Answer:
Explanation:
In order to calculate the change of any quantity you must substract the initial value of that quantity from the final value of the same quantity.
The concept of momentum is defined as,
Momentum = mass×velocity
So we calculate the change of momentum as,
Momentum change = final momentum - initial momentum
= mv - mu =m(v-u)
Where v = final velocity
u = initial velocity
m = mass of the object
So to calculate the momentum change of the car,
Change in momentum of the car = 1000×(8-1) = 1000×7 = 7000 Ns
Answer:
A(n) <u>living wage</u> is the idea that people should be able to purchase the essentials of life by working a forty-hour workweek. Many local municipalities have as a result set higher minimum wages than the federally mandated minimum wage to accomplish this goal.
Explanation:
Living wage is the idea given to reduce poverty specially in cities with higher costs. It's based on the fact that one who works forty hours per week, he or she should be able to afford the basic needs of life that includes the water, food and shelter. Research has shown that the implementation of this concept has played the role in reducing poverty and enhancing the quality of life of workers. Countries like New-Zealand and united kingdom has supported this concept.
Answer: 1 : an observable fact or event. 2a : an object or aspect known through the senses rather than by thought or intuition. b : a fact or event of scientific interest susceptible of scientific description and explanation. More from Merriam-Webster on phenomenon.

<h3>What is a lens?</h3>
An optical device known as a lens uses refraction to focus or disperse a light beam. A compound lens is made up of multiple simple lenses (elements), typically aligned along a common axis, as opposed to a simple lens, which is one solid piece of transparent material. Glass or plastic are used to make lenses, which are then polished or molded into the required shape. In contrast to a prism, which just refracts light without focusing it, a lens can focus light to create an image. In addition to focusing visible light, lenses can also be used to disperse various types of waves and radiation, such as explosive, microwave, electron, and acoustic waves.

Answer:
9.5 m/s
Explanation:
Distance, S = 150m
Acceleration, a = 0.3 m/s^2
Initial velocity, u = 0 m/s
Final velocity, v
Use kinematics equation
v^2 - u^2 = 2aS
v^2 - 0 = 2*0.3*150 = 90
v = sqrt(90) = 9.49 m/s
