Which of the following are good safety measures during the thunderstorm?


D.) go inside a close building

The options that are good safety measures during a thunder storm are D.) Go inside a closed building and E.) Talk on a phone with a cord.

What are good safety measures during a thunder storm?

During a thunder storm, safety measures are crucial to minimize the risk of lightning-related accidents. A, B, and C are not safe options. A, which suggests crouching with just the balls of your feet in contact with the ground, doesn't provide adequate protection from lightning strikes. B, relying on rubber-soled shoes, is a misconception as rubber doesn't significantly protect against lightning. C, standing under a tree, is hazardous due to the tree's height and the increased risk of being struck by lightning.

The recommended actions are D and E. Going inside a closed building is a safe option as it provides substantial protection from lightning strikes. Stay away from windows, electrical appliances, and plumbing. Talking on a phone with a cord (option E) is also safer than using a cordless or cell phone, as cords can conduct lightning away from you in case of a strike.

So, to ensure safety during a thunderstorm, the best measures are to seek shelter inside a closed building and use a corded phone if necessary. Remember that proper safety measures significantly reduce the risk of lightning-related accidents.

How did cultural beliefs and practices affect South Asia after the British colony of India was granted independence?

Answers

Answer:

Explanation:

The consequences of the partition of India and Pakistan were very severe. Lakes of people were forced to leave their lands and villages to escape terror and violence and death. Lakes of people irrespective of their religion lost their lives due to the Partition and the violence that followed.

After India gained independence from British colonial rule, cultural beliefs and practices played a significant role in shaping the development and identity of South Asia. Cultural beliefs and practices played a vital role in shaping South Asia after independence, contributing to the formation of a national identity, the preservation of cultural heritage, the development of governance and legal systems, the promotion of religious diversity and secularism, and the transformation of social and gender roles.

1. Formation of a national identity: Cultural beliefs and practices, including shared languages, religions, and traditions, played a crucial role in the formation of a national identity. India, with its diverse population, embraced the idea of unity in diversity and celebrated its cultural heritage as a symbol of national pride.

2. Preservation of cultural heritage: The independence movement in South Asia emphasized the importance of preserving cultural heritage. Efforts were made to revive and promote traditional art forms, literature, music, and dance, which helped foster a sense of cultural pride and identity.

3. Language and education policies: Language played a significant role in the post-independence period. In India, Hindi was adopted as the official language, while recognizing English as an associate official language to ensure continuity and inclusivity. Regional languages were also given importance, as they were seen as crucial to preserving cultural diversity.

4. Influence on governance and legal systems: Cultural beliefs and practices had an impact on the development of governance and legal systems. Concepts of justice, equality, and social welfare were shaped by cultural values and traditions, and efforts were made to ensure that legal systems were in harmony with cultural beliefs and practices.

5. Religious diversity and secularism: South Asia is known for its religious diversity, with major religions such as Hinduism, Islam, Sikhism, Buddhism, and Christianity being practiced in the region. Post-independence, efforts were made to promote religious tolerance and secularism, ensuring equal rights and protection for all religious communities.

6. Impact on social and gender roles: Cultural beliefs and practices influenced social and gender roles in South Asia. Efforts were made to challenge and reform traditional practices that were discriminatory towards women and marginalized groups. The promotion of education for all, including women, aimed to empower individuals and challenge traditional norms.

At the East African Rift, the African Plate is separating into two smaller plates that are moving in opposite directions. Based on this, which type of boundary exists at the East African Rift? 

      A. Transform  B. Divergent  C. Subduction  D. Convergent

Answers

Your answer would be B, or divergent.

Let's go through what each of these boundaries are.

Transform: When two plates move along their boundary. For example, if you were looking at a boundary running north to south, one plate would be shifting north, the other south.

Divergent: When two plates are moving away from each other, and new land is being made in between them.

Convergent: When two plates are moving towards each other, and land is being destroyed between them.

(Subduction is not a boundary, it has to do with earthquakes but that is a subduction zone, not boundary).

What is being described here sounds to be along the lines of a divergent boundary, as the African plate is separating while moving in opposite directions. This means that the two plates are moving away from each other.

Therefore, I would say the boundary of the East African Rift is a divergent boundary.

Hope this helped!

Jews are permitted to eat what kinds of food?
foods that meet the dietary guidelines of a diabetic
foods that are gluten free
foods that are Kosher and meet the dietary laws known as Kashrut.
foods that contain NutraSweet

Answers

Foods that are Kosher and meet the dietary laws known as Kashrut.

Final answer:

Jews are allowed to eat foods that adhere to the Kosher dietary laws, known as Kashrut. These laws dictate certain prohibitions and preparation methods for food that are unique to Judaism and not necessarily related to diabetic or gluten-free dietary restrictions.

Explanation:

Jews are permitted to eat foods that are Kosher and meet the dietary laws known as Kashrut. These dietary guidelines are part of the Jewish tradition and involve a series of rules about what foods can be consumed and how they must be prepared. The key elements include prohibitions against certain animals like pork and shellfish, the separation of meat and dairy products, and the requirement for meat to be slaughtered and prepared in a specific way.

While those with diabetes must monitor their sugar intake and may use artificial sweeteners like NutraSweet (aspartame), and those with celiac disease need to consume gluten-free foods, these dietary restrictions are not specifically tied to being Jewish. Similarly, while many foods on the market address the needs of specific health conditions or preferences and may be kosher as well, the primary concern from a Jewish dietary standpoint is that they adhere to Kashrut.

19. Which type of volcano is shown in the image?

A. Shield volcano
B. Fissure
C. Ash-cinder volcano
D. Composite volcano

Answers

The type of volcano shown in the image is known as fissure volcano.

What is the characteristics of fissure volcano?

Fissure volcanoes are characterized by long, narrow cracks or fissures in the Earth's crust through which lava erupts. Unlike typical conical volcanoes, fissure eruptions produce extensive lava flows rather than explosive eruptions with ash clouds.

These volcanoes are associated with divergent plate boundaries, where tectonic forces cause the Earth's crust to stretch and crack, allowing magma to reach the surface. Fissure eruptions often occur in linear patterns, producing chains of volcanic vents. They can also lead to the formation of extensive lava plateaus or basalt plains.

Which triangle criterion can you use to prove that ABC AND ABD are congruent?

Answers

Answer: Based only on the facts in the diagram, you can see that:

BC≅BD (given);

∠ABC is right, ∠ABD is also right, because these two angles are supplementary and together form the straight angle;

AB is common side.

You have two pairs of congruent sides and a pair of included congruent angles that are adjacent to the congruent sides. So you can use SAS Postulate  correct choice is A.  hope this answer helped you :)

Explanation:

Final answer:

To demonstrate the congruence of triangles ABC and ABD, the Angle-Side-Angle (ASA) or Side-Side-Side (SSS) congruence criteria can be used, depending on the given information about the angles and sides.

Explanation:

To prove that triangles ABC and ABD are congruent, we need to use one of the congruence criteria for triangles. Since segment AB is shared by both triangles, if we also know that two angles are the same such as angle BAB' in one triangle corresponding to the angle of incidence in the other, and another pair of sides like AC and AD is equal, we could use the Angle-Side-Angle (ASA) criterion for congruence. Alternatively, if we know that side AB is equal to itself (by the Reflexive Property), and two other sides are equal in length, we could use the Side-Side-Side (SSS) criterion.
