Question
The time period of a pendulum when taken to the Moon
would:Solution
Since the pendulum rate will increase with an increase in gravity, and local gravity varies with latitude and elevation on Earth, pendulum clocks must be readjusted to keep time after a move. For example, a pendulum clock moved from sea level to 4000 feet will lose 16 seconds per day.
I. y² + y – 56 = 0
II. 2x² + 11 x – 40 = 0
Quantity I: The cash price of a notebook is Rs. 100 but is can also be purchased on 11 monthly equal instalments of Rs. 10 each. Find rate of S.I.?
...I:Â x2Â - 33x + 242 = 0
II:Â y2Â - 4y - 77 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 19x² - 88x + 100 = 0
Equation 2: 17y² - 79y + 90...
I. 27x² + 120x + 77 = 0
II. 56y² + 117y + 36 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 13x² - 60x + 47 = 0
Equation 2: 17y² - 80y + 63 = 0
I. 4x² -  15x + 9 = 0
II. 20y² -  23y + 6 = 0
I. x2 – 36 = 0
II. y2 - 7y + 6 = 0
I. x2 – 13x + 40 = 0
II. 2y2 – 15y + 13 = 0Â
I. 66x² - 49x + 9 = 0
II. 46y² - 37y - 30 = 0
