Inertia is an object's resistance to change in motion. In other words the difficulty in moving an object or stopping it from moving. A heavier car has more inertia than a lighter car because it's harder to move. A faster car has more inertia than a slower one with equal mass because it's harder to get it to stop.
So the more inertia a car has, the more dangerous it is in a collision.
the sodium chloride will be a crystal
it will have a giant crystal lattice
I think the gravity doesn't affect the mass of an object. Only it's weight can be compared
It is true that only half of the moon is always illuminated
by the sun. The reason why the moon
changes it phases is because Moon orbits around the Earth, and due to this some
areas of the half of the moon will not be lit by the sun.
Answer:
Explained below
Explanation:
For the geometric meaning, I've attached a parallelogram showing two vectors a and B and also the angle between them as θ.
We can see that the two vectors are adjacent to each other.
So the magnitude of the product of the two vectors is simply the area of the parallelogram which is base x height. Thus;
Magnitude = |a| sin θ × |b|
This can be rewritten as;
|a|•|b| sin θ
