uppose a gas-filled incandescent light bulb is manufactured from regular glass and with atmospheric pressure in it at 20.00°C. Its average temperature when hot is 63.42°C. Neglecting any change in plume due to thermal expansion or gas leaks, its gauge pressure is calculated to be 0.1482 atm. The actual final pressure for the light bulb will be less than calculated because the glass bulb will expand. What will the actual final gauge pressure be, taking this into account? The coefficient of volume expansion for regular glass is 27 x 10-6/°C. (Give your answer to at least four decimal aces.) atm

Hi! I need help with finding the cross product of 2 vectors with only an i and a j but no z/k, can you please help? everywhere ive looked for help always has a z/k component and i dont know how to figure that out

An aquatic organism needs to be neutrally buoyant to stay at a constant depth. Fish accomplish this with an internal swim bladder they can fill with air that they take in from the water through their gills. One complication is that the pressure in the swim bladder matches that of the surrounding water, but the water pressure changes with depth. Because the volume of a gas is inversely proportional to pressure (as you may already know if you have studied the ideal-gas law), the volume of air in a fish's swim bladder decreases with depth unless the fish actively adds more air. ▼ Part A Consider a 3.9 kg freshwater fish whose tissues have an average density of 1050 kg/m³. To what volume in mL must the swim bladder be inflated for the fish to be neutrally buoyant at the surface? Express your answer in milliliters to two significant figures.

Large helium-filled balloons are used to lift scientific equipment to high altitudes. a) What is the pressure, in atmospheres, inside such a balloon if it starts out at sea level with a pressure of one atmosphere and a temperature of 10.0°C and rises to an altitude where its volume is twenty times the original volume and its temperature is -49.5°C ?  b) What is the gauge pressure, in atmospheres, in the balloon then? (Assume the atmospheric pressure is constant.)
