Will moving water freeze in pipes?
Yes, moving water can freeze in pipes if the temperature drops low enough and the water flow is slow or stops completely.
Yes, moving water can freeze if the temperature drops low enough.
Will my room smell if I smoke out the window?
Yes, smoking out the window may still leave a lingering smell in your room, as smoke can easily seep back inside. It's best to smoke outside to prevent the smell from lingering indoors.
Will pairs of electrons attract or repel each other?
Pairs of electrons will repel each other due to their negative charges.
Will space time be flat if the universe continues to expand at an accelerating rate?
As the universe continues to expand at an accelerating rate, space-time is expected to remain flat according to current scientific theories.
Will a Faraday cage protect electronic devices from an EMP (Electromagnetic Pulse) attack?
Yes, a Faraday cage can protect electronic devices from an EMP attack by blocking the electromagnetic waves that could damage the devices.
Will a Faraday cage protect electronic devices from an electromagnetic pulse (EMP)?
Yes, a Faraday cage can protect electronic devices from an electromagnetic pulse (EMP) by blocking the electromagnetic radiation that could potentially damage the devices.
Will a bad water heater element use more electricity than a functioning one?
Yes, a bad water heater element will use more electricity than a functioning one because it will have to work harder to heat the water, leading to increased energy consumption.
Will a device designed for 110v work on 220v?
No, a device designed for 110v will not work on 220v without a voltage converter.
Will a hoop or disk roll faster?
A hoop will roll faster than a disk due to its larger radius and distribution of mass.
Will a running hose freeze if left outside in cold temperatures?
Yes, a running hose can freeze if left outside in cold temperatures because the water inside the hose can freeze due to the low temperatures.
Will aluminum foil burn in the oven?
Yes, aluminum foil can burn in the oven if it comes into direct contact with a heating element or if it is exposed to extremely high temperatures. It is recommended to use aluminum foil properly and follow safety guidelines when cooking with it in the oven.
Will an asteroid hit Earth in 2022?
There are currently no known asteroids on a collision course with Earth in 2022.
Why would an atomic nucleus give off a particle?
An atomic nucleus gives off a particle to become more stable and reach a lower energy state. This process is known as radioactive decay.
Yellowing of the eyes, known as jaundice, can be caused by a buildup of bilirubin in the blood. This can occur due to liver problems, such as hepatitis or cirrhosis, or other medical conditions affecting the liver or bile ducts. It can also be a sign of certain blood disorders or infections. If the eyes appear yellow, it is important to seek medical attention to determine the underlying cause.
Why would it be more difficult to start pedaling a bicycle with a 10,000 pound weight on it?
It would be more difficult to start pedaling a bicycle with a 10,000 pound weight on it because the added weight increases the resistance against the pedals, requiring more force and effort to overcome the inertia and get the bike moving.
Why would there be only one ocean tide per 24-hour day if the Earth did not rotate on its axis?
If the Earth did not rotate on its axis, there would only be one ocean tide per 24-hour day because tides are primarily caused by the gravitational pull of the moon and the sun. Without the Earth's rotation, the gravitational forces would create a single tide cycle in a 24-hour period.
Why, if everything is made of atoms, doesn't everything look the same?
Although everything is made of atoms, the way atoms are arranged and interact with each other determines the appearance of different objects. The unique arrangement of atoms in each substance gives them their distinct properties and characteristics, resulting in the variety of appearances we see in the world around us.
Why, if half of the moon is always dark, do we not always experience a new moon?
The phases of the moon are determined by its position relative to the Earth and the Sun. Even though half of the moon is always dark, we do not always experience a new moon because the angle at which we see the illuminated portion of the moon changes as it orbits the Earth. This causes different portions of the illuminated side to be visible from Earth, resulting in the various phases of the moon.
Why, if the sun is a "green star," does it not appear green in the daytime sky?
The sun is not actually a green star; it is classified as a yellow dwarf star. The perception of the sun as white or yellow in the sky is due to its light being a combination of different colors, which appear white when mixed together. The Earth's atmosphere scatters the sunlight, making it appear white to us.
Will a Faraday bag protect against an EMP?
Yes, a Faraday bag can protect against an EMP (Electromagnetic Pulse) by blocking the electromagnetic radiation that can damage electronic devices.
Will a Faraday cage block an EMP?
Yes, a Faraday cage can block an EMP (Electromagnetic Pulse) by redirecting the electromagnetic energy around the enclosed space, protecting the contents inside from the damaging effects of the pulse.
Why was the Expanding Earth theory rejected by the scientific community?
The Expanding Earth theory was rejected by the scientific community because it lacked substantial evidence and could not explain key geological phenomena, such as the movement of tectonic plates and the distribution of fossils across continents. Additionally, the theory did not align with established principles of plate tectonics and the understanding of Earth's structure and composition.
