2. step by step
formular w=p(volume1-volume2)
w= 1.0×10^5(0.0006-0.0004)
w= 40 J
Answer:
144Ns
Explanation:
Impulse is the product of force and change in time or a measure of the change in momentum. Mathematically, Impulse is given as
J = FΔt
Where
J = Impulse,
F = Force,
Δt = change in time.
Due to the varying force, we know that the impulse varies at different points in the motion. Hence, the Net Impulse will be the addition of the individual impulses, i.e.
J = ΣJᵢ
J = J₁ + J₂ + J₃
J = F₁Δt₁ + F₂Δt₂ + F₃Δt₃
=> J = (24*2) + (24*4) + (0*2)
J = 48 + 96 + 0
J = 144 Ns
Answer:
the correct would be c
Explanation:
a magnet will always have a north and a south so if you cut the magnet in half the north part would have a south on the opposite end and vice versa .
Answer:
For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.
