At a time t= 3.40s , a point on the rim of a wheel with a radius of 0.210m has a tangential speed of 53.0m/s as the wheel slows down with a tangential acceleration of constant magnitude 11.0m/s2 .

part a

calculate the wheel's constant angular acceleration.

part b

calculate the angular velocity at t = 3.40s .

part c

calculate the angular velocity at t=0.

part d

through what angle did the wheel turn between t=0 and t = 3.40s ?

part e

prior to the wheel coming to rest, at what time will the radial acceleration at a point on the rim equal g = 9.81m/s2 ?

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

i think the answer would be reserve.

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
