    Trade limit specialisation NEED HELP

    This is the question.. Suppose that by devoting all of its resources to the production of A, the nation of Econia can produce 50A. By devoting all of its resources to the production of B, Econia can produce 25B. The comparable figures for the nation of Optima are 5A and 5B. According to the...

    How Do You Calculate Tension in a Two-Block Pulley System?

    can we tilt the diagram,61 degree clock wise such that the gravitational force that is acting on block b is 9.8m/s^2. and there will be a downward acceleration for block a? can we use that approach to solve this question as well?

    What role does a Bank play in the economy.

    a bank also creates money a central bank will impose a reserve ratio on bank, for example 0.1 ( which mean for every 10 dollar deposited, 1 dollar must go to the reserve) while doing that, they also create money in the process, the formula is 1xmultiplier. formular of multiplier = 1/reserve...

    Elastic Collision of Two Objects (2D)

    after we have this equation: let's call in 1 ->(17*32)+(35*12)=(17*x)+(35*y) we also use (V1i-V2i)=-(v1f-v2f) => 32-12+v1f=v2f -(2) sub equation 2 into 1 and we get the final answer am i correct? pls advice :D

    Need help on question Newton's second law

    hmm..thx for the reply! anyway,since my question didnt state anything about the forces,i think its ok for me not discuss about the forces. but for learning sake, so the force that is acting on the space shutter is <9.8 and it is a constant? am i right?
