As, F is inversely proportional to square of distance between them
a) When it will be doubled the force will reduce 4 times
ie. 10/4 =2.5
b) i) F= k*1/d²
ii)  k=3² *2= 18
 Therefore F= 18/5² =18/25 =0.72

What is P versus NP, its supposed to be one of the hardest questions in the world
iogann1982 [59]

Answer:

P is the set of problems whose solution times are proportional to polynomials involving N's. ... NP (which stands for nondeterministic polynomial time) is the set of problems whose solutions can be verified in polynomial time. But as far as anyone can tell, many of those problems take exponential time to solve.

What coordinate do lines 2/3x+1/6y=2/3 and 4x+y=4 meet?
VMariaS [17]

Answer:

The coordinates of the lines when both lines meets at point is ( 0, 0 )

Step-by-step explanation:

Given as :

The two lines are

\frac{2}{3}x + \frac{1}{6}y = \frac{2}{3}

And 4 x + y = 4

The coordinate of the lines are obtained when the two lines intersect

Let the coordinate of intersection points are ( x , y )

Now , The first lines as

\frac{2}{3}x + \frac{1}{6}y = \frac{2}{3}

Or, Taking LCM we get ,

\frac{4x + y}{6} = \frac{2}{3}

Cross multiplication both sides

Or, 3 × ( 4 x + y ) = 2 × 6

Or,  3 × 4 x +  3 × y = 12

Or, 12 x + 3 y = 12          ...........A

Other line is 4 x + y = 4

i.e 3 × ( 4 x + y ) = 3 × 4

or, 12 x + 3 y = 12          .........B

Solving both the line equations

(12 x + 3 y ) - ( 12 x + 3 y ) = 12 - 12

I.e x = 0  and  y = 0

So coordinates are ( x , y )  =  ( 0 , 0 )

Hence The coordinates of the lines when both lines meets at point is ( 0, 0 ) Answer
