A 1500kg car accelerates from 50km/h to 75km/h. How much work was done?

Work done, W = 181238.4 J

Explanation:

We have,

Mass of a car, m = 1500 kg

Initial speed, u = 50 km/h = 13.88 m/s

Final speed, v = 75 km/h = 20.84 m/s

Let W is the work done. It is equal to the change in kinetic energy of the car. So,

So, 181238.4 J of work was done by the car.

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

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
