Answer:
Tension is also known as Force...
and Force is mass× acceleration.
so....1000×0.70=700N
Ok so we know:
The time (t) is 18seconds
The acceleration (a) is 2.2m/s2
The displacement (r) is 660
Using the equation

With 'u' being the initial velocity we want, we get:

So:

So:

So the original/initial velocity was 16.8666 or 16.87 m/s
Hope this helped
Answer:
The cloud moves 9050 meters to the east in 12.5 minutes.
Explanation:
Let suppose that mass of the cloud is negligible. meaning that effects of gravity are negligible and that altitude of the cloud remains constant. If the cloud drifts at constant velocity, travelled distance is defined by following formula:
(1)
Where:
- Velocity, in meters per second.
- Time, in seconds.
If we know that
and
, then the travelled distance after 12.5 minutes is:

The cloud moves 9050 meters to the east in 12.5 minutes.
1: Evaporation, this accounts for the most
2: Transpiration, second most
3: Sublimation, third most
Answer:
Eighteen percent
Explanation:
Eighteen percent of all electricity in the US is sourced from renewable energy ,which includes solar , wind, and hydroelectric dam.
Hydroelectric power is currently the largest producer of renewable electricity in the US, generating around 6.5% of the nation's total electricity as well as 45.71% of the total renewable electricity generation.The United States is the fourth largest producer of hydroelectricity in the world after China, Canada and Brazil.
