A beaker weighs 0.4N when empty and 1.4N when filled with water . What does it weigh when filled with brine of density 1.2g/cm3 . Density of water is 1.0g/cm3). solve it n give me the answer​

Which feature of a heating curve indicates a change ofn state

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
