حسنا ، قد يكون أحد الأمثلة على ذلك أن السطح مبلل أو جليدي ، لذلك لا يوجد احتكاك كافٍ للمشي.
Cancer research, solar panel production and agricultural innovation will all be key areas for nano tech, and so will clothing design, cosmetics manufacturing and many others are some of the new developments.
<u>Explanation:</u>
Nanotechnology is also being applied to or developed for application to a variety of industrial and purification processes. Purification and environmental cleanup applications include the desalination of water, water filtration, wastewater treatment, groundwater treatment, and other nano remediation.
Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources and life-saving medical treatments. Potential disadvantages include economic disruption and possible threats to security, privacy, health and the environment.
Answer:
a) D=-4273(x)-2327(y)
b) v=23.33m/s
c) V=-13.51m/s south of west.
Explanation:
In order to find the displacement we have to divide the motion on its X and Y components:
The total X displacement is the algebaric sum of the movement:
We have to do the same on Y:
D=-4273(x)-2327(y)
The angle is given by:
That is 28.57 degrees south of west.
the total displacement magnitude is given by:
The average speed is given by:
and the Average velocity is given by:
The average velocity is:
with an angle of 28.57 degrees south of west.
