Q: Q: Body waves and surface waves are the two major types of what, which occur during earthquakes? Read this paragraph and choose the correct option from the provided answers: There are two major types of seismic waves. Body waves travel through the Earth's interior. Surface waves travel along the ground surface. In an earthquake, body waves are responsible for sharp jolts. Surface waves are responsible for rolling motions that do most of the damage in an earthquake. Choices: - tidal waves - current waves - sound waves - seismic waves A:
A: seismic waves

Q: Q: Electric substations have what devices, which use electromagnetic induction to increase or decrease the voltage of the current? Read this paragraph and choose the correct option from the provided answers: Electric substations have several functions. Many substations distribute electricity from a few high-voltage lines to several lower-voltage lines. They have electric transformers, which use electromagnetic induction to change the voltage of the current. Some transformers increase the voltage; others decrease the voltage. In the Figure below , you can see how both types of transformers are used in an electrical grid. Choices: - transistors - generators - tubes - transformers A:
A: transformers
