Answer: 2 kg.
Explanation: Kinetic Energy is expressed as the product of mass and squared of velocity over two KE=1/2 mv² . Derive the following expression for mass. m=2KE/v² then substitute the values 2(225J)/ (15 m/s)² =2kg
Answer:
D. Malleability
Explanation:
Gold is made up of the element Au and it is a metal.
Pyrite is iron sulfide and it is a non-metal.
- They have very similar appearance to such an extent that pyrite is widely called the fool's gold.
- To distinguish between the two, we simply explore their metallic properties.
- Gold is malleable. Pyrite is not. It will crumble under pressure.

What is Electronic Configuration?
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics as well as quantum chemistry. For instance, the neon atom's electron configuration is 1s2 2s2 2p6, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells. According to electronic configurations, each electron moves independently within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants as well as configuration state functions are used to mathematically describe configurations.

Answer:
In organic chemistry oxidation is the gain of oxygen atoms by any carbon atom or molecules.
Explanation:
Oxidation can be defined in multiple ways
1- Loss of electron
2- Increase in oxidation number
3- Loss of hydrogen
4- Gain of oxygen atoms
The last definition is the earlier one in organic chemistry.
