The electrical energy consumed in one year by using the light bulbs is 8,760 kWh.

The given parameters:

  • Number of light bulbs = 10
  • Power consumed by each bulb = 100 W
  • Time of energy consumption, t = 1 year

<h3>What is electrical energy?</h3>

This is the electric power consumed or dissipated at a given period of time.

The  electrical energy consumed in one year by using the light bulbs is calculated as

E = Pt

E = (100 \times 10) \times (1 \ yr \times \frac{8760 \ hrs}{1 \ yr} )= 8,760,000 \ W att-hours\\\\&#10;E = \frac{8,760,000 }{1000} = 8,760 \ kWh

Thus, the electrical energy consumed in one year by using the light bulbs is 8,760 kWh.

Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.

Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.

Solids can be hard like a rock, soft like fur, a big rock like an asteroid, or small rocks like grains of sand. The key is that solids hold their shape and they don't flow like a liquid.

How do landforms and rock layers support the plate tectonic theory
Debora [2.8K]
In plate tectonics, Earth's outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.

Tectonic processes build landforms mainly by causing the uplift or subsidence of rock material—blocks, layers, or slices of the Earth's crust, molten lavas, and even large masses that include the entire crust and uppermost part of the planet’s mantle.

These support the tectonic theory by showing they are byproducts and are substantial evidence to show how the tectonic theory impacts earth.

Hope this helps!
