Mary pushes her cart across the floor with a force of 150N for a distance of 10m. What is the work done on the cart?

Answers

Answer:

1500Joules

Explanation:

Work done, denoted by W, can be calculated using the formula:

Work done (W) = force (F) × distance covered (d)

According to the information in this question, Mary pushes her cart across the floor with a force (F) of 150N for a distance (d) of 10m.

Hence, work done (W) by the cart is:

W = 150N × 10m

W = 1500 Newton.metre (N.m) or Joules (J).

There are millions of organisms on Earth that scientists have classified into different levels of organization. The characteristics which would be most important to scientists when classifying the organisms will be the genes of the organism. Thus, the correct option is B.

What are the different levels of organization?

Taxonomy is the study of classification of organisms. Scientists have used many different types of information to place the different organisms into specific groups. The groups are arranged in different levels. These levels were named as kingdom, phylum, class, order, family, genus, and species.

The organisms which were present on the Earth were classified on the basis of the environment where they live, how small is the size of the organism, and the shape of the organism found such as rod-shape, cocci, spirillum, etc.

Therefore, the correct option is B.

The flooding of fields in winter can affect aquifers without having long term impacts on the height of the water table. Which statements explain why this is possible?

Select the TWO correct answers.

A. In winter, using groundwater to flood fields causes the water table to drop because water is withdrawn from the aquifer.

B. In winter, removing water from the aquifer causes the water table to rise because water covers the areas where rice is grown.

In spring, changes in the level of the river cause the water table to rise because water flows from the river into the aquifer.

C. In spring, removing water from the aquifer causes the water table to drop because water flows from the aquifer to the river.

D. In summer, changes in the level of the river cause the water table to rise because water flows from the river to the aquifer.

Answers

The flooding of fields in winter has no long-term effect on the height of the water table because removing water from the underground water  - the aquifer causes water to drop and summer melts water into the water table.

Aquifers, Water Tables, Summer, and Winter

During winter, the flooding of the field traps water from going back into the aquifers and the use of water from them causes the water level to drop.

Due to the melting of snow in summer, the water levels are normalized. Therefore, the correct answers are C and D.
