What direction does the Earth rotate?

The Earth's axis of rotation leans at an angle of approximately 23.5 degrees, referred to as "obliquity" of the planet's axis. The apparent annual course of the sun through the stars, known as the ecliptic, is tilted with respect to the same angle as the rotational axis of the Earth. As the Earth rotates around its axis, the apparent movement of the stars across space appears to change relative to the location of the observer. As the observer draws near the South Pole, the Earth appears to move in an east-to-west direction, instead of the west-east direction when viewed from the N..

What is 375 degrees Fahrenheit in degrees Celsius?

Using the formula, 375 degrees F is equal to 5/9 x (375 - 32) degrees C. The answer works out to 5/9 x 343, which is equal to 190.55555555. Rounding to three decimal places, it becomes 190.556 degrees C. To check the answer, convert back to Fahrenheit by using the formula Fahrenheit = 9/5 (Celsius)+32. Fahrenheit = 9/5 x (190.556) +32, which is approximately equal to 375 degrees F.

How are thunderstorms measured?

According to Weather Online, thunderstorms are formed when air parcels rise through the atmosphere after being heated by the sun. After the air rises, it begins to cool, which results in condensation and the formation of cumulus clouds. As the air continues to travel vertically, the cumulus cloud transforms into a cumulonimbus cloud. Cumulonimbus clouds are capable of producing strong winds, thunder, lightening, intense rain and tornadoes. They can reach heights of up to 20 kilometers above the Earth's surface.\nThere are two types of thunderstorms: air mass thunderstorms and severe thund..

What affects the bounce height of a ball?

The elasticity of a material is the ability it has to revert back to its original shape after it is changed. When the ball hits a surface, the pressure of the material reverting back to its shape causes it to bounce. Rubber, for instance, has a high amount of elasticity and is more prone to bounce. The more air pressure a ball has in it, the higher it will bounce as well.

What macromolecule made by plants is burned in the mitochondria?

Plants are considered autotrophs due to their ability to create their own energy sources. Plant cells contain chloroplasts, an organelle that undergoes photosynthesis to harvest energy. During photosynthesis, the plant uses light energy obtained from the sun to convert carbon dioxide and water to the chemical energy present in glucose and releases the byproduct oxygen.\nAnimals, because they are heterotrophs, lack the ability to create their own energy sources and must instead consume organic carbon created from other organisms. Animals consume the glucose produced by plants and burn that usin..

What is the size of the largest asteroid?

Ceres is so large that it makes up one quarter of the total mass of the asteroid belt it calls home, which lies between Mars and Jupiter. It is large enough to be mostly spherical. Scientists believe that it has a rocky core enclosed in ice, which is in turn enclosed by a thin outer crust. Ceres has an eccentric orbit, which makes its distance from the sun vary between about 2.6 and nearly 3 astronomical units (each unit is roughly the distance from the Earth to the sun).

What is the chemical symbol for water?

Water is written as H2O or HOH because every molecule of water contains two hydrogen atoms and one oxygen atom. These three atoms are bonded together through covalent bonding. Covalent bonding allows for these atoms to share their elections, enabling fluidity. The opposite of covalent bonding is ionic bonding, which does not allow for transferring of electrons. Water is the only substance that exists naturally as a solid, liquid and gas.

What are three statements that define all living things in terms of cells?

There are three statements regarding cells that make up the cell theory published by Schwann. One is that cells are the units of organization, physiology and structure in all living organisms. The second is that new cells are spontaneously generated, much like crystals. Finally, Schwann believed the cell was a distinct entity in addition to a structural building block in living organisms.\nAlthough Schwann published this theory alone, Matthias Schleiden helped formulate the theory by describing the nuclei of plant cells. Schwann felt these cells were similar to the animal cells he had observed..

What is the formula for sulfur hexafluoride?

Sulfur hexafluoride is a man-made gas that is odorless, colorless, non-flammable and water-soluble. Additionally, the EPA has determined that it has the greatest potential negative impact on the environment among all greenhouse gases. Over a 100-year period, the potential global environmental impact of sulfur hexafluoride is more than 22,000 times the potential impact of carbon dioxide. However, the ratio of the gas in the atmosphere is minimal, preventing it from significantly contributing to global warming.

When a nucleus emits a positron, what happens to its atomic number?

During positron emission, the proton moves from the parent nucleus to the daughter nucleus in its conversion to a neutron. The nucleus then emits a neutrino and a positron. A positron is a positive particle with the same mass as an ordinary electron, but it has the opposite charge.\nPositron emission was discovered by Irène and Frédéric Joliot-Curie in 1934 as one of the three processes of beta decay.
