Explanation:

(i)The lesser the resistivity of a CONDUCTOR ,the more it allows electric current to pass through it .

Insulators have the maximum resistivity and conductors have the minimum resistivity.

In the given question the best conductor will be the one having minimum resistivity.

So, material A is the best conductor , SINCE it has minimum resistivity.

AND,

Material B the best INSULATOR since it has maximum resistivity.

(ii)Resistivity of a conductor does not depend on its length .

If the length of the conductor is increased twice ,the resistivity will remain constant.

It will not change.

Hence, after doubling the length of the given wire, resistivity will be P only.

Snell's law, in OPTICS, a relationship between the path taken by a ray of LIGHT in CROSSING the boundary or surface of SEPARATION between two contacting substances and the refractive index of each. This law was discovered in 1621 by the Dutch astronomer and mathematician Willebrord Snell (also called Snellius)

Thus we need the MAS in TONS that is M / 1000

Step-by-step explanation:

(1) Now 1st we will calculate this:

Ao ^flap =  81 X 8 π σo^ flap x ho^ flap x ρ(air) x V  x r^2 x L^3

σo^ flap = 150 x 10^6

(2) Then we will calculate:

Ao^edge and σo^edge=150*10^6

(3) The third step:

M = 2 x (Ao^flap + Ao^edge) x 86 x 2700

Finally

M / 1000

Thus we need the mas in tons that is M / 1000

Answer:

When a CHARGE of equal magnitude is PLACED on both the conducting spheres, then only the repulsive force between them SHALL be maximum. ... Therefore, since the distance is fixed, equal CHARGES will have maximum product therefore the charge q be equally distributed as q / 2 on each of conducting sphere.

Triangle ABC is a RIGHT triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the PYTHAGOREAN theorem,

AB=202−162=400−256=144=12

Since triangle DEF is SIMILAR to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,

sinF=oppositesidehypotenuse=ABAC=1220=35

Therefore, sinF=35.

The final answer is 35 or 0.6.

SORRY DON'T KNOW ANSWER

Explanation:

v=u+at

20=0+10a

a=2

s=0+1/2(2)(10)²

s=100m OK FRIEND this is URS answer

Answer:

s=14.7 m

Explanation:

We can use the formula,

[s (nth second) = u + 1/2 a (2 N - 1)],

(Where u = initial velocity

a = acceleration and s= displacement)

which can easily be derived by subtracting the displacement in (n - 1) SECONDS from the total displacement in 'n' seconds. (Kinematical  equation for displacement in 'n' seconds is s= un + 1/2 a n²)

Total TIME taken for stone to fall,

(Here acceleration = G = 9.8 m/s²)

19.6 = (0)t + 1/2(g)n²

=> n² = (19.6 x 2)/ 9.8

=> n² = 4

=> n = 2 seconds (total time taken for stone to fall)

Therefore, displacement in last, that is the 2nd second,

S = (0) + 1/2(g) (2(2) - 1)

(Here u = 0, n = 2 and acceleration = g)

=> s = 1/2 x 9.8 x 3

=> s = 14.7 m <-- Ans.

Answer:

At the end of 2 min 20 sec.,

• Distance covered is 2200m

• Displacement is 200m.

Explanation:

Given:

Diameter of circular track = 200m

Time taken for 1 ROUND = 40 sec.

To find :

The distance covered and displacement

Solution :

Diameter = 200m

Radius =

200 / 2

100m

Therefore,

Radius = 100m

Time taken for 1 round = 40 sec.

First convert minute into seconds

So,

2min. 20 sec. = 140 seconds

Number of round = 140 / 40

3.5 means 3 and half round

Therefore,

Number of round = 3.5

Circumference of circle = 2 π r

Distance covered = 3.5 × Circumference of circular track

➙ 3.5 × 2 π r

➙ 3.5 × 2 × 22 / 7 × 100

➙ 2200m

Therefore,

At the end of 2 min 20 sec.,

Distance covered is 2200m

Displacement is 200m.

EXPLANATION:

DISTANCE = 50 m

displacement=(150)^2

ANSWER:

USE the FORMULA f=g(m1×m2)/r^2
