On the surface of the Earth, the escape velocity is about 11.2 kilometers per second 06.96 mi/s), which is approximately 34 times the speedof sound(Mach34) andseveral timesthemuzzlevelocity ofarifle bullet (up to 1.7 km/s). However, at 9,000 km altitude in "space", it is slightly less than 7.1 km/s. In physics,escapevelocityisthespeedatwhichthe kinetic energy plus the gravitational potential energy of an object is zero.
440.11 ÷ 21.98 × 5.14 – 72.9 = √?
‘A’ alone can complete a work in 12 days. ‘B’ alone can complete the same work in 24 days. If ‘A’ and ‘B’ work together for 4 days, then...
Solve the given equation for ?. Find the approximate value.
[(49.88% of 320.11) × (34.85% of 460.24)] ÷ √783.94 = ?
189.23 + 18.11² + ?³ = √841.76 * 28.94
24.99% of 1619.78 + (1259.84 ÷ 12.24) = ? × 16.98
? = 19.89% of (29.89 × 12.44) + 9.96 × 12.022
24.01 X 24.99 - ?% of 599.96 = 14.92 X 8.12
583.9 + 1519.98 - 445.21 = 1150.011 + ?
33.33% of 110.99 = 19.98% × 244.97 - √?
30.22% of (79.9 x 6.01) + 69.97 =?
