Every 6 seconds a pendulum completes 1 cycle. What are the period and frequency of this pendulum?

When heavy rain follows a dry season in the mountains, the land can change abruptly. For example, a mudslide can rush downhill as a huge mass of soil, water, and rock leaves a bare scar on the hillside. The correct option is A.

What is a mudslide?

A mudslide, also known as a debris flow or a landslide, is a rapid movement of a large mass of soil, rock, and water down a steep slope or hillside.

Mudslides typically occur after heavy rain, when water rapidly saturates the soil and creates a slurry of mud and debris. This slurry then flows downhill at high speeds, carrying with it anything in its path, such as rocks, trees, and buildings. Mudslides can be extremely destructive and dangerous, and they can cause significant damage to homes, infrastructure, and the natural environment.

Mudslides can occur in various parts of India, particularly in areas with hilly terrain and heavy rainfall. Some of the regions where mudslides have been known to occur in India are:

Uttarakhand: This northern state is particularly prone to mudslides and landslides, with the 2013 Uttarakhand floods and landslides being one of the worst disasters in recent history.

Himachal Pradesh: Another northern state with hilly terrain, Himachal Pradesh has also experienced numerous mudslides and landslides in the past.

Jammu and Kashmir: This state in the north of India is also prone to landslides and mudslides, particularly in the hilly areas.

Northeast India: The northeastern states of India, such as Meghalaya, Arunachal Pradesh, and Assam, are also prone to landslides and mudslides due to their hilly terrain and heavy rainfall.

Western Ghats: The Western Ghats, a mountain range that runs along the western coast of India, is also known for landslides and mudslides during the monsoon season.

It's important to note that mudslides can occur in other parts of India as well, and it's always important to be aware of the risks and take appropriate precautions.

Therefore,  mudslide is the correct option i.e A.

Answer:

A. mudslide.

Explanation:

This abrupt change can alter the surface, like mudslides, they are formed of water, rocks and water, like is described. This mudflow is capable to destroy vegetation, and leave behind fissures.

A  She can run the same distance in a shorter amount of time.

Explanation:

Jill can achieve a higher average speed than Jenna if she runs the same distance in a shorter amount of time.

Speed is a physical quantity that deals with the rate of change of distance with time:

          Speed =

The distance traveled is the length of the path covered and time taken is the duration.

To achieve a higher speed, it would be desired to have a lower time and the distance covered steadily increasing or staying the same.

To achieve a low speed, the distance must be decreasing and time increasing.
