SSC CHSL 2020 ALL SHIFT VOCAB PART 2

For the reversible reaction N_(2) (g) +3H_(2) (g) hArr 2NH_(3) (g) + " Heat" The equilibrium shifts in forward direction

Let alpha and beta be the roots of x^(2)+x+1=0 , then the equation whose roots are alpha^(2020) and beta^(2020) is

If 2^(2020)+2021 is divided by 9, then the remainder obtained is

In a factory, workers work in three shifts, say shift 1, shift 2 and shift 3 and they get wages in the ratio 3:4:8 depending on the shift 1, 2 and 3 respectively. Number of workers in the shifts are in the ratio 3:2:5 . If the total number of workers working is 1500 and wages per worker in shift 1 is Rs. 300, then the mean wage of a worker is

In the expansion of (ax+b)^(2020) , if the coefficient of x^(2) and x^(3) are equal, then the value of (9)/(100)((b)/(a)) is equal to

For the reaction H_(2)(g)+I_(2)(g) hArr 2HI(g) , the equilibrium can be shifted in favour of product by

When the origin is shifted to a suitable point, the equation 2x^2+y^2-4x+4y=0 transformed as 2x^2+y^2-8x +8y+ 18=0 . The point to which origin was shifted is

The equilibrium, BaCO_3(s) hArr Ba0(s) + CO_2(g) will shift in left hand direction by

Given below is the diagram of bacteriophage. In which one of the options all the four parts A,B,C and D are correct?
