Answer:

Part) A

Density=Mass/volume

Part) B

volume displaced by crown> volume displaced by gold brick

Step-by-step explanation:

Density=Mass/volume

Mass=Density(volume)

The jeweler replace gold with equal weighed silver but as gold has a higher density than silver, the jeweler must put more volume of silver to balance it. Hence the overall volume of crown increases.

2. In bath, Archimedes discovered that the amount of water displaced in tub is equal to the volume of the body that was placed in it.

He then compares the volume of water displaced by a gold brick and the volume of water displaced by the jeweler made crown and when the volumes do not come equal then there is evidence. The volume of water must rises higher in case of crown than in case of brick of gold due to inclusion of silver in it!

Answer:

A) from definition:

density = mass/volume

mass = density*volume

Given that the jeweler replaced “an equal weight” (or equal mass) of gold with silver:

(density*volume) of gold = (density*volume) of silver

Gold is more dense than silver, then the volume of silver was greater than the volume of gold replaced

B) He discovered that the volume of displaced fluid is equivalent to the volume of the object fully or partially immersed in it.

He was very excited because he could solve the problem.

I predict that next he compared the volume of a bar gold with the same weight of the crown with the volume of the crown, and checked that the volume of the crown was greater

Juan has 4 1/2 gallons of blue paint. Each wall in his house will need 3/4 of a gallon of paint. How many walls can Juan paint b

Lostsunrise [7]

We know that

4 1/2 gallons-------> (4+2+1)/2-----> 9/2 gallons

1 wall in the house will need --------> 3/4 of a gallon of paint
 X wall-----------------------------------> 9/2 gallons
x=(9/2)/(3/4)----> 9*4/2*3-----> 36/6----> 6 walls

the answer is
6 walls

Nuclear Power is a perfect example of exponential relations. Canada produces over half of its electricity using nuclear reactors

mario62 [17]

Solution :

Nuclear fission is exponential. With uranium atoms arranged properly it is possible to have the fission effect and cause more and more uranium nuclei to fission. This is known as chain reaction and a number of uranium atoms are fission together to increase exponentially.

Canada, for example produces electricity using the process of fission process in its nuclear reactors.

But one of the problems with nuclear reactors is its disposal of the nuclear waste. The nuclear waste includes the used reactor fuel, uranium mill tailings and other radioactive wastes. They remain radioactive and are dangerous for the human health.

A). The long term nuclear waste are stored in deep excavations and covered with rocks and mud so that the harmful radioactive materials does not escape from them. They are also stored in some high density and thick cylinders and remained isolated in the dump yard from the people and nature.

B). Canada has a high source of renewable sources of energy. This is a clean source of energy and Canada can make best use of it. Most of the energy requirement of Canada can be taken care off by using wind energy. Canada is planning to set up wind energy mills in most of its part and generate electricity from it.

Canada has also installed several solar power projects which is clean and can help the people to use this solar energy to produce electricity.
