The work done by a centripetal force on an object moving in a circular path is:
Centripetal force acts perpendicular to the motion of the object, resulting in no work being done as there is no displacement in the direction of the force.
(7/4×18/21)+ (51/7× 28/17) + (25/2 × 48/10) =?
0.3 × 0.2 + 0.4 × 0.3 + ? = 413.18
(64/25)? × (125/512)?-1 = 5/8
5.5 × 3.2 × 2.3 = ?
4.7 × 3.5 + 4.2 × 4.5 = 22.5 × 3.5 - ?
5760 ÷ 45 × 15 = ?
{(700 ÷ 20) × 40} – 30 × 18 = ?% of 1000
36 x 3.6 ÷ 0.5 ÷ ? = 64
432 ÷ ? × 2552 ÷ 44 = 2088
(3/7 )Of 3360 ÷ 240 + 30 = (?)²
