Answer:

has a radius of 2439 km (1524 mi), and the metallic iron-nickel core is believed to make up about 75% of this distance. Measurements of the planet's magnetic field made by Mariner 10 as it flew by the planet indicates that this core is likely to be hot and fluid.

Imagine that you work for a conservation organization. Your job is to make recommendations to restore an area of a prairie that
ella [17]

Answer:

The damaged prairie area can be restored through <em>site preparation, replanting and putting species back on the landscape.</em>

Explanation:

Prairie- this is a type of habitat with mostly grasses. It also consists of trees, occasional shrubs and flowering plants. This can be found around the world and is <em>ecologically important for providing habitats for native animals and insects.</em> It is perfectly adapted to the climate and<u><em> requires minimal maintenance.</em></u>

Once a prairie is damaged, it becomes an essential move to restore it immediately. This can be done through different human activities such as the following:

1. Site preparation- before doing anything else, it would be best to prepare the prairie site by removing debris from the fire. This will make everything easier once you start planting the crops or plants.

2. Replanting- this is probably the most essential move you can do. It would be best to plant high quality food plants that would provide nectar, pollen and seeds throughout the season. This will entice many birds and butterflies into the area. It will also make the native plants abundant which will, in turn, increase ecological diversity.

3. Putting species back on the landscape- when a wildfire occurs, it is a common sense that species also run away from their home (habitat). In order to create that natural habitat again, it would be best to put the species back to where they belong so they can restart their lives. This will resume the natural food webs and nutrient cycles.

The heating element in a kettle behaves like a resistor. A particular kettle needs to operate at 230 V, with a power of 1500 W.
dedylja [7]

Answer:

R = 35.27 Ohms

Explanation:

Given the following data;

Voltage = 230V

Power = 1500W

To find the resistance, R;

Power = V²/R

Where:

V is the voltage measured in volts.

R is the resistance measured in ohms.

Substituting into the equation, we have;

1500 = 230²/R

Cross-multiplying, we have;

1500R = 52900

R = 52900/1500

R = 35.27 Ohms.

Therefore, the resistance which the heating element needs to have​ is 35.27 Ohms.

La velocidad del sonido en el aire es 340 m/s. Desde que se produjo el relámpago hasta que se oyó el trueno han transcurrido 8 s
scoundrel [369]

Answer:

Distancia = 42.5 metros

Explanation:

Dados los siguientes datos;

Velocidad del sonido = 340 m/s

Tiempo = 8 segundos

Para encontrar la distancia desde la que se escuchó el sonido;

Distancia = velocidad/tiempo

Sustituyendo en la fórmula, tenemos;

Distancia = 340/8

Distancia = 42.5 metros
