आपल्या घरातील अडागळीत टाकलेली वस्तू किंवा विकायाला काढलेली वस्तू जर तुमच्याशी बोलू लागली तर ती काय बोलेल याची कल्पना करून लिहा​

Explanation:

Light from torch, headlights of cars, etc. appears to travel in a straight line. Light from a projector travels in a straight line in the form of light rays towards the screen. Light emitted from a laser pointer appears to travel in a straight line.

Answer:

x and y =45, z= 90

Step-by-step explanation:

as z is the angle btw the diagonals and we know that the diognals of square intersects each other at 90 degree. so, z=90

and x and y are the angles opposite of the isoscles triangle so they are 45 degree each.

In a reaction A+B → products, the rate of reaction is doubled when the concentration of A is doubled and B is kept constant and the rate of the reaction is increased by 8 times when the concentrations of both A and B are doubled, thus overall order of the reaction is:

Medium

Solution

Correct option is C)

The expression for the rate of the reaction is

r=k[A] n[B] m −(1)

When the concentration of A is doubled and the concentration of B remains same, the rate expression becomes

2r=k[2A]n[B] m −(2)

When the concentration of both A and B is doubled, the rate expression becomes 8r=k[2A]

n [2B] m −(3)

Divide equation (2) with equation (1) to obtain n=1

Divide equation (3) with equation (1) to obtain n+m=3

Hence, m=2

The overall order of the reaction is =1+2=3.

Explanation:

One thing that you have to remember is that when you are finding the domain of a polynomial, it is all real number. it runs from

(

−

∞

,

∞

)

For finding the range, in a quadratic formula, you have to find when the finction has it's vertex. That is the place that the max or min happens and then you can find the range from there.

in this situaltion we found that the vertex is at the the origin at (0,0)

therefore the range is (0,
