The velocity of a particle moving along a line is a function of time given by $v(t) = \frac{23t^2}{t^2+1}$. Find the distance (in units) that the particle has traveled after $t = 3$ sec.
A conservative force where x is in meters, acts on a particle moving along an x axis. The potential energy U associated with this force is assigned a value of 27 J at x = 0. (a) Write an expression for U as a function of x, with U in joules and x in meters. (b) What is the maximum positive potential energy? At what (c) negative value and (d) positive value of x is the potential energy equal to zero?
How do active and passive transport differ? Active transport requires the molecules moving to have energy, while passive transport does not. Active transport is always faster than passive transport. Active transport works against the chemical or concentration gradient, while passive transport works with it. No channels are needed in passive transport.
