How many hydrogen bombs does Russia have?

User Avatar

Asked by Wiki User

I do not have accurate figures on the number of nuclear weapons in Russia's military stockpile. Nuclear armament is a sensitive topic, so most nations do not publicly disclose exact details about their nuclear arsenals.

What are the disadvantages of C-4 explosive?

User Avatar

Asked by Wiki User

Some disadvantages of C-4 explosive include its sensitivity to heat, friction, and impact, which makes it potentially dangerous to handle. It is also expensive to produce and requires specific expertise to handle and detonate safely. Additionally, C-4 can release toxic fumes when detonated, posing health risks to individuals nearby.

What means GPS and GIS?

User Avatar

Asked by Wiki User

GPS stands for Global Positioning System, a satellite navigation system that provides location and time information anywhere on Earth. GIS stands for Geographic Information System, a technology that captures, stores, analyzes, and displays geographic data, allowing users to visualize, interpret, and understand spatial relationships.

What aircraft are the strongest?

User Avatar

Asked by Wiki User

It is difficult to determine the strongest aircraft as strength can be measured in various ways such as payload capacity, speed, range, or maneuverability. Some of the aircraft considered strong in terms of firepower and technology are the Lockheed Martin F-22 Raptor, Boeing B-52 Stratofortress, and the Northrop Grumman B-2 Spirit.

Why does an atomic bomb release more energy than a conventional chemical bomb?

User Avatar

Asked by Wiki User

Atomic bombs rely on nuclear fission or fusion reactions, which involve the splitting or merging of atomic nuclei, leading to a much greater release of energy compared to the chemical reactions in conventional bombs. Nuclear reactions involve a much higher energy density per unit mass than chemical reactions, resulting in the powerful explosions associated with atomic bombs.

What is the most common use for caesium?

User Avatar

Asked by Wiki User

The most common use for caesium is in atomic clocks, where its highly predictable oscillation frequency is used to keep time with extreme accuracy. It is also used in the oil industry to analyze mud density and in some medical applications for cancer therapy.

How did 2 bullets lead to 20 million deaths?

User Avatar

Asked by Wiki User

The assassination of Archduke Franz Ferdinand of Austria-Hungary in 1914 was the catalyst for World War I, where over 20 million people were killed. The two bullets fired by Gavrilo Princip in Sarajevo set off a chain of events that escalated into a global conflict involving numerous countries and alliances.

Why do different elements give off different energy signals?

User Avatar

Asked by Wiki User

Different elements give off different energy signals because each element has a unique structure of electrons surrounding its nucleus. When these electrons transition between energy levels, they emit light or energy at specific wavelengths characteristic of that element. This is the basis for techniques like atomic emission spectroscopy that are used to identify elements based on their unique spectral signatures.

Did the atomic bomb create global warming?

User Avatar

Asked by Wiki User

No, the atomic bomb did not create global warming. Global warming is primarily caused by human activities that increase greenhouse gas emissions, which trap heat in the Earth's atmosphere. The atomic bomb explosions released large amounts of energy and radioactivity, but did not directly contribute to global warming.

The ingredients of the atomic bomb?

User Avatar

Asked by Wiki User

The main components of an atomic bomb are enriched uranium or plutonium as the fissile material, conventional explosives to create critical mass, and a trigger mechanism to initiate the nuclear reaction. These ingredients, when combined, result in a nuclear chain reaction leading to a massive release of energy.

Why did the Cambrian explosion may not have been an explosion?

User Avatar

Asked by Wiki User

The term "Cambrian explosion" is a bit misleading because the diversification of early metazoans actually occurred over tens of millions of years, rather than a sudden event. Some scientists prefer to refer to it as the "Cambrian radiation" to better capture the gradual nature of the process. This prolonged period of diversification resulted in the emergence of a wide range of complex multicellular organisms.

A modern day aircraft carrier weighs 100000 tons 1 cubic centimeter of neutron star stuff would weight as much as how many aircraft carriers?

User Avatar

Asked by Wiki User

A cubic centimeter of neutron star material would weigh approximately 400 million tons, which is equivalent to 4,000 aircraft carriers. Neutron stars are incredibly dense, with material packed tightly together due to the immense gravitational forces at play.

When electrons move from a high energy excited state to a low energy ground state. E Energy is absorbed by the atom?

User Avatar

Asked by Cdsa7205

No, energy is released by the atom when electrons move from a high energy excited state to a low energy ground state. This energy is emitted in the form of light or heat depending on the specific energy level transition. The difference in energy levels determines the wavelength of the light emitted.

Is the Philippines a part of the Pacific Islands?

User Avatar

Asked by Wiki User

Yes, the Philippines is considered part of the Pacific Islands region. Geographically, it is located in Southeast Asia in the western Pacific Ocean. The Philippines is often included in discussions about the Pacific Islands due to its proximity and shared cultural and historical connections with other Pacific Island nations.

What are the differences between low explosive and high explosive?

User Avatar

Asked by Wiki User

Low explosives deflagrate (burn) at a subsonic speed, while high explosives detonate at a supersonic speed, resulting in a shock wave. Low explosives are slower and less powerful, often used in fireworks and pyrotechnics, while high explosives are faster and more powerful, commonly used in military and mining applications.

What do spectral lines tell us about the internal structure of the atom?

User Avatar

Asked by Wiki User

Spectral lines provide information about an atom's energy levels and the transitions between them. By analyzing the pattern of spectral lines emitted or absorbed by an atom, we can determine the allowed energy states within its electron configuration, revealing insights into the atom’s internal structure and electron arrangement.

Does splitting wood involve splitting atoms?

User Avatar

Asked by Wiki User

No, splitting wood does not involve splitting atoms. Splitting wood refers to the process of using a tool, such as an axe or a log splitter, to separate a piece of wood into smaller pieces that are more manageable for fuel or woodworking purposes. Splitting atoms, on the other hand, refers to the process of breaking apart the nucleus of an atom, often done in nuclear reactions for energy production or scientific research.

What are atoms like in the inside?

User Avatar

Asked by Wiki User

At the center of an atom is the nucleus, which contains protons and neutrons. Protons have a positive charge and neutrons have no charge. Surrounding the nucleus are electrons, which have a negative charge. The electrons move around the nucleus in specific energy levels or orbits.
