Answer:

Yes.

Explanation:

51/17 is a rational number because "A number is considered a rational number if it can be written as one integer divided by another integer."

Yes it is, because it is expressed in form a/b, it would be irrational if it had a square root for example

Annette [7]
Answer - 12,900 Newtons

Explanation

First, we find the volume of the water
Volume = Area * Heinght
= 1.5 m² x 7 m
=  10.5 m³
 
Covert the volume to liters
1 m³ of water = 1000  liters
10.5 m³ of water = 10.5 m³ * 1000 liters liter/m³
= 10,500 liters
 
Use the volume of water to calculate the mass
1 liter of water weighs 1 kg
10,500 liters of water = 10,500 * 1 kg/liter
= 10,500 kg
 
Now, we can calculate the force of gravity on the water
Force of gravity on the water = Weight of the water
Weight = Mass * Acceleration
 
Mass = 10,500kg
Acceleration (due to gravity) = 9.8 m/s²

Force of gravity on the water
= Weight of the water
= Mass * Acceleration
= 10,500 kg * 9.8 m/s²
 = 102,900 Newtons

The town of seaside needs to build a new power plant the old coal burning plant produces too much pollution and if no longer saf
drek231 [11]

To generate clean energy the mayor my build the fooling type of energy plants:

wind farms

solar power plants

wave power plants

Explanation:

At the seaside there are winds all over the year and that can be transformed in electrical energy by a wind turbine. The mayor can build a on-shore wind farm (reduced consts) and may also build off-shore wind farms (but these have an increased cost).

The second option is to build solar power plants. It will be cost effective if the people in the town will install solar panels on the building roofs. In this way you decrease the costs with the transportation of electrical energy.

The third option is to install wave power plants which harvest energy from the sea waves. It is a rather new technology, in comparison with the other two, but the initial consts can be amortized over time.

All three options will provide clean energy.

Right now nuclear plants have a very expensive initial costs and they may not be afforded by small towns.
