Answer:
Momentum of the bowling pin is 17kgm/s
Explanation:
P(initial of ball)=+30 kg m/s
P(initial of pin)=0 because its velocity is 0
P initial = P final
30= P(ball) + P(pin)
30=13+P(pin)
P(final of pin)=+13 kg m/s and P(final of ball)= 30-13=17kgm/s
Yes it does. But not always
Answer:
Change in Displacement
Explanation:
delta/triangle = change
x = displacement
formula (if needed): final x - initial x
I think the correct answer would be D. After cutting the solid object in half, the mass and volume are both divided by two, but the density remains the same. The mass and volume would change accordingly to satisfy the law of conservation of mass which states that mass cannot be created or destroyed. So, after dividing the object the sum of the mass of the two parts should be equal to the original mass of the object. This would also be the same for the volume of the objects. Density is the ratio of mass and volume and, since the mass and volume change accordingly, the value of the density would still be the same regardless of the object being divided.
