Given: F = m·a, an acceleration due to gravity of a = 32.2 ft/s2 , and an aircraft mass of m = 3105.6 slug a. How much does the aircraft weigh?

b. How much force would be required to accelerate the aircraft at 5 ft/s2

Along a frictionless surface?

c. Given that kg = 2.205 lb, what is the mass of the aircraft in kg?

d. Given that 1 N (Newton) = kg . m/s2 (F = m·a) and that the acceleration of gravity in the Metric System is 9.81 m/s2, how many Newtons does the aircraft weigh?

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

State the below theories and give the name of the writer of the theory 1. wave theory 2. quantum theory 3. corpuscular theory 4. electromagnetic theory
