The given question tells you that a certain piece of wire has a mass = 2.0 g per meter
That means that if you consider a piece of wire that is 1 m in length, its mass will be equal to 2.00 g .
According to question,
Now, you know that
1 m = 100 cm
Mass of 2.00 g of copper will correspond to a wire that is a 100 cm long.
This implies that 0.28 gof copper will correspond to a wire that is
0.28 g * 100 cm / 2.0 g = 14 cm long
Hence, 14 cm of the wire would be needed to provide 0.28 g of copper.
Properties of Copper :
High conductivity and ductility.
Non magnetic.

The answer is a traveling wave
Travelling waves are temporary waves and these occur for a very short duration and move with constant speed. It is represented by an infinite rectangular waves. The crest of travelling wave move in wave propagating direction. Mathematically a periodic travelling wave is a one dimensional space that moves constantly with unvarying velocity through some medium.
Answer:
1 and the element is hydrogen (there is an exception for the octet rule for the element hydrogen) hope this helps
Explanation:
Answer:
The answer to your question is: B
Explanation:
Physical properties are properties that occurs in matter but there is not change in the composition.
A. Solid ice can be very brittle. This is a physical property.
B. Water can form hydrogen and oxygen gas under electrolysis conditions. Here there is a change in the composition of matter, this is an example of chemical property
C. Water can freeze solid at 32 degrees Fahrenheit.
This is a physical property.
D. Liquid water can turn into steam in a heated tea kettle. This is a physical property
E. none of the above This option is wrong because option B is correct.
What? Why does it have a question mark it makes no sense because there isn’t any options and you didn’t explain what the question is about.
