Answer:
The radius of curvature is 979 meter
Explanation:
We have given velocity of the canon ball v = 98 m/sec
Acceleration due to gravity 
We know that at highest point of trajectory angular acceleration is equal to acceleration due to gravity
Acceleration due to gravity is given by
, here v is velocity and r is radius of curvature
So 
r = 979 meter
So the radius of curvature is 979 meter
Biometric sensors are used to collect measurable biological characteristics from a human being, which can then be used in conjunction with biometric recognition algorithms to perform automated person identification.
Answer:
b. diagnoses and corrects errors in an operational system
Explanation:
Corrective maintenance is one that is performed with the purpose of repairing faults or defects that occur in equipment and machinery. As such, it is the most basic way of providing maintenance, as it simply involves repairing what has broken down. In this sense, corrective maintenance is a process that basically consists of locating and correcting faults or damages that are preventing the machine from performing its function in a normal way.
