Consider two transformers. Transformer A has 300 turns on its primary and 500 turns on its secondary. Transformer B has 250 turn
rusak2 [61]

Answer:

Secondary voltage on second transformer is 200 volt.

Explanation:

It is given two transformer

Let us consider first transformer.

Number of turns in primary N_p=300

Numb er of turns in secondary N_s=500

Now consider second transformer

Number of turns in primary N_p=250

Number of turns in secondary N_s=1000

Now it is given that same voltage of 50 volt is applied to primary of both the transformer.

For second transformer

\frac{N_p}{N_s}=\frac{V_p}{V_s}

\frac{250}{1000}=\frac{50}{V_s}

V_s=200volt

So secondary voltage on second transformer is 200 volt

4. An aluminium bar weighs 17 kg in air. How much force is required
kkurt [141]

Explanation:

1ml = 2.7g

Xml = 1.5g

Divide 1.5 by 2.7 to find X.

Obviously, since 1.5 is less than 2.7, you know the answer will be less than 1.

(it’s .5555555555)

In the attached position versus time graph what is the magnitude of average velocity for the entire 19 seconds of the motion. An
evablogger [386]

According to the plot, the positions at time <em>t</em> = 0 s and <em>t</em> = 19 s are -1 m and -2 m, respectively. So the average velocity for the 19-s interval is

v_{\rm ave} = \dfrac{-2\,\mathrm m - (-1\,\mathrm m)}{19\,\mathrm s} = -\dfrac1{19}\dfrac{\rm m}{\rm s}\approx \boxed{-0.05\dfrac{\rm m}{\rm s}}
