In order to fabricate a uniform wire that has a resistance of R = 0.500Ω from 1.00 g of copper and all the copper is to be used, the Length, L of the copper required is 1.82m.
<h3>What would be the length of the copper wire?</h3>
The length of the wire is obtained as follows:
Length, L = √R*m/e*d
where;
R is resistance and is equal to 0.50 Ω
m is mass of the copper and is equal to 1.00 g or 10⁻³ kg
e, resistivity of Copper = 1.7 x 10⁻⁸ Ω⁻¹m
density of copper, d = 8.92 x 10³ kg/m³
L = √(10⁻³ * 0.50/1.7 x 10⁻⁸ * 8.92 x 10³)
Length, L= 1.82m
In conclusion, the length of the wire is obtained from the mass and density of the copper wire.

Answer:
a). d=4.83m
b). d=3.876m
c). u=0.361
Explanation:
The blocks stops moving up the ramp when all the elastics Energy (Ek) in the spring has transfer to Energy gravity (Ep)
So using the law conservation of energy and in the motion
Energy Kinetic is the energy of the spring so 'K' is the force constant and xk is the distance the block compresses the spring and 'h' is the height for a ramp 60 angle so:
a).
Solving for 'd'
b).
Now the force of friction is acting so the Ep add the force
Get the factor to resolve d
c).
Finally if the distance of the rampo is knowing determinate the u coefficient of friction can be find
