A scientist is using a calorimeter to determine the specific heat of an unknow substance. The sample lost 2457 J of energy to the water bath as
it cooled from 95.8*C to 29.6*C. If the sample has a mass of 95.2g, what is
the substances specific heat?

Unpolarized light falls on two polarizer sheets whose transmission axes are at right angles. a third polarizer is placed between the first two so that its axis makes a 52-degree angle with the axis of the first polarizer. a) what fraction of the incident light intensity is transmitted through the first polaroid? b) what fraction of the incident light intensity is transmitted through the second polaroid? c) what is the angle of polarization of the light that enters the third polaroid? d) what fraction of the incident light intensity is transmitted through the third polaroid. e) what happens if the middle polaroid is removed?

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass

Find the mass by adding the numbers from the three sliders
