A spaceman in training is rotated in a seat at the end of a horizontal arm of length 5 m. If he can with stand acceleration upto 9 g, then what is the maximum number of revolution per second permissible? (Take, g =`10ms^(-2)`)

If a space man is rotated at the end of a long beam of length 5 m and the acceleration of 9 g, then the number of revolution performed will be

If a speed man is rotated at the end of a long beam of length 5m and the acceleration of 9g, then the number of revolution performed will be ( g=10 m//s^(2))

An astronaout is rotating in a rotor of radius 4m. If he can withstand upto acc. Of 10g, then what is the maximum number of permissible revolutions? (g=10m//s^(2))

A string 1 m long can just support a weight of 16 kg. Amass of 1 kg is attached to one of its ends. The body is revolved in a horizontal circle about the other fixed end of the string. Find the greatest number of revolutions made by the mass per second ? (Take g = 10 ms^(-2) )

A string 1 m long can just support a weight of 16 kg. A mass of 1 kg is attached to one of its ends. The body is revolved in a horizontal circle about the other fixed end of the stringy Find the greatest number of revolutions made by the mass per seconds ? (Take g=10 ms^(-2) ) The maximum tension the string can withstand = weight of 16 kg.

A ball of 0.03 m diameter and 0.3 kg in weight is attached to the end of a thin string of 0.46 m length. If it is rotate uniformly in a horizontal circle at the rate of 15 revolutions per second, what is the tension in the string? Take pi^2 = 9.87 ).
