Answer:
The magnitude of Adam's displacement is 0 m
Explanation:
Given;
Adam's distance from his home to the mall, d₁ = 1100m
then, his distance from the mall back to his home, d₂ = 1100m
Adam's displacement is given by;
Displacement = final position - initial position
Adam's displacement = d₂ - d₁
Adam's displacement = 1100 m - 1100 m = 0 m
Therefore, the magnitude of Adam's displacement is 0 m
Composition Is the property
Hello, some examples are Earth science, chemistry and Navigation science (don't know if there is called in this way).
In Earth Science we can talk about Geomagnetism.
In Chemistry, electrostatics and electrochemistry.
In Navigation science the compass.
Hope it helped.
We know the formulas for momentum and energy. But they both involve the mass of
the object, and we don't know the mass of the baseball. What can we do ?
It's not a catastrophe. The question only asks which one is bigger. If we're clever,
we can answer that without ever knowing how much the momentum or the energy
actually is. We know that both baseballs have the same mass, so let's just call it
' M ' and not worry about what it really is.
<u>Momentum of anything = (mass) x (speed)</u>
Momentum of the first baseball = (M) x (4 m/s) = 4M
Momentum of the second one = (M) x (16 m/s) = 16M
The second baseball has 4 times as much momentum as the first one has.
<u>Kinetic energy of anything = 1/2 (mass) x (speed squared)</u>
KE of the first baseball = 1/2 (M) x (4 squared) = 8M
KE of the second one = 1/2 (M) x (16 squared) = 128M
The second baseball has 16 times as much kinetic energy as the first one has.
