'Impulse' is a change in momentum.
Momentum = (mass) x (velocity)
Final momentum = (45 x12) = 540 kilogram-meters/second
Original momentum = (45 x 15) = 675 kg-m/sec
Change in momentum = -135 kg-m/sec
The impulse required is 135 kg-m/sec in the direction
opposite to the way the object is moving.
Answer:
i can't see the picture, it is blocked off, can you write down your question?
Explanation:
The answer is C because you need non running hamsters to compare running hamsters with.
Protein has 4 cals carbs have 4 too. Fat however has 9.
Answer:
The weak nuclear force is one of the fundamental forces:
Is a force that is responsible of some radiative phenomenoms, like the beta decay.
The intensity is way smaller than the one of the strong interaction, but this is because it acts in a way smaller range. And this can produce atractive and repulsive interactions.
So options D and B can be discarded.
And this force can be repulsive or attractive depending on the phenomena, so the options that are wrong are A and B, because the interaction is both things, not only one.
