Answer:
It is classified as a metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. Copper is a mineral used for our everyday use. It is limited and we have to use it wisely because it is not evenly distributed everywhere and also everyone needs it. Copper is element number 29 on the Periodic Table of Elements. It is also used it electronics and wiring.
hope this helped

20 degrees F! 0 degrees C is equivalent to 32 degrees F, so 20 degrees F is colder.
a.) Relative velocity = velocity of car B - velocity of car A
= 19 - 14
= 5 m/s
Hope this cleared your doubt, feel free to ask any question regarding this and have a nice day ahead! :)
Answer:
0.541 nm
Explanation:
The condition for maxima is,
Here, m=0,1,2,.....
And d is the slit separation, m is the order of maxima, 
is the wavelength.
Given that, the 17.3 eV electron posses a wavelength of
And the order of maxima is 
.
And the angle at which first order maxima occur is, 
.
Put these values in maxima condition while solving for d.
Therefore, the slit separation is 0.541 nm.
