4. Fig. shows apparatus that demonstrates how a coin and a piece of paper fall from rest under gravits piece of paper o coin tube containing air A Fig. 4 (a) State the initial value of the acceleration of the coin as it falls from rest. Initial velocity of the will be o when fa Coin (b) The coin and paper are at the positions shown in Fig. 4. Explain, in terms of the forces acting, why (i) the paper falls with constant speed,​

1. a net force of 100 newton’s is applied to a wagon for 5 seconds. this causes the wagon to undergo a change in momentum of

Calculate the work done by an external agent during an isothermal compression of 1.00 mol of oxygen from a volume of 22.4 l at 10∘c and 1.0 atm pressure to 16.8l

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.
