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

Comets travel around the sun in elliptical orbits with large eccentricities. If a comet has speed 1.8×104 m/s when at a distance

natali 33 [55]

Answer:

9.4 x 10⁴ m/s

Explanation:

In circular or elliptical orbits , the angular momentum is conserved because torque is zero.

mr₁v₁ = mr₂v₂

2.2 x 10¹¹ x 1.8 x 10⁴ = 4.2 x 10¹⁰ v₂

v₂ = 9.42 x 10⁴ m/s.

= 9.4 x 10⁴ m/s
