Which of the following is NOT a proposed method of interstellar travel?
A. Bussard Ramjet
B. Interstellar fluid travel
C. Solar Sail
D. Warp Drive

Answers

Answer 1

Answer: C. solar sail

Explanation: hope I'm right if I'm wrong I'm sorry

Answer 2

Answer: C (Educated Guess, read about wind below)

Explanation:

It’s a guess, more so a presumption. A solar sail would require what a sail on earth does to make its main part move..... wind flow. Yet wind flow, aka convection, is caused by the sun warming air on different parts of the earth, increasing its pressure, pushing away cold air, creating wind. There isn’t any surface in space that the heat can build upon... not knowing anything about the other choices, this about choice C is enough to convince me that it is the one that is not effective.

Why is it important to hear the water for this investigation? What heats the water in the oceans, lakes, and rivers found on Earth?

Answers

Answer:

The water in ocean, lakes and rivers are heated by the Sun, sunlight hits the ocean which is dispersed by the first 1000 meters of the oceans surface. This hot water is mixed with the cold water at the bottom of the ocean by ocean waves and this is the reason why ocean waves are at a regular temperature.

In a lake the water is heated the same way but there is not much water to mix the hot water with the cold so the water in the lake seems hotter than the ocean.

In a river the water keeps on flowing which mixes the hot water with the cold and the temperature remains regular.

Explanation:

Sound is a wave which is created by vibration, and these sound waves can travel in different mediums for example, air, liquid and even solid.

Help ASAP 20 points! i'm doing a CER for science and i need the evidence.... It's about Oxbow lakes! Thank you and PLEASE ANSWER NOW!

Answers

Answer: An oxbow lake starts out as a curve, or meander, in a river. A lake forms as the river finds a different, shorter, course. The meander becomes an oxbow lake along the side of the river.

Oxbow lakes usually form in flat, low-lying plains close to where the river empties into another body of water. On these plains, rivers often have wide meanders.

Meanders that form oxbow lakes have two sets of curves: one curving away from the straight path of the river and one curving back. The corners of the curves closest to each other are called concave banks. The concave banks erode over time. The force of the rivers flowing water wears away the land on the meanders concave banks.

The banks opposite the concave banks are called convex banks. The opposite of erosion happens here. Silt and sediment build up on convex banks. This build-up is called deposition.

Erosion and deposition eventually cause a new channel to be cut through the small piece of land at the narrow end of the meander. The river makes a shortcut. Oxbow lakes are the remains of the bend in the river.

Oxbow lakes are stillwater lakes. This means that water does not flow into or out of them. There is no stream or spring feeding the lake, and it doesnt have a natural outlet. Oxbow lakes often become swamps or bogs, and they often dry up as their water evaporates.

Oxbow lakes can be rich wildlife habitats. Along the Amazon River in South America, oxbow lakes are common and their still waters provide a unique habitat for plants and wildlife. Giant river otters frequently live in the Amazons oxbow lakes, and feed on about 5 kilograms (11 pounds) of fish per day.

People often create oxbow lakes. The Mississippi River is shorter now than it was in the 19th century, for instance, because engineers have cut off hundreds of meanders. This created hundreds of oxbow lakes. These lakes eventually dried up to create acres of land for farming, housing, and industry.

An oxbow lake gets its name from the U-shaped collar placed around an oxs neck to which a plow is attached. It can also be called a horseshoe lake, a loop lake, or a cutoff lake.

THE​

Answers

Answer:

8.48 hours

Explanation:

Given that:

120 miles = 2.4 hours

Speed = distance / time

Speed = 120 miles / 2.4 hours

Speed = 50 miles per hour

Time taken to drive 424 miles

Using the relation :

Time taken = distance / speed

Time taken = 424 miles / 50

Time taken = 8.48 hours
