two batteries of 7 volt and 13 volt and internal resistance 1 ohm and 2 ohm respectively are connected in parallel with the resistance of 12 ohm find the current through each branch of circuit and the potential difference across 12 ohm resistance

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

Which component of the earth’s atmosphere is decreased due to photosynthesis?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
