A bullet travels at 850 m/s. How long will it take a bullet to go 1 km?
How many states have 21 year old minimum drinking age laws
By mid-1988, all 50 states and the District of Columbia had raised their purchase ages to 21 (but not Puerto Rico, Guam, or the Virgin Islands, see Additional Notes below). South Dakota and Wyoming were the final two states to comply with the age 21 mandate.Have a nice day
Oxygen is more reactive than nitrogen.
Oxygen is more reactive than nitrogen. Because triple bond between two atoms of nitrogen and there is double bond between two atoms of oxygen.Therefore, this statement is true.What do you mean by the reactivity ?
Reactivity is a substance's capacity to chemically react with other compounds. Iron, for instance, reacts vigorously with oxygen. Rust is a reddish powder that is created when it reacts with oxygen.
Because nitrogen has a higher dissociation energy than oxygen, its reactivity is lower than that of oxygen at the molecular level. Due to the triple bond that exists between the nitrogen atoms, the bond length of nitrogen is also shorter than that of oxygen.
Due to the strong triple bond between the atoms, the fact that all the valence electrons are in bonding orbitals, and the fact that more energy is required to excite them, Nitrogen is less reactive than Oxygen in the majority of gaseous processes.
Thus, Oxygen is more reactive than nitrogen.

A: Transformers work with either AC or DC electricity. True/False B: Power companies use high voltages to reduce power loss over long transmission distances. True/False
C: A(n) __________________ uses electromagnetic induction to increase or decrease voltage.
D: Materials that lose all electrical resistance at low temperatures are known as ____________________ and are ideal for constructing powerful electromagnets.
E: An electric device that uses an electromagnet to open and close a switch is a(n) ___________________.
A. False – Transformers are designed to work on AC
B. True – This is to compensate the losses as the length of wire increases
C. Transformer – the transformer works in the principle of electromagnetic induction
D. Superconducting Magnet – magnet made from coils of a superconducting wire
E. Relay – This electrical switch is operated by a magnet

To measure the strength of an earthquake, you can use either a _____ scale or _____ scale. does anyone have the choices or know the answer
Earthquakes are measured with the Richter Magnitude Scale developed by Charles F. Richter of California Institute of Technology in 1935. Here is a summary of the Richter scale:
Magnitude less than 3.5: Generally not felt, but recorded.
Magnitude 3.5-5.4: Often felt, but rarely causes damage.
Magnitude under 6.0: At most slight damage to well-designed buildings over small regions.
Magnitude 6.1-6.9: Can be destructive in areas up to 100 kilometers across where people live.
Magnitude 7.0-7.9: Major earthquake. Can cause serious damage over larger areas.
Magnitude 8 or greater: Great earthquake. Can cause serious damage in areas several hundred kilometers across.
Earthquakes are also measured by the Mercalli Intensity Scale which is a longer, more detailed scale. Both the Richter Scale and the Mercalli Scale can be seen on the U.S. Geological Survey website.
As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. Calculate the pressure exerted on the floor by the heel if it has an area of 1.64 cm2 and the woman's mass is 67.0 kg. Express the pressure in pascals. (In the early days of commercial flight, women were not allowed to wear high-heeled shoes because aircraft floors were too thin to withstand such large pressures.)
Area of heel
Mass of woman
Pressure is defined as Force applied in over an area such that it is perpendicular to it i.e.
What is a small particle of an atom carries a neutral charge?
The radius of an atom is closest in size to a
the radius of the entire atom was 0.00000001 cm.
From all the choices available in that question, it's closest in size to the dot over the ' i ' in the words "radius", "is" and "in".
