How do you make a battery with Coke and vinegar?

Prepare the soda and aluminum stripsPour the soda into the cups, and set all three aside. Cut the aluminum can into three strips, each 1 inch wide and as tall as the can itself. If the cups are shorter than this, the strips can also be shorter.Sand the aluminum strips cleanSand the strips of can until all the paint and plastic are completely removed from the surface on both sides.Place aluminum and copper stripsPlace one strip of sanded aluminum and one strip of copper into each cup, allowing them to protrude over the top. Do not allow the strips of metal to touch each other.Attach connectorsS..

What is the climate of freshwater biomes?

On average, freshwater biomes see temperatures of 51 degrees Fahrenheit to over 100 degrees Fahrenheit. Freshwater biomes are found all over the world except in the Antarctic. Due to the wet and warm weather in the biomes, they are home to a large array of plant and animal life. They are also home to many bird, reptiles and insect species. Another type of wetland is a saltwater biome. This type is also found all over the world and is home to many species of plants and animals.

What are milliamps?

According to the National Institute of Standards and Technology, an ampere is equal to the current which, if allowed to travel through two parallel, straight conductors of infinite length and negligible cross sectional area placed in a vacuum with a space of 1 meter between them would generate a force of 2.0 x 10^-7 Newtons per meter. One milliampere is equal to one one-thousandth of this current. An ampere is also equal to one coulomb of charge per second.\nThe Ampere is named after Andre Marie Ampere, a French mathematician and physicist who lived from 1775 to 1836. Andre Marie Ampere was a ..

What is the slowest living creature on Earth?

Sloths have very powerful claws and are built for life in the tree tops, which is where they spend move of their lives, whether it is eating, sleeping or mating. Although it is true that sloths are extremely slow on land, they are actually very capable swimmers. A sloth can grow to be as long as 23 inches and can weigh up to 8.75 pounds.

How does comparative embryology support the theory of evolution?

Furthermore, the embryo serves as a microcosm for evolution. The embryo passes through many stages of evolution until it finally reaches its adult form.\n\nWhile the appearance of ancestral traits in the embryos of many organisms is well documented and can provide insights into the evolution of a species, an early attempt to draw direct parallels between the development of an embryo (ontogeny) and the development of its species (phylogeny), known as the Recapitulation Theory, is widely believed to have been discredited by later science.

With what organs does the vagus nerve interact?

The vagus nerve receives information from these organs and communicates it to the brain. The vagus nerve is responsible for the gut instinct of fear that people feel in a fight-or-flight situation, states Psychology Today. As part of the involuntary nervous system, the vagus nerve keeps heart rate constant and regulates food digestion, says Healthline.

How does the concept of "power" relate to work in physics?

For the same amount of work, power and time are inversely proportional: with more power the same amount of work can be done in less time. Machines are given power ratings for this reason, as although machines are designed and built to do work, the time frame in which they do the work is also important.\nFor example, a car's horsepower rating is a measurement of power. If a car's 40-horsepower engine accelerates it from 0 to 60 mph in 16 seconds, then the same car with four times the power - a 160-horsepower engine - can accelerate it to 60 mph in 4 seconds, which is one-fourth the ti..

What is the main secretion of the esophagus?

The mucus is produced by mucous glands located in the mucosa, the lining of the esophagus. This lining is composed of stratified squamous epithelium, which is resistant to trauma from abrasive foods. During swallowing, boluses of food distend the esophagus, causing mucus to be expressed from the mucous glands. Peristaltic contractions then propel the food into the stomach. In humans, it takes four to five seconds for a bolus of food to go through the esophagus.

What are some good science projects about kinetic energy?

Making the magic can requires a coffee can, a nail, a 9-volt battery, two paper clips, tape and a rubber band. Make a hole in the bottom and lid of the can. Tape the battery to the center of the rubber band, make sure that both sides of the rubber band are attached to the underside of the battery. Put the loops of the rubber band through the two holes before clipping and taping them in place. Tighten the rubber band If the battery touches the side of the can when the can rolls. As the can rolls, the band twists, and the can slows down. When the can stops, the band starts to untwist, and the ca..

What does renewable mean?

The word "renewable" dates back to 1727 from the stem "renew" and the suffix "able." Using the word in reference to energy sources started in 1971. A renewable resource is one that can be replenished over the passage of time through biological reproduction and other natural processes. These include wind, sunlight and water resources. A renewable contract is one that can be continued for a longer period of time than the original.
