Answer:
Explanation:
The two triangles are similar what is the length of DE
Answer:
Negatively charged, to positively charged parts
Explanation:
Electrons are negative, negative is attracted to positive.
Answer:
The fundamental wavelength of the vibrating string is 1.7 m.
Explanation:
We have,
Velocity of wave on a guitar string is 344 m/s
Length of the guitar string is 85 cm or 0.85 m
It is required to find the fundamental wavelength of the vibrating string. The fundamental frequency on the string is given by :

Now fundamental wavelength is :

So, the fundamental wavelength of the vibrating string is 1.7 m.
this atom has nine electrons
Explanation:
since electrons are found outside the nucleus of an atom and they are negatively charged
The core difference is that heat deals with thermal energy, whereas temperature is more concerned with molecular kinetic energy. Heat is the transfer of thermal energy, whereas temperature is a property the object exhibits.
