Answer:

The fuel for nuclear fusion is often uranium
Nuclear fusion is used to generate electricity at nuclear power plants

Explanation:

The most common nuclear fuel is made up of fissile elements such as Uranium, Neptunium, Plutonium, Americium and Curium, which are fissionable elements, which is when its nucleus is capable of undergoing a fission with neutrons free of any energy.

Nuclear fission can be used both for warlike purposes, as in the construction of atomic bombs, as well as for pacifist purposes, in the construction of reactors for the production of electrical energy.

suppose you're outside on a hot date and you moving to the shade of a tree which form of energy transfer are you avoiding?

Answer:

Radiation

Explanation:

A sun transfers energy by radiation. However, there are three different modes of heat energy transfer -

a) Radiation

b) Conduction

c) Convection

Since sun is a at a very far distance from earth, it cannot transfer its heat energy by conduction as for this mode of heat transfer two bodies need to be in touch with each other.

For convection mode of heat transfer a medium is required but for transfer of sun's energy (which is electromagnetic radiation) no medium is required.

Hence, Sun will transfer energy by radiation only.

Antarctica, almost completely covered in ice, has an area

Marysya12 [62]

<u>Answer:</u> The mass of ice is $2.39\times 10^{22}g$

<u>Explanation:</u>

We are given:

Area of Antarctica = $5,500,000mi^2=5,500,000\times 2.59\times 10^{10}=142.45\times 10^{15}cm^2$ (Conversion factor: $1mi^2=2.59\times 10^{10}cm^2$ )

Height of Antarctica with ice = 7500 ft.

Height of Antarctica without ice = 1500 ft.

Height of ice = 7500 - 1500 = 6000 ft = $182.88\times 10^3cm$ (Conversion factor: 1 ft = 30.48 cm)

To calculate mass of ice, we use the equation:

$\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}$

We are given:

Density of ice = $0.917g/cm^3$

Volume of ice = Area × Height of ice = $142.45\times 10^{15}cm^2\times 182.88\times 10^3cm=26051.26\times 10^{18}cm^3$

Putting values in above equation, we get:

$0.917g/cm^3=\frac{\text{Mass of ice}}{26051.26\times 10^{18}cm^3}\\\\\text{Mass of ice}=(0.917g/cm^3\times 26051.26\times 10^{18}cm^3=2.39\times 10^{22}g$

Hence, the mass of ice is $2.39\times 10^{22}g$
