Which places did Kepler plan to see within six months of his stay on Earth |
|
Answer» Answer: This article is about the space telescope. For the style of refracting telescope invented by Johannes KEPLER, see Keplerian telescope. The Kepler space telescope is a retired space telescope launched by NASA to discover Earth-size planets orbiting other stars.[5][6] Named after astronomer Johannes Kepler,[7] the spacecraft was launched on March 7, 2009,[8] into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki. After nine years of operation, the telescope's reaction control system fuel was depleted, and NASA ANNOUNCED its retirement on OCTOBER 30, 2018.[9][10] Designed to survey a portion of Earth's region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and estimate how many of the billions of stars in the Milky Way have such planets,[5][11][12] Kepler's sole scientific instrument is a photometer that continually monitored the brightness of approximately 150,000 main sequence stars in a fixed field of VIEW.[13] These data are transmitted to Earth, then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star. Only planets whose orbits are seen edge-on from Earth can be detected. During its over nine and a half years of service, Kepler observed 530,506 stars and detected 2,662 planets.[14] HOPE this answer helps you |

3. If 2x+y=5 and y-1=0 then the value of x is (a) 4(b) 2 (c) 5 (d) 0 |
Answer» AnswEr :
⠀ Explanation :We are given with the two equation, that is,
We have to FIND out the value of x. Now, As we are given with two equation, first we will find the value of y, after that we will find the value of x. ⠀ → y - 1 = 0 → y = 1 ⠀ Substituting the value of y in equation (1) : → 2x + y = 5 → 2x + 1 = 5 → 2x = 5 - 1 → 2x = 4 → x = 4/2 → x = 2 ⠀ Hence, the value of x is 2. So, OPTION (b) 2 is correct. ⠀ ⠀⠀⠀⠀⠀⠀Verification :==> 2x + y = 5 ==> 2 × 2 + 1 = 5 ==> 4 + 1 = 5 ==> 5 = 5 Clearly, LHS = RHS. Here both the conditions SATISFY, so our answer is correct Hence Verified ! |

"The graph of the equation y=mx+c does not pass through origin." Justify the statement |
|
Answer» y = MX + c is the intercepting form of line of EQUATION, where c is CONSTANT at y-axis ( 0, c), m is the slope of the equation, It is only passing through the origin when we PUT (0, 0) then satisfy the equation for this point. e.g LHS = y =0, RHS = mx + c = m× 0 + c, LHS ≠ RHS, So, this line not passing through the origin. |

Find the coefficient of x4 in the expansion of (1 + x + x2 + x3)11 |
|
Answer» Answer: x 4 can be achieved in the following ways: x 4 .1 n−4 .(x ) .(x ) 0
Hence, COEFFICIENT will be n C 4 . x 2 .1 n−3 .(x 2 ) 1 .(x 3 ) 0
Hence, coefficient will be 3 n C 3 . x 1 .1 n−2 .(x 2 ) 0 .(x 3 ) 1
Hence, coefficient will be 2 n C 2 . x 0 .1 n−2 .(x 2 ) 2 .(x 3 ) 0
Hence, coefficient will be n C 2 . Hence, the required coefficient will be n C 4 +3 n C 3 +3 n C 2
= n C 4 +3( n C 3 + n C 2 ). = n C 4 +3( n+1 C 3 ). = n C 4 + n C 2 + n C 1 . n C 2 Step-by-step explanation: |

Find the mean propotional between √3 and √7 |
|
Answer» Answer: Two variables are in direct proportion if the ratio of the values of these two variables is constant. ⇒ If two variables x and y are in direct proportion, then xy=k, where k is a constant. An example is distance and time, where speed is constant. The ratio of distance and time =distancetime= speed, which is constant. Two variables are said to be proportional if there is a constant ratio between them, as in direct proportion. Three numbers are said to be proportional is the product of the first and third numbers is equal to the square of the second number. The numbers 10,20 and 40 are proportional because 10×40=202. The third proportional of two numbers a and b is a number C, such that ab=bc ⇒c=b2a. The fourth proportional of numbers a,b and c is a number d, such that ab=cd. ⇒d=bca. Two variables are in inverse proportion if the product of the values of these two variables is constant. ⇒ If two variables x and y are in inverse proportion, then xy=c, where c is a constant. An example is speed and time, where distance is constant. The product of speed and time = speed × time = distance, which is constant. |
