Why is the laptop a good invention?
Laptops are a good invention because they are portable, allowing users to work or browse the internet from anywhere. They are also versatile and can be used for a variety of tasks such as work, gaming, or entertainment. Additionally, laptops have evolved to be powerful enough to handle most computing needs and have become an essential tool for many people in the modern world.
What happen if dented ping pong ball you put in ice water?
If you put a dented ping pong ball in ice water, the cold temperature may cause the air inside the ball to contract, intensifying the dent. Additionally, the change in temperature can affect the elasticity of the ping pong ball material, potentially making the dent more permanent.
Can bees see ultraviolet light?
Yes, which is how bees can navigate (using the sun as a reference) even on a cloudy day, because ultraviolet light passes through clouds. Just as we see the sun in a blue sky background on a clear day, the bee sees the sun in an ultraviolet sky background on even a cloudy day. The underlying reason that the sky appears ultraviolet to a bee (and blue to us) is that something happens to the sun's rays when they hit charged particles. These charged particles are in the ionosphere and in Nitrogen and Oxygen "dipoles" in the atmosphere. The sun's radiation will cause the charged particle to vibrate, and when the charged particle vibrates it re-radiates energy. If you work out the mathematics (physics) of this re-radiation, it turns out that the energy is re-radiated in proportion to the fourth power of the frequency (as discovered by Raleigh in the 1800's and worked out with a more accurate distribution formula by Einstein early in the 20th century). For humans, who have eyes that have blue, yellow and red sensors, the fourth power formula means that blue from the sky is ten times stronger than red, so the sky looks blue. Similarly, for bees (and other insects), the highest frequency sensors in their eyes detect ultraviolet), and so the sky appears ultraviolet to them. Sources: Karl von Frisch on Bees (e.g. in Answers.com); basic courses on electrodynamics and magnetism (or Google "Why is the sky blue").
What is the scientific names of a Burning bush leaf?
This stinks I need to know this cause its my homework
Is the hookworm a parasire?
Yes, the hookworm is a parasitic nematode that infects the small intestine of humans and other mammals. It feeds on blood and can cause health issues such as anemia and malnutrition.
Can objects be charged by friction and streching?
Yes, objects can be charged by friction through the transfer of electrons between materials. Stretching certain materials can also cause them to become charged due to the separation and movement of charges within the material.
How is an object charged by friction?
When two objects rub against each other, the transfer of electrons between the materials can cause one object to become positively charged (loss of electrons) and the other negatively charged (gain of electrons). This charging by friction is a result of the triboelectric effect.
Is a balloon negatively charged?
A balloon can become negatively charged when rubbed against certain materials, such as wool or fur. The friction created during the rubbing process can cause the balloon to gain extra electrons, giving it a negative charge.
Why does a friction cause a charge to develop?
When an object such as a balloon is charged by friction, it is because electrons are rubbed off of one object onto another. The electrons only change their location, otherwise they remain the same.
Can an object get charged from stretching?
No, stretching an object will not cause it to become electrically charged. Charging an object requires the transfer of electrons. Stretching changes the shape or size of an object but does not result in the accumulation of electric charge.
How do charges cause static electricity?
Charges cause static electricity through friction. When two objects rub against each other, electrons can transfer from one object to the other, causing one object to become positively charged and the other negatively charged. This build-up of charge creates static electricity.
Do two indentical objects become statically charged when you rub them together Explain why they do or do not?
Yes, when two identical objects are rubbed together, they can become statically charged due to the transfer of electrons between them. Friction between the objects can cause electrons to move from one object to the other, leading to a build-up of charge on each object.
Explain how a moving car can become positively active?
A moving car can become positively charged through processes like friction, which can cause the transfer of electrons between the car and another object. For example, when the car drives on the road, friction between the tires and the ground can result in the car gaining a positive charge if electrons are transferred from the road to the car.
How may cleaning a mirror actually cause it to become more dusty?
because of the friction
What is the role of friction in creating a charged object?
When two materials come into contact and rub against each other, friction can cause the transfer of electrons from one material to the other, creating a charge imbalance. This charge separation is what leads to the creation of a charged object.
What types of weather cause friction on surfaces to increase?
Wet or icy conditions can cause surfaces to become more slippery, increasing friction between objects. Additionally, strong winds or storm conditions can generate forces that increase the friction on surfaces.
How can an atom become positively or negatively charged by gaining or losing this subatomic particle?
An atom can become positively charged by losing an electron, resulting in more protons than electrons. Conversely, an atom can become negatively charged by gaining an electron, which creates an excess of electrons compared to protons.
