    Upwelling rates in the ocean involving carbon and nitrogen

    This is a 3 part question that i have attempted to answer. I'm pretty sure I'm on the right track but i think i made 1 or 2 small mistakes along the way. the question states: The average depth of the ocean is 3.8km and the ocean surface area is 360x10^12 m^2. The average upwelling rate of deep...

    Solving this equation radioactive decay equation

    OK, so here's the problem. tell me what you think N and N0 should be. The youngest bottom waters in the North Atlantic had a [delta 14 C] value of approx -70o/oo (o/oo being parts per thousand). Bottom waters in the South Pacific have a [delta 14 C] value of -170o/oo, while bottom waters in the...

    Solving this equation radioactive decay equation

    I apologize if this is posted in the wrong forum. this may not be calculus but i would appreciate any help solving this equation radioactive decay equation is N=N0e^-(0.693t/T(1/2)) N is the current specific activity value, N0 is the initial specific activity, t is the time or age of the...

    Particle Collision: 3.00kg & 4.00kg Particles

    Particle Collision Two A collision occurs between a 3.00 kg particle traveling with velocity v = (-4.00 m/s) i + (-5.00 m/s) j and a 4.00 kg particle traveling with velocity v = (5.60 m/s) i + (-1.80 m/s) j. The collision connects the two particles. What then is their velocity in each of the...

    What is the tension in the string?

    forces act on blocks A and B, which are connected by a string. Force FA = (15 N) i acts on block A, with mass 5.0 kg. Force FB = (24 N) i acts on block B, with mass 6.0 kg. What is the tension in the string? Fa Fb -> -> [A]---[B]--> F=ma (15N+24N)=(5.0kg+6.0kg)(a)...

    Sunjamming: Solving Webassign Question on Mass, Force & Acceleration

    ok thanks c did work but a and b is really frustrating me. the two given numbers in the problem were 1100kg and 17 N. so the sig figs should be 2 right? and the units is m/s^2 ...(a) What is the magnitude of the resulting acceleration? 1.5e-2 m/s2 X wrong (b) If the craft starts from rest...

    Sunjamming: Solving Webassign Question on Mass, Force & Acceleration

    just wanted to double check with you on a webassign question. i feel like I'm doing it right but webassign doesn't like my answer... question 2 says A "sun yacht" is a spacecraft with a large sail that is pushed by sunlight. Although such a push is tiny in everyday circumstances, it can be...
