Answer:

N_2=30turns

So option (b) will be correct option

Explanation:

We have given that there is a step up transformer in which number of turns in primary coil is 15

That is, N_1=15

Primary voltage V_1=80volt, and secondary voltage V_2=160volt

We have to find the number of turns in the secondary \

We know that for the transformer

\frac{N_1}{N_2}=\frac{V_1}{V_2}

\frac{15}{N_2}=\frac{80}{160}

N_2=30turns

So option (b) will be correct option

Let, 1st force = a

2nd force = b

A.T.Q,

a+b = 10

a-b = 6

Calculate for a & b, you'll get a=8 & b= 2

After increasing by 3, it'll be a = 8+3 = 11 & b=2+3 = 5

Resultant force at 90 degree angle = 11+5 = 16 Newtons

State and explain the principle of superposition of electrostatic force​
ella [17]

Answer:

The principle of superposition states that when a number of charges are interacting, the net electrostatic force a given charge is the vector sum of the forces exerted on it due to all other charges. The force between two charges is not affected by the presence of other charges.

Distance of fall from rest,
without air resistance              =  (1/2) (gravity) (time)²

                                             = (1/2) (9.8 m/s²) (95 sec)²

                                             =  (4.9 m/s²) (9,025 sec²)

                                             =        44,222.5 meters  .

The depth of the mine shaft is five times the height of Mt. Everest !
