Answer:

kinetic energy

Explanation:

When the object is released, the gravitational potential energy is gradually converted into kinetic energy as it picks up speed.

How many number of orbitals are in Potassium (K)?<br><br> 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1
Doss [256]

Explanation:

Each orbital can only carry at most 2 electrons wih opposite spins.

The first 3 shells are fully filled, giving 9 orbitals.

There is an extra electron in 4s, which gives another orbital. (even though it is not filled yet)

Hence there are 10 orbitals.

Put these different types of radiation in order from MOST to LEAST penetrating.
Naily [24]

Answer:

C. Gamma > beta > alpha

Explanation:

<u>Alpha rays</u> : These are positively charged  and have mass 4u. These contain high energy Helium nucleus with 2 proton and 2 neutron.

These are heavier and maximum charged than beta and gamma particles.They have low velocity,least penetration power (can't travel more than 10-18 cm).

<u>Beta rays</u> : They are negatively charged and have negligible mass.

On emmission of beta particle, neutron is divided into proton and electron. They have less mass and very high velocity, so their penetrating power is more than alpha particles.

<u>Gamma rays</u>: These are parts of electromagnetic spectrum and travel with the speed of light (maximum velocity).Gamma rays do not have mass have maximum penetrating power.

A graduated cylinder is filled 25.0 mL with water and a piece of granite is placed in the cylinder, displacing the level to 37.2
kvv77 [185]

The volume  of the granite piece  in Cm³  is 12.2 cm³

 <u><em>calculation</em></u>

volume of granite = (volume of cylinder after placing granite - volume  of  cylinder  before  placing  granite

 = 37.2 ml - 25.0 ml = 12.2 ml


convert ml  to Cm³

that is 1 ml = 1 cm³

       12.2 ml =  ? cm³

<em>by cross  multiplication</em>

=(12.2 ml x 1 cm³) / 1 ml = 12.2 cm³
