The trip took about 22 days, and the fish consumed energy at a rate of 2.0 W for each kilogram of body mass. Part A What is the total energy used by a 2.0-kg salmon while making this 22-day trip?

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
