Answer:
6.136 mm
Explanation:
given,
frequency emitted by the bat = 5.59 x 10⁴ Hz
speed of sound = 343 m/s
smallest insect bat can hear will be equal to the wavelength of the sound the bat make.



λ = 6.136 mm
so, the smallest size of insect that bat can hear is equal to 6.136 mm
A. Getting a full set of valence electrons
Explanation:
The best description of the end result of chemical bonding for most atoms is the getting of a full set of valence electrons.
Atoms reacts with one another in order to complete valence electronic shell.
- The valence electron shell is the outermost energy level of an atom.
- It is from this energy level that electrons are lost or gained to form bonds.
- All atoms wants to be like the noble gases whose valence electronic shell is completely filled up
- This is the crux of chemical bonding
- The attraction that is produced from the interaction leads to bond formation

Answer:
m = 327.07 kg
Explanation:
Given that,
Kinetic energy of a motorcycle, E = 57800 J
Velocity of the motorcycle, v = 18.8 m/s
We need to find the mass of the motorcycle. The kinetic energy of an object is given by :

m is mass

So, the mass of the motorcycle is 327.07 kg.
Answer:
None of the above
Explanation:
When energy is converted from one form to another in a chemical or physical change, none will change. This is due to the law of conservation of energy. It states that the total energy of the system remains constant. It only changes energy from one form of energy to another. So, the correct option is (d) "none of the above".
