Answer: LET'S TAKE GRAVITY ON EARTH AS 10 N/KG AND ON MOON AS 0.6 N/KG

a) weight=15kgx10N/kg

               = 150N

b) weight=15x0.6=9N

c) mass=is the same so 15kg

d) mass is measured in kg, weight in NEWTONS OR KG M/S^{2}

e) when the gravitational force is zero

Almonds cost $3.49 per pound. A bag of almonds costs $6.95. to the nearest whole pound, about how many pounds of almonds are in
abruzzese [7]

The hint in this problem is in the word "about" or approximately how many pounds.

So we could find the solution by estimation through rounding off.

 

We know that almonds cost about 3.50 per pound and a bag costs about $7.00.

Dividing 7 by 3.50 per pound, will give us $7 ÷ $3.50 = 2 pounds.

The answer is 2 pounds.

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.
