Answer:

Gravitational Force

Explanation:

3 0

The force of gravitation between the charged particle is the force which is being ignored by the scientist while studying the atom as it is very small in comparison to other forces in the atom

<u>Explanation: </u>

The gravitation force between the atoms are very small or you can say it is negligible to be taken into consideration, as the values as small as these procure errors and difficulties in calculation or derivation, therefore are being ignored by the scientist.

The gravitational force between the charged particles are extremely small due to the fact that it depends upon the masses of the object and masses of charged particles in the atom are small and so force is small too.

A 25-kg child sits at the top of a 4-meter slide. After sliding down, the child is traveling at 5 m/s. How much PE does he start
Semmy [17]

Daniddmelo says it right there, don't know why he got reported.

The potential energy (PE) is mass x height x gravity. So it would be 25 kg x 4  m x 9.8 = 980 joules. The child starts out with 980 joules of potential energy. The kinetic energy (KE) is (1/2) x mass x velocity squared. KE = (1/2) x 25 kg x 5 m/s2 = 312.5 joules. So he ends with 312.5 joules of kinetic energy. The Energy lost to friction =  PE - KE. 980- 312.5 = 667.5 joules of energy lost to friction.

Please don't just copy and paste, and thank you Dan cause you practically did it I just... elaborated more? I dunno.

Bird bones have air pockets in them to reduce their weight–this also gives them an average density significantly less than that
Ksenya-84 [330]

Answer:

39.4 g

39.4 cm³

1.09137 g/cm³

Explanation:

\rho = Density of water = 1 g/cm³

Mass of water displaced will be the difference of the

m=43-3.6\\\Rightarrow m=39.4\ g

Mass of water displaced is 39.4 g

Density is given by

\rho=\dfrac{m}{v}\\\Rightarrow v=\dfrac{m}{\rho}\\\Rightarrow v=\dfrac{39.4}{1}\\\Rightarrow v=39.4\ cm^3

So, volume of bone is 39.4 cm³

Average density of the bird is given by

\rho=\dfrac{43}{39.4}\\\Rightarrow \rho=1.09137\ g/cm^3

The average density is 1.09137 g/cm³
