Using, w = √ (k/m), we get: w = √ (1/2)s^-1.
Maximum velocity = Aw.
2 = A/√2
∴ A = 2√2 m.

w = √2/2 = 1. Time period of SHM = 2π/w = 2π s.
Speed of the block will be maximum at the mean position.
Time to reach mean position from extreme position = T/4
= 2π/4 = π/2 =1.57s.
Time for the small ball to fall down = √(2h/g) = √(4/9.8) = 0.63s.
∴ Time when it should be released
= 1.57 – 0.63 s
= 0.94s.

Time period of seconds pendulum = 2s.
∴ 2 = 2π √(L/9.8)
OR L = 1m.

The temperature at which a real gas obeys Boyle’s law and other ideal gas law at a certain range of pressure is called Boyle temperature or Boyle point. It is unique for every gas and depends upon its nature.

The ideal gas equation is given as (P – an²/V²)(V – nb) = nRT. So by considering the equation, we can understand that the units of the volume are equal to the units of a number of moles X be so the units of b. So b’s units = volume / number of moles so it is L/mol.

Compressibility factor Z = PV/nRT; Z = 50 atm x (500/1000) ml / 2 x 0.082 x 300 k = 25/6×8.2 = 0.5081. That means Z < 1, so this is a negative deviation from ideal gas behaviour. So the gas is more compressible than expected.

Rice doesn’t show vernalisation. Other crops such as Wheat, Barley and rye which are have two varieties: spring and winter require cold treatment to stimulate photoperiodic response of plants.

Polycarpic plants are plants that set seeds numerous times before senescence. Apple is a polycarpic plant. Sugarbeet, Cabbage & Carrots are some of the common biennials. Biennials are plants that take 2 seasons to complete their lifecycle.

The F₁ headpiece that is present in the Complex V is a peripheral membrane protein complex and contains the site for synthesis of ATP from ADP and inorganic phosphate.

Glucose is the favoured substrate for respiration because glucose is a carbohydrate and is readily available in the cells through the food that cell intakes. It also releases a large amount of energy on its oxidation.
