Answer:
electrons
Explanation:
metals do what is called metallic bond
Answer:
1.Velocity and pitch
2.The unit of vibration is hertz. The number of oscillations of an oscillating body per second is known as frequency. Complete step by step answer: The time taken by a vibrating body to complete one vibration is time period.
3.Frequencies above 20,000 Hz are known as ultrasound.
They certainly can. However, they have other groups that are used to classify a compound.
I believe the correct answer is C. The amount of catalyst is the same at the end as at the beginning of the reaction. Catalysts can't be consumed by the reaction thus is not D.
we have,
wavelenght=c/f
where c= 3×10^8 m/s
f=6.3×10^12 s^-1
so wavelength=(3×10^8)/(6.3×10^12)
=0.476×10^-4 m
