describe the diffrence between a closed circuit and an open circuit

Answers

Answer 1

Answer:

An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout.

Explanation:

For instance, a simple light switch opens and closes the circuit that connects a light to a power source. When you build a circuit, it's a good idea to disconnect the battery or other power source when the circuit is not in use.

A pool of standing water could be hiding __________ A. flash flood currents that could sweep your car away. B. deep sinkholes. C. all of the above.

Answers

Answer:

B. deep sinkholes

A pool of standing water could be hiding the deep sinkholes that are present in the pool for draining the water away. So, the correct option that matches with statement above is B.

Standing water refers to a condition of water in the pool when it is more still than the movements displaced by the way of waves and there is very less atmospheric pressure on the water.

When a water is in standing condition the reflection is more visible to the naked eyes as reflection is in greater number. So it is easier to see the water reflection in standing water in a pool.

After the water stays in standing condition for a while it will become smelly or dirty due to displacement in the water and the molecules begin to form bacteria under water.

One of the properties of standing water is to provide reflection and hence it becomes difficult to see through such water which makes the deep sink holes invisible.

Hence, the correct statement will be A pool of standing water could be hiding deep sinkholes present in the pools that drain away the water. And the correct option is B.

Hope this answer correct :)

Johannes Kepler was a German mathematician and astronomer who established that the Earth and planets move in elliptical orbits around the sun. the correct option is B, D, and E.

The following is a list of some of Johannes Kepler's accomplishments.

He made the planetary motion laws known. Kepler's rules, as they are now known, are still used to comprehend how the planets and other celestial bodies in our solar system move.He discovered that planets travel more quickly the closer they are to the sun. The second law of Kepler is known as this.He disproved the Ptolemy theory and demonstrated elliptical orbits. This significant advancement in astronomy backed the heliocentric hypothesis of the solar system.

Hence,  Kepler neither refuted Galileo's calculations nor revived Aristotle's theory of the solar system. so the correct statements are B, D, and E.

The process of __________ takes place when the Earth's surface is worn away by the action of physical processes such as wind and water.

Answers

Answer:

A

Explanation

The process of erosion takes place when the Earth's surface is worn away by the action of physical processes such as wind and water.

What is erosion?

Erosion is the action of surface processes that removes soil, rock or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited.

Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows.

The rates at which such processes act control how fast a surface is eroded.

Margo was angry her mother didn't pass "Ann Landers" on. C. Margo now writes the "Dear Abby" column, too. D. Lederer started "Ann Landers" to compete with "Dear Abby." Passage: Few people probably would have guessed that identical twin sisters Esther "Eppie" Pauline Friedman Lederer and Pauline Popo Esther Friedman Phillips would grow up to become two of the most influential advice columnists in the world. Dear Abby and Ann Landers were both known by their millions of daily readers for their quick wit and sage wisdom. The pair grew up in Sioux City, Iowa and attended Morningside College where they both worked on the newspaper staff. In 1939, at the age of 21, the Friedman sisters married in a joint ceremony. The original Ann Landers was started in 1942 by a nurse named Ruth Crowley. She wrote the column until her death in 1955. After she won a contest, Esther Lederer assumed the Ann Landers pen name and eventually won the copyright to it. Pauline Phillips founded Dear Abby in 1956. A rift between the twins developed when Life magazine reported that Phillips had offered the column to the Sioux City Journal at a discounted rate if it agreed not to run Ann Landers. Although they publicly reconciled in 1964, it is said the bitter rivalry continued behind closed doors for decades. In 1995, Phillips began to suffer from the onset of Alzheimers disease and her daughter, Jeanine, assumed the Abigail Van Buren pen name. Dear Abby has been in publication for more than 50 years and still read daily by more than 110 million people. Lederer was in good health most of her life and wrote Ann Landers until her death in 2002. She chose not to have another writer assume the pen name. Jeanine Phillips wrote a tribute to Ann Landers in Dear Abby shortly after her passing. Lederers daughter, Margo Howard, said the women had not been in contact for years, and she believes Phillips just wrote the tribute for money. Howard wrote an advice column of her own called Dear Prudence for several years. Currently, she pens Dear Margo. mona started making oatmeal cookies at 11:40 A.M.
