<span>Brass is an <u>alloy</u>. An alloy
is a mixture of elements to form a unique material. Brass is a mixture of copper
and zinc and the percentage of each element depends on the desired material. It
has a higher malleability than bronze or zinc. Meaning that it can be bend
easily into it desired form.</span>
Explanation:
Below is an attachment containing the solution.
Answer:
Resistance of the second wire is twice the first wire.
Explanation:
Let us first see the formula of resistance;
R = pxL/A
Here L is the lenght of the wire, A the area and p is the resistivity of wire.
As we are given that the length of second wire is double than that of the first wire, hence the resistance of second wire would be double.
Since we have two loop in second case, inducing double voltage but as resistance is doubled so the current would remain same according to ohms law
I = V/R

Answer:
The spring constant is 45.94 N/m.
Explanation:
Given that,
Length = 50 cm
Mass = 270 g
Stretching the spring = 24 cm
We need to calculate the spring constant
Using formula of energy
The change in potential energy equal to the change in kinetic energy.

Put the value into the formula



Hence, The spring constant is 45.94 N/m.
