Answer:
Impulse. Impulse is when a force is applied to an object for an amount of time.
Explanation:
It can't be momentum because momentum is the motion of a moving body, that is measured as a product of its mass and velocity.
It' cant be inertia because inertia is when an object doesn't move/ it does nothing as well as an object remaining unchanged.
And it can't be acceleration because acceleration is when how fast an object can go/ there velocity.
And that leaves us with impulse, so that's the correct one.
Hope this helped!
If it is a matter of which way you are going you could lean forward. It would help to put all the weight opposite of where you are falling.
power = (voltage) x (current)
17 w = (5 v) x (current)
current = (17 w) / (5 v) = 3.4 Amperes
Answer:
57,42 KJ
Explanation:
By a isobaric proces, the expresion for the works in the jpg adjunt. Then:
W = Pa(Vb - Va) = Pa*Vb - Pa*Va ---(1)
By the ideal gases law: PV=RTn
Then, in (1): (remember Pa = Pb)
W = R*Tb*n - R*T*an = R*n*(Tb - Ta) --- (2)
Since we have 1 Kg air: How much is this in moles?
From bibliography: 28.96 g/mol
Then, in 1 Kg (1000 g) there are:
n = 34,53 mol
Finally, in (2):
W = (8,3144 J/K.mol)*(34,53 mol)*(500K - 300K) = 51 419,9 J ≈ 57,42 KJ
