Answer:
The correct answer is B. Both of eyes see the images a little differently, because of the horizontal separation of the two eyes. This difference is proportional to the relative depth. Brain measures these differences and we obtain a stereo image of the objects that we see.

Like charges will repel, unlike charges. The same is true for the magnetic fields. When you take two of the same type of magnets, you can see if you can find out which poles are similar (both south or both north). A separation<span> between magnets affects the force each exerts on the other isn't simply due to the fact that in the use of the magnetic pole model, poles always come in pairs. It would be much simpler if it would be possible to have a single magnetic pole on one magnet interacting with a single pole on the other, but this doesn't happen.

Answer:
1.4 kg
Explanation:
m1 = 0.7 kg
Let the mass of second block is m.
x1 = x
x2 = 3x
According to the Hooke's law
F1 = - kx1
m1 g = - k x
0.7 g = - k x ..... (1)
When both the blocks are placed
(m1 + m2) g = - k x2
(0.7 + m) g = - 3 k x .... (2)
Divide equation (2) by equation (1), we get
(0.7 + m) / 0.7 = 3
0.7 + m = 2.1
m = 2.1 - 0.7
m = 1.4 kg
thus, the mass of second block is 1.4 kg.
