[v] = [a] ⇒ [a] = [M⁰L¹T^-1]

[v] = [bt]

[b] = \(\frac{[v]}{[t]}\)

[b] = \(\frac{[M^0LT^{-1}]}{[T]}\) ⇒ [M⁰LT^-2]

P = I/R

Where, P = Pay- back period, 

I = Investment or cost of project,

R = Return from investment

Given,

Cost of Project (I) Rs 1500000

Return from investment =(R) 600000

P = 1500000/600000 = 2.5 years

So, Pay-back period is 2yrs and 6 moths

(a) Let the present ages of P and Q be 3x and 4x respectively.
Then,

(4x + 4) – (3x + 4) = 5
⇒ 4x – 3x = 5
⇒ x = 5
 P’s present age
= 3 × 5 = 15 yrs.

Given:

Calculation:

According to the question,

Total number of Computer students

⇒ 150 + 125 + 130 + 150

⇒ 555

Total number of Statistics students

⇒ 150 + 220 + 170 + 125

⇒ 665

Difference in the number of computer and statistics students

⇒ 665 – 555

⇒ 110

∴ Difference in the number of computer and statistics students is 110.

Given:

Maximum number of student in DJ college 785

Calculation:

Total student in VP college is 720

⇒ Total student in DJ college is 785

⇒ Total student in KS college is 750

⇒ Total student in GB college is 680

∴ Maximum number of student is in DJ college.

1. The poet compares the state of her heart with a singing bird, an apple tree laden with fruits, a rainbow shell. She is happier than all of them because her love is coming to her. She wishes a stage to be prepared with silk and feathers. Squirrel fur should be hung. It should have paintings of birds and fruits. It should have peacock feathers. She has her birthday and her love is coming to her.

Answer is (4)

Speed of motion increased

Energy of molecules increase

a. 20 g of hydrogen (H₂): GMM = \(\frac{20}{2}\) = 10 Number of molecules = 10 × 6.022 × 10²³

Total number of atoms = 2 × 10 × 6.022 × 10²³ 

= 20 × 6.022 × 10²³

b. 88.75 g of chlorine 

Number of GMM = \(\frac{88.75}{71}\) = 1.25

Number of molecules = 1.25 × 6.022 × 10²³

Total number of atoms = 2 × 1.25 × 6.022 × 10²³ 

= 2.5 × 6.022 × 10²³

c. 4 g Calcium (Ca) 

Number of GMM = \(\frac{4}{40}\) = \(\frac{1}{10}\) = 0.1 

Number of molecules = 0.1 × 6.022 × 10²³

Total number of atoms = 1 × 0.1 × 6.022 × 10²³ 

= 0.1 × 6.022 × 10²³ 

d. 7.75 g Phosphorus Number of GMM = \(\frac{7.75}{31}\) = \(\frac{1}{4}\) = 0.25 

Number of molecules = 0.25 × 6.022 × 10²³

a. GMM of NO₂ 

= 14 + 2 × 16 = 46 g 

b. Number of mole = \(\frac{368}{46}\) = 8

c. Number of molecules = Number of moles × NA = 8 × 6.022 × 10²³

d. Number of atoms = Number of atoms in one molecule × Number of molecules = 3 × 8 × 6.022 × 10²³ = 24 × 6.022 × 10²³

e. Volume in STP = Number of moles × 22.4 L = 8 × 22.4 L = 179.2 L

The space needed for a substance to occupy is its volume. The volume of solids and liquids are definite. But the volume of a gas is the volume of its container in which it is present.

The average Kinetic energy of all the molecules in a substance is its temperature

The force exerted at unit area is pressure, Therefore, force at unit area/ pressure

= \(\frac{Force\,exerted\,at\,the\,surface}{Area\,of\,the\,surface}\)

Relatively more dust particles are found in the industrial cities and the dry air of arid territories.

The correct answer is 1894.

• The Right to Fair Compensation and Transparency in the Land Acquisition, Rehabilitation and Resettlement Act, 2013, replaced the Land Acquisition Act of 1894.

• According to this law:
  • All acquisitions require rehabilitation and resettlement to be provided to the people affected by the acquisition.
  • Compensation for the owners of the acquired land shall be four times the market value in the case of rural areas and twice in the case of urban areas.

The acidity and alkalinity of your blood are measured using the pH scale. The pH scale ranges from 0 (very acidic) to 14 (very alkaline). Blood is usually between 7.35 to 7.45.
