if anyone knows then plzz send solution...
thank you​

Answer 1

Answer:

Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it's a vector quantity.

Values of g in SI: 9.806 ms-2

SI Unit: ms-2

Formula: g = GM/r2

Answer 2

Answer:

a = -11

a = -11b = 5

Step-by-step explanation:

2x² + xy -3y² + x + ay - 10 = (2x+3y+b)(x-y-2)

RHS = (2x+3y+b)(x-y-2) = (2x)(x) + (2x)(-y) + (2x)(-2) + (3y)(-y) + 3y(x) +(3y)(-2) + (b)(x) + (b)(-y) + (b)(-2)

= 2x² - 2xy - 4x -3y² +3xy - 6y +bx - by - 2b

= 2x² - 3y² + (-2xy+3xy) + (-4x + bx ) + (-6y -by) -2b

= 2x² - 3y² + xy + x (b-4) -y (6+b) -2b

given that LHS = RHS

so

(2x² + xy -3y²) + x + ay - 10 = (2x² + xy - 3y²) + x (b-4) -y (6+b) -2b

=> x + ay - 10 = x(b-4) + y (-6-b) -2b

comparing both side

we get

coefficient of x on both side,

1 = b - 4

=> b = 1+4 = 5

coefficient of y,

a = (-6-b) = (-6-5)

=> a = -11
