What is the velocity of an object that has a mass of 2.5 kilogram and a momentum of 1,000 kg·m/sec?

Answers

Answer 1

Answer: P=MV. P=1000 M=2.5 V=?.
1000=2.5 x V
Divide both sides by 2.5
400=V
The velocity is 400

What is the equation for calculating a machine's efficiency?I searched all over my textbook and couldn't find it, so I decided to post my question here.

Answers

Efficiency of a machine is defined as the ratio of work performed on it to work performed by it.

What is the fundamental meaning of efficiency?

Efficiency is the capacity to achieve something or get a desired outcome without wasting resources, time, money, energy, or effort. In a broader sense, it is the capacity to carry out tasks effectively and efficiently.
Effectiveness and efficiency are frequently misunderstood. Efficiency is often a quantifiablenotion that is based on the ratio of total useful input to total useful output.
When a machine uses the majority of the power provided to it for its load and just a small portion for waste, it is said to be highly efficient.

Efficiency = Output energy/ Input energy

The percentage value of efficiency of a machine is calculated as:

Efficiency = (Output energy/ Input energy) X 100%

Efficiency is usually defined as how much useful work output do you get for each unit of work input.

Efficiency = work output/work input

Work input = effort force * effort distance
Work output = load force * load distance

Which of the following best defines "medium of exchange"?A. something with a fixed value that we use for exchange
B. a way to determine what is the best deal
C. the average value exchange of a single good or service
D. a monetary rate that stays constant

Answers

Answer:

The best sentence to define "medium of exchange" is:

A. something with a fixed value that we use for exchange

Explanation:

The medium of exchange is the concept to name the tool we use as a medium to exchange different products with the intention o reaching an objective agreement. To achieve this, the medium of exchange has to have a general value and even when its value can increase or decrease based on the economical conditions of the environment it is adaptative and will always behave in a proportional ratio.

I find the first option best.

B. even if something is a best deal - we might not be able to get it, so exchange might not even take place.
C. this would not be a "medium"
D. - well, there isn't such a rate, is there?

So, answer A is really the best - and I think it's also a good definiton
