Question 2 A half litre bottle has a mass of 80g. It contains 500 cm
of liquid when full. The bottle is filled with olive oil of
density = 0.90 g/cm?.
a Calculate the mass of oil in the bottle.
b Calculate the mass of the full bottle.
Calculating volume
Ve can rearrange the equation for density to make volume its su
ke this:

When the velocity of an object is doubled, by what factor is its momentum changed? by what factor is its kinetic energy changed? a) the momentum is zero. b) the momentum is not zero. c) difficult to say.

What is a neurotransmitter involved in mood reward, addiction, and motor behaviors?

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
