The given question is incomplete. The complete question is as follows.

Brad tries out a weight-loss plan that involves repeatedly lifting a 52.0-kg barbell from the floor over his head to a height of 2.3 m. If he is able to complete three such lifts per minute, how long will it take for him to lose 0.50 kg of fat? "Burning" 1 g of fat supplies 39 kJ to the body; of this, 10% can be used by the muscles to lift the barbell. (Ignore the fat "burned" while he lowers the barbell to the floor.)

Explanation:

For the given situation,

Energy given by his "fat" = work done by the gravity

$0.5 \times 30 \times 10^{3} \times 10^{3} \times \frac{10}{100} = \frac{2.3 \times 52 \times 9.8 \times 3}{60} \times t$

$15 \times 10^{5} = 58.604 t$

t = 25595.52 seconds

As there are 3600 seconds present in 1 hour. So, convert 25595.52 seconds into hours as follows.

$\frac{25595.52 seconds}{3600 sec/hr}$

= 7.10 hours

Thus, we can conclude that it will take 7.10 hours from Brad to lose 0.50 kg of fat.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
