a 250 g block of ice is removed from the refrigerator at -8.0°C. how much thermal energy does the ice absorb as it warms to room temperature (22°C)? (the heat of fusion of water is 334) (specific heat of ice is 2.05 joules/gram) (specific heat of water is 4.184 joules/gram) (besties pls help, this is like my third time posting this and no one answered 3)

Agas is contained in a vertical, frictionless piston–cylinder device. the piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. a compressed spring above the piston exerts a force of 190 n on the piston. if the atmospheric pressure is 95 kpa, determine the pressure inside the cylinder.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
