Why does an empty plastic bottle forcefully pushed into the water come up when it is released? Due to up thrust exerted by the bottle on water. Due to up thrust exerted by the water on plastic bottle. Due to pressure of water on plastic bottle. Due to pressure of plastic bottle on water.

(ii) because of the upthrust that the water exerts on the plastic bottle

Which is the dependent variable in the experiment where solubility of sugar is measured at different temperatures?

Solubility of sugar (i.e., the amount of sugar that can dissolve in a given amount of water) is the dependent variable — it changes with temperature. (Temperature is the independent variable, and the amount of water is the controlled variable.)

Arrange the following animals in the order of evolution. Cockroach, earthworm, fish, frog.

(earthworm → cockroach → fish → frog)

What is high sistolic pressure?

Systolic blood pressure is the highest pressure on the arterial walls when the heart's ventricles contract and blood is pushed into the arteries. In adults its normal value is about 120 mm Hg. If this value repeatedly rises above 140 mm Hg it is called high systolic blood pressure (hypertension). [Note: The Nepali question asks 'What is systolic blood pressure?' while the English asks 'high systolic pressure'. Therefore both are included above.]

If the power of lens is + 4 D, find its focal length.

Power P = 1/f (f in metres) 4 = 1/f f = 1/4 = 0.25 metre = 25 cm Answer: the focal length is 0.25 metre (25 cm). The power is positive, so this is a convex (converging) lens.

Draw a ray diagram of the image formed by the lens having focal length 2.5 cm and the object is kept at 6 cm away.

What is meant by 'the frequency of alternating current in our country is 50 Hz'?

This means — the alternating current completes 50 complete cycles in one second. Because the current's direction reverses twice in one cycle, the direction of the current changes 100 times in one second. That is, one cycle takes 1/50 = 0.02 seconds to complete.

In the given graph of future of the universe, what type of universe does 'B' represent? [Graph: time since the Big Bang on the X-axis, the radius of the universe on the Y-axis. Curve A goes on rising; curve B rises and levels off; curve C rises and then falls again.]

'B' represents a flat universe (Flat universe). In such a universe the expansion never completely stops, but gravity continually slows it down — therefore the curve rises and then progressively levels off. This is the case when the density of the universe is exactly equal to the critical density. (For comparison: curve A represents an open universe — expanding forever; curve C represents a closed universe — expanding and then contracting again, i.e. showing the 'Big Crunch'.)

Write balanced chemical equation when dust formed by burning magnesium ribbon is added to water.

2Mg + O₂ → 2MgO MgO + H₂O → Mg(OH)₂
