Answer:
2.5 g/
Explanation:
The problem is asking for "density," so we have to know its formula first before we can solve.
Density (ρ) =
We know the mass of the cube (21.6g) but we don't know its volume. Let's check out the formula for volume.
Volume = length x width x height
Let's substitute the values.
Volume = 1.2 cm x 2.4 cm x 3 cm = 8.64
Now that we have the volume, we can already solve for the density of the cube.
Density = = 2.5 g/
Answer:
Scapular protraction and rotation.
Explanation:
The serratus anterior muscle is originated from the sides of the chest and originates from the 1 to 8 ribs. The long thoracic nerve innervates in the serratus anterior muscle.
This muscle inserts at the medial border of the scapula. The contraction of this muscle results in the scapular rotation and pulls the scapula towards the thorax. The anteversion of the arm and the scapular protraction is also caused by serratus anterior contraction.
Thus, the correct answer is option (2).
The answer to this would be a. true
