Answer:

F = 0.64 N

Explanation:

We are given;

Spring constant constant; k = 1.28 N/m

Distance; x = 0.5 m

From Hooke's law, we know that F = kx.

Thus;

F = 1.28 × 0.5

F = 0.64 N

Thus, force it takes to pull the spring back = 0.64 N

B.A certain piece of copper wire is determined to have a mass of 2.00 g per meter.
masha68 [24]

Answer:

14cm

Explanation:

Mass per gram of the piece of wire;

         2g of the wire is found in 1m

 Since

       100cm  = 1m;

 

So;

       100cm of the wire contains 2g of the wire

To provide 0.28g

 Since;

        2g of wire is made up of 100cm

      0.28g of wire will be contained in \frac{100 x 0.28}{2}   = 14cm

14cm of the wire will contain 0.28g

4. What's the voltage drop if V, = 56 V, V2 = 35 V, and V3 = 3 V
Murrr4er [49]

Answer:

The correct option is A. 18 V

Therefore,

V_{1}=18\ V

Explanation:

Given:

Total Voltage,

V = 56 V,

Voltage drop

V_{2}=35\ V

V_{3}=3\ V

To Find:

V_{1}=? (Assumed ,as it is not given clearly in the question)

Solution:

So in series combination total Voltage is given as

V=V_{1}+V_{2}+V_{3}

Substituting the values we get

56=V_{1}+35+3\\\\V_{1}=56-38=18\ V

Therefore,

V_{1}=18\ V
