water is projected from two rubber pipes at the same speed from one at angle of 30 and from the other at 60 why are the ranges equal
The range is 46.
no, 25.4 mm Direct Conversion Formula 30 mm* 1 in 25.4 mm = 1.181102362 in
first you need add them all then divide the of the same for example x (3) + 2x = 60 x = 20 20 + 20 +20 = 60 2x 30 + 30 = 60 hope this help
Think of 900 square feet as a square that is 30 feet by 30 feet. 1 foot is the same as about 0.3 meters, so 30 feet is 0.3x30=9 meters. So a square that is 9 meters by 9 meters is 81 square meters.
3 students can be chosen from a class of 30 in (30 x 29 x 28) = 24,360 ways.But each group of the same 3 students will be chosen in six different ways.The number of different groups of 3 is 24,360/6 = 4,060 .
Without going into a large Calculus based proof, if two angles of projection are complementary (add to 90 degrees) then the ranges are the same. A 45 degree angle yields the greatest range, but 40 degrees and 50 degrees would yield the same range, so would 30 degrees and 60 degrees. Similarly, 0 degrees and 90 degrees would also have the same range (a range of zero, that is).
w2hen the angle of projection is larger than 45 degree the height attained will be more but the range is again less.in this case angle is 30 degree which is less than 45 degree and 60 degree angle is greater than angle of 45 degree which have less range and is equal to range of 30 degree .so ranges are equal.
body is projected with a velocity 3o m/s at an angle 30 degree with vertical find maximum height time of flight and range
because 30 and 60 makes 90
