What is buoyancy and how does it affect a blimp?

buoyancy is a measure of how well an object will float in a given medium, eg: a boat in water. similarly for a blimp, the blimp is the object, the air is the medium. if it is not buoyant enough, it will not 'float' in the air, aka fly

How do you make a mousetrap car pull weight?

if you mean "how do you make a mousetrap pull a car's weight" then you do it through pulleys. for example, if a mousetrap exerted 10N of force and a car needed 10000N to pull it, the pulley you use would need a distance input : distance output ratio of 1000:1 (aka if you pull one side 1000 meters, the other side moves 1 meter). this would enable you to move the car theoretically, but in reality, the distance the car moves would be so small that it would be useless, and even then, it is more likely for whatever rope/chain you are using to just stretch slightly.

What do you call a scientist that makes bombs?

For bombs such as atomic or nuclear, I believe it is a nuclear engineer.

How did the Incas use their natural resources?

The Incas utilized their natural resources for construction, agriculture, and crafts. They mined precious metals like gold and silver for ornamentation and currency, built intricate stone structures using quarried stones, terraced mountainsides for farming, and wove textiles from llama and alpaca wool. This utilization of natural resources played a crucial role in the Inca civilization's development and sustainability.

What is bounce in the internet?

Bounce can refer to a number of things. The two that came to mind when I saw the question are - a 'ping' test and an 'undelivered' email.

With a ping test. Your network providers mainframe computer sends a small data 'package' to your computer via the internet connection to calculate its speed. This package is then 'bounced' back to the ISP by your modem. The ISP computer then calculates how long it took to send and receive the data - this is quoted in milliseconds.

With undelivered email, the original message is 'bounced' back to the sender with a note saying it '...could not be delivered to all or some of the recipients....'

Do heterotrophs convert solar energy into chemical energy?

No, heterotrophs cannot convert solar energy into chemical energy. Heterotrophs obtain their energy by consuming other organisms or organic matter that have already converted solar energy into chemical energy through processes like photosynthesis.

Is fiberglass metal?

No, fiberglass is not metal. It is a composite material typically made of glass fibers embedded in resin. It is lightweight, durable, and commonly used in various applications such as insulation, boats, and car bodies.

What are energy vampires?

Energy vampires refer to people who drain others of their emotional or physical energy through their negativity, drama, or constant demands. This can leave the other person feeling drained or depleted after interacting with them. Setting boundaries and practicing self-care are important strategies for dealing with energy vampires.

How do you convert ms to seconds?

Multiply milliseconds by 1000 which will give u second. Simple explanation is that milliseconds is 1000th part of a second.

What are the properties of covalently bonded materials?

The attraction-to-repulsion stability that forms between atoms when they share electrons is known as covalent bonding.

In other words, a covalent bond is as follows : a bond sharing electrons between atoms. The protons and electrons keep the elements held together by sharing their electrons between atoms to ensure stability.

What the purpose of the stand fan?

The purpose of a stand fan is to provide a cooling breeze in a room or space. It helps to circulate air, creating airflow that can help make a room feel more comfortable by reducing heat and humidity. It is a portable and convenient way to improve ventilation and air circulation.

What makes a bome go off?

a bomb can go off in a number of ways. If it is a grenade, the fuse is lit by the pulling of the pin and ejection of the lever. When the spark reaches the ignitor, a tiny explosion is produced that causes a chain reaction with the gunpowder in the grenade. For one of those bombs with the "Which one should I cut? Red or Blue" wires, I'm not quite sure.

Does a heavier object always have more inertia than a lighter object?

Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.

Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.

So assuming they are turning at the same angular velocity, the heavier one has a larger inertia. Otherwise, remember that inertia is also proportional to angular velocity.

How do you unlock silver in Super Smash Flash?

In Super Smash Flash, silver can be unlocked by completing Classic Mode with 5 different characters. This will trigger the appearance of a challenger named Silver. Defeat Silver in order to unlock him as a playable character.

When is aluminum a liquid?

The scientific standard typically refers to the state change you refer to in terms of going up, so you need to know the melting point of aluminum to know when it becomes solid, which is 933.47 Kelvin (660.32°C or 1220.58°F).

So anything above the melting point would be a liquid.

And anything below the melting point would be a solid.

What are the three elements of electricity?

The three basic elements of electricity are voltage, current, and resistance. Voltage is the force or pressure that drives the electrical current. Current is the flow of electric charge. Resistance is the opposition to the flow of electric current.

How is a serial number assigned to a part?

A serial number is typically assigned to a part during the manufacturing process. It can be created based on a specific algorithm, sequentially, or randomly generated. This unique identifier helps to track individual parts, monitor quality control, and trace the product throughout its lifecycle.

What are all the differences between active and passive transport?

Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own.

Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way!

Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell.

Active transport requires energy, but passive transport requires none.

Active transport requires a special protein to make the transport occur, but passive transport requires none.

Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?

Adaptive optics technology can enable ground-based telescopes to achieve images as sharp as those from the Hubble Space Telescope. This technology involves using mirrors that can change shape to compensate for the distortions caused by Earth's atmosphere, allowing for clearer and more detailed images.

What technology did Gregor Mendel use for his pea plant experiments?

Gregor Mendel used traditional manual methods such as cross-pollination and careful record-keeping for his pea plant experiments. He observed the patterns of inheritance by systematically breeding pea plants with specific traits over multiple generations. Mendel's experiments laid the foundation for modern genetics.
