Asmall fish (m = 0.5 kg) moving at 2 m/s is followed by a bigger fish (m = 5 kg) moving at 3 m/s. (show work)

a) what is the total momentum of this system before the big fish had its lunch?

b) what’s the momentum after lunch?

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?

Describe uniform velocity and variable velocity in short

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20
