Find Acceleration due to gravity. Procedural Instructions:
You will need to jump vertically and mark another horizontal line (still with your hands stretched up) on the white sheet. Label this as h. Before doing this, have another member record your time (from jumping up to returning to the floor). Upon his/her signal, he/she will start the timer at the same time that you jump. He/she should stop the timer upon your return to the floor. Record this in your data table.
Fill up the table and use your data to find the experimental g of each member. Compute for the mean g of the group. Refer to the white board for the correct formula to be used.
Compute for the percentage error of your mean experimental g. Refer to the white board again for the correct formula to be used.

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.
