Answer:
B
Explanation:
the reason the small turtle has more momentum is because it was less an example is I have two rocks a rock that weighs 1 oz and another rock that weighs half a pound the one that is half a pound Falls faster in the one that weighs an ounce Falls last hopefully that makes sense
Answer:
Impulse = 10.36 kg m/s
average force = 172.667 N
Explanation:
given data
mass = 0.280 kg
speed = 15.0 m/s
speed = 22.0 m/s
to find out
impulse and magnitude of the average force
solution
we know that Impulse is change in momentum that is
initial momentum = mass × speed ..........1
initial momentum = 0.28 × (15)
initial momentum = 4.2 kg m/s
Final momentum = mass × speed ..........2
Final momentum = 0.28 × (-22)
Final momentum = -6.16 kg m/s
so now we get Impulse that is
Impulse = 4.2 - (-6.16)
Impulse = 10.36 kg m/s
and
average force will be
average force = impulse ÷ time
average force = ![\frac{10.36}{0.060}](https://tex.z-dn.net/?f=%5Cfrac%7B10.36%7D%7B0.060%7D)
average force = 172.667 N
Efficiency of heat engine is determined by the ratio of difference in temperature of cold from hot reservoir to the temperature of hot reservoir over temperature of hot reservoir.
