Changes to landscapes are most commonly viewed above ground; however, they are also visible underground. As shown in the picture, changes can be seen underground in the form of rocky trenches caused by tectonic plate movement, altering the topography of the ocean floor. Another way changes to landscapes can be observed underground is by studying caves and their slowly growing stalagmites, sinkholes, and shifts in their soluble rocks.

An inference can be made that the higher something’s speed is, the more energy it has. Higher amounts of energy will result in a more significant change of motion for the object it is acting on. When the speed decreases, the distance the object moves also decreases. There is a direct relationship between speed and energy. A motorcycle driving down the road has the most speed and energy.

Metal is the best conductor of heat because its atoms are arranged in a way that allows electrons to travel freely, meaning they can pass energy more quickly.

To answer this question, we need to recall the formula for speed:

We can plug in the known values from the question to solve:

If London is waiting at the bottom of the hill and Glen crashes into him there will be a change in the energy transferred when the collision takes place. When Glen hits the back of London his sled will stop or slow down while London's sled will be pushed forward and move. There is a transfer of energy from Glen to London that takes place when any two objects collide.

The diagram that correctly depicts the relationship between force and motion is Diagram B. The force of an object is colliding with the white sphere and pushing it forward. The sphere will move in the direction it is being pushed. If two objects collide, energy will be transferred between both, and there will be a change in motion.

A toaster is an example of how a device can convert electrical currents into heat energy. The toaster is plugged into the electrical outlet and electricity flows through the cord and into the heating elements of the toaster. The toaster than warms and crisps the food item placed inside. The heating coils warm the bread as a result of electrical currents being transferred.

Because electricity is the flow of electrons, or negatively charged particles in atoms, conductors are necessary when trying to transfer energy through electrical currents. Conductors allow electrons to flow easily, which in turn transmits energy. Someone would not want to block electrons from traveling whatsoever when trying to create an electrical current - materials that do this would be called insulators.

Sound waves must travel through a medium. This medium can be a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. Sound travels fastest through solids. Molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to move more quickly through it.

Each of the examples in this question are scenarios in which sound would be transferred because they all cause vibrations that travel through a medium.
