Answer:
Difference between science and technology
Explanation:
The words science and technology can and often are used interchangeably. But the goal of science is the pursuit of knowledge for its own sake while the goal of technology is to create products that solve problems and improve human life. Simply put, technology is the practical application of science.
Science encompasses the systematic study of the structure and behaviour of the physical and natural world through observation and experiment, and technology is the application of scientific knowledge for practical purposes.
Science is the study of the natural world and how it works. Technology puts scientific knowledge to work to solve problems, either by building things or by finding new ways to do things.
Scientific knowledge is used to create new technologies. New technologies often allow scientists to explore nature in different ways and make new discoveries. Examples of technologies that have helped science advance include the telescope and microscope.
The conclusion was “that most scientific fields are much more strategically important to technology than data on direct transfers of knowledge would lead us to believe”
In today's world, the role of science and technology is indispensable. We need Science and Technology in every sphere of our life like to treat diseases such as cancer or even to book a cab or train/flight ticket. In fact, without technology (integrated with science), we cannot imagine our life per se.

I think the last option is the correct answer. <span>The powder increased the hydrogen ion concentration of the solution. The said statement is the inference we can make from the situation. pH is the measure of hydrogen ions in a solution. The powder when added in the solution most likely dissociates into ions, especially hydrogen ions, thus decreasing the pH.</span>
The average atomic mass of Sn is 118.71 g/mol
the percentage of heaviest Sn is 5.80%
the given mass of Sn is 82g
The total moles of Sn will be = mass / atomic mass = 82/118.71=0.691
Total atoms of Sn in 82g =
the percentage of heaviest Sn is 5.80%
So the total atoms of = 5.80% X
Total atoms of = atoms
the mass of will be =
Answer: Wheel and axle
Explanation:
Wheel and axle is the best answer. Technically that's not the primary part that steers a vehicle though. A pulley is in the engine and I've never heard of wedge and first class lever. The question isn't too clear, but yea, I would pick ii if I was in your spot.
