Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that
mixas84 [53]

Answer:

mas of water displaced = 41.4 g

Explanation:

Weight in air = True weight = 45 g

Apparent weight = 3.6 g

Apparent weight = True weight - Buoyant force

Buoyant force = 45 g - 3.6 g = 41.4 g

Weight of water displaced = Buoyant force

Weight of water displaced = 41.4 g dyne

mas of water displaced = 41.4 g

Put the following stages of star formation into the proper sequence from earliest to latest:
BaLLatris [955]

C → A → E → D → F → H → G → I → B

Explanation:

Put into the proper order, the following are the stages of star formation  from earliest to latest:

Massive, rotating, amorphous interstellar cloud collapses and fragments → Infalling material forms a hot and luminous protostar at the center of the disk → Gravitational contraction causes protostar to shrink and heat as it descends the Hyashi track → As the shrinking protostar heats up, hydrogen is ionized and a magnetic field forms → Magnetic bipolar outflows begin along rotation axis as the magnetic field forms → As bipolar outflows become stronger, powerful T-Tauri winds start clearing the nebula before the onset of nuclear fusion → Shrinking cloud collapses into a flat disk shape → Onset of nuclear fusion in the core occurs around 15 million K → Newly-formed star settles onto the Main Sequence

Why unit of pascal is called derived unit?​
Annette [7]

Answer:

This is because it is derived from newtons and metres as shown in the expression;

Explanation:

pressure =  \frac{force}{area} \\  P= \frac{F}{A}  \\ P= \frac{newtons}{ {m}^{2} }  \\  = pascals

A car starts at zero and gets to 50 km/hour in 10 minutes. What is the initial velocity?
gladu [14]
The initial velocity is the speed and direction of the car at the beginning
of the event. 

You just said that the car "starts at zero".  You might mean that it starts at
"location zero".   But then you go on to tell us its speed after 10 minutes,
so it sounds like the "zero" at which it starts is zero speed.

In that case, its initial velocity is zero.
