Try deducing Torriccelli's formula from the equations for position and velocity with respect to time:
2 = xo + vot + at
I
1
U = V0 + at.
Remember that the displacement is defined as the variation in the position
d=1 - 10
Hint:Remember that (a + b)2 = a² + 2ab + 62.

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
