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:
F=
Explanation:
The magnitude of force required to pull the lid off the box by air pressure.
We know that Pressure, P= Force(F)/Area(A)
Force, F= P×A
Given: A=
P=
.
Therefore, F=
.
F=
Let the cannonball be thrown at a height of h above ground.
Then the potential energy of the ball is
V = m*g*h
where
m = the mass of the ball
g = 9.8 m/s²
Also, the kinetic energy of the ball is
K = (1/2)mu²
where
u = 5 m/s, the vertical launch velocity.
Ignore wind resistance.
Because the total energy is preserved, the total energy (n the form of only kinetic energy) when the ball strikes the ground is
(1/2)mV²
where V = vertical velocity when the ball strikes the ground.
Expressions for both the initial and final energy are equal regardless of whether the ball s thrown downward or upward.
Therefore there is no difference in the landing speed.
Answer: There is no difference.
