Daily NEET MCQ- May 6, 2022 - Question 1

What is the time period of kinetic energy of a particle in SHM,if the time period of SHM is 4s?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 1

The kinetic energy of a particle in SHM is given by:
0.5mA2w2cos2(wt + a), where a is the phase constant.
cos2(wt + a) = (1 + cos2(wt+a))/2.
Therefore the time period of oscillation of kinetic energy is 4/2 = 2s.

Daily NEET MCQ- May 6, 2022 - Question 2

Consider a particle undergoing an SHM of amplitude A & angular frequency w. What is the magnitude of displacement from the mean position when kinetic energy is equal to the magnitude of potential energy?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 2

Let x = Asin(wt).
∴ Kinetic energy = 1/2 mA2w2cos2(wt)
potential energy = 1/2kA2sin2(wt).
According to given condition:
1/2mA2w2cos2(wt) = 1/2A2w2sin2(wt)
using, k = mw2, we get:
tan2(wt) = 1.
∴ wt = π/4.
∴ x = Asin(π/4) = A/√2.

Daily NEET MCQ- May 6, 2022 - Question 3

A particle is undergoing SHM. If its potential energy is given by: U = kx2. What will be the value of x for potential energy to be 1/3rd of kinetic energy? Assume k is force constant.

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 3

Let x = Asin(wt).
U = kA2sin2(wt)
K = 1/2mA2w2cos2(wt).
Given: U = 1/3K.
kA2sin2(wt) = (1/3)*(1/2)mA2w2cos2(wt),
and k = mw2.
∴ tan2(wt) = 1/6. Or tan(wt) = 1/√6.
∴ sin(wt) = 1/√7.
x = Asin(wt) = A/√7.

Daily NEET MCQ- May 6, 2022 - Question 4

A particle is in SHM. When displacement is ‘a‘ potential energy is 8J. When displacement is ‘a‘ potential energy is 18J. What will be the potential energy when displacement is ‘a+b’?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 4

1/2ka2 = 8 & 1/2kb2 = 18.
We have to find value of 1/2k(a + b) 2.
∴ 1/2k(a + b)2 = 8 + 18 + kab
= 26+(k*4*6/k)
= 26 + 24 = 50J.

Daily NEET MCQ- May 6, 2022 - Question 5

The purification method where solid substances change from solid to vapor state without passing through the liquid state is called as which of the following?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 5

In sublimation, the solid substance transforms directly to the vapor state without entering into the liquid state. This helps in separating sublimable compounds from non-sublimable ones. Whereas the other three, i.e. crystallization, distillation and differential extraction are used when a suitable solvent is involved. In other words, they deal with mainly liquids and not solids alone.

Daily NEET MCQ- May 6, 2022 - Question 6

What is the basis for the process of distillation?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 6

The process of distillation is based on the difference in the boiling points of the liquids. This is because, liquids having different boiling points vaporize at different temperatures. In this way, the vapors cooled can be collected separately from the liquid formed. Crystallization is used to separate volatile liquids from non-volatile liquids as well.

Daily NEET MCQ- May 6, 2022 - Question 7

Which of the following is the apparatus for differential extraction?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 7

A seperatory funnel is used in differential extraction. Differential extraction involves separating the immiscible organic compound from the aqueous solvent. The separating funnel aids in this process of separating immiscible liquids. It also helps in layer formation, with the denser solvent at the bottom and the other on top. This layer formation is important for the process, and thus, separatory funnel is chosen as the apparatus for differential extraction.

Daily NEET MCQ- May 6, 2022 - Question 8

Where do plants obtain most of their carbon and oxygen?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 8

Plants obtain most of their carbon and most of their oxygen from CO2 in the atmosphere. However, their remaining nutritional requirements are obtained from water and minerals in the soil.

Daily NEET MCQ- May 6, 2022 - Question 9

How do most minerals enter the root?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 9

Most minerals enter the root by active absorption into the cytoplasm of epidermal cells. This needs energy in the form of ATP. Some ions also move into the epidermal cells passively.

Daily NEET MCQ- May 6, 2022 - Question 10

Where does the unloading of mineral ions occur in the plants?

Detailed Solution for Daily NEET MCQ- May 6, 2022 - Question 10

Unloading of mineral ions which are required by the plants for growth and development occur at the fine vein endings through diffusion and active uptake by the plant cells.
