You may have noticed that in spite of carefully measuring and calculating, the values for the specific heat you determined experimentally do not match the published values for those concentrations of propylene glycol solutions. Let's explore why. 1. Rosa suggests a source of error: Some of the energy from the heating coil is lost because the insulation of the container is not perfect. What type of error will this cause

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

second mirror gathers light from a faraway object and reflects it to another mirror. - a.

6/12=1/2

step-by-step explanation:

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
