Answer:
You didn't add the choices but I'll add some ideas anyway.
Explanation:
Let's start with perhaps the most obvious impact of science on the economy: technology. Scientific discoveries lead to the development of new technologies, which then enter into international markets as highly desirable products.
While humans have always traded technologies, the relationship between technological development and economic growth really dates back to the Industrial Revolution of the 18th and 19th centuries. This was the first time that products were being produced on a massive scale, and it was new technologies in steam engines that allowed this to happen.
As people produced more goods, they developed more complex networks of economic exchange across the world. In fact, our modern ideas about free-market economies and capitalism actually date back to this same time period.
Our modern technologies and our modern economies developed simultaneously. We couldn't have one without the other. Today the United States' economy is very largely dependent on the exportation of communications and digital technologies. Its place in the global economy is not defined by its agriculture or raw products, but by its technologies.
Answer: Technician B
Explanation: A valve overlap occurs when both the exhaust valve and the inlet valve are open at the same time.
It is also seen as the number of degrees at which both the inlet and exhaust valves are open.
Valve overlap helps in boosting the efficiency of the engine by taking advantage of the expelled pressure from the exhaust.
It is expressed mathematically in degrees of shaft rotation.
So, Technician B is very correct.
Answer:0.3
Explanation:
Given
velocity of car=15 m/s
truck brought to halt in a distance of 38 m
We know
Final velocity (v)=0
(deceleration)
Therefore minimum coefficient of friction \mu will be
Part A)
Distance is given as sum of total path length
So here as we are given that car drives 40 miles East and 30 miles West
So here the total path length is
Part B)
Displacement is given as straight line distance between initial and final position
So here we can see that
East
West
Now the total displacement will be
<u><em>so the displacement will be 10 miles East</em></u>
I would say B , not sure if its correct
