A graph titled velocity versus time has horizontal axis time (seconds) and vertical axis velocity (meters per second). A line runs from 0 seconds 5 meters per second to 5 seconds 25 meters per second. What is the initial velocity of the object represented by the graph? m/s.

How to tell if two objects are in thermal equilibrium 1.the objects have the same temperature 2.the objects are the same size 3.the objects are touching each other 4.the objects temperatures are changing

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion

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.
