic and episodic memories differ is that one remembers general ideas, and the other remembers specific events. Episodic memory refers to one's memory of his/her experiences of a specific event. On the other hand, semantic memories refer to one's memory of facts or general knowledge.
