he liquid level in a glass thermometer rises as the temperature increases because Group of answer choices the volume expansion coefficient of glass is less than that of the liquid. the volume expansion coefficient of glass is the same as that of the liquid. the pressure in the thermometer decreases. the pressure in the thermometer increases. the volume expansion coefficient of glass is greater than that of the liquid.

Your town is considering building a biodiesel power plant describe at least two advantages and two disadvantages

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
