Assuming the input of energy continues for another 2.5 seconds, where will the particle be? equilibrium positive maximum negative maximum cannot be determined

How do you tell if someone actually cares about you? and just say they do?

More solar radiation is absorbed by earth’s surface than by

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
