Compare the densities of two objects that have the same volume, but one feels heavier than the other.

motikmotik

We know, density = Mass / Volume
It represents density is directly proportional to mass and indirectly proportional to volume. So, at a constant volume, object with larger density will appear more heavier than that of object with smaller density.

In short, Heavier object will have the higher density than the other.

Hope this helps!

A model airplane is flying horizontally due north at 44 mi/hr when it encounters a horizontal crosswind blowing east at 44 mi/

Alik [6]

Explanation:

Let i, j and k represents east, north and upward direction respectively.

Velocity due north, $v_a=44j\ mi/hr$

Velocity of the crosswind, $v_w=44i\ mi/hr$

Velocity of downdraft, $v_d=-22k\ mi/hr$ (downward direction)

(a) Let v is the position vector that represents the velocity of the plane relative to the ground. It is given by :

$v=44i+44j-22k$

(b) The speed of the plane relative to the ground can be calculated as :

$v=\sqrt{44^2+44^2+22^2}$

v = 66 m/s

Hence, this is the required solution.
