Ignore my answers but someone give me something to put on here using these graphs i made using a moving man or whatever on the right bottom it asks "explain the scenario you acted out using the computer and your results. include the position time graph and the velocity time graph" literally all i did was let the dude move and a constant slow velocity of 1 and a constant quick velocity of 10

What property is a characteristic of a substance that can be observed and does not change the identity of the substance

Part a constants huck finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion what is huck's velocity (speed and direction) relative to the river bank? express your answer to three significant figures and include the appropriate units. relative to the shore)

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
