Depends on the speed of the vehicle you are hitting with Actually it depends on the material components of the glass: how much silica, water, sodium carbonate, lead, boron, barium, cesium, iron, lanthanum, oxygen, thorium, sodium sulfate, sodium chloride, calcium, magnesium or antimony, how thick the glass is, how warm or cold the glass is, and how warm or cold is the environment.
Pretty much any element can be mixed into glass for different properties. Soda glass (SiO2, Na2CO3) is the most often used and created. A drinking glass of 3/8" thick and 4" around, 6" high can shatter from internal stress (temperature difference outside and inside causing shearing) in less than 0.1 seconds, so a minimum speed for this specific glass is:
distance (in miles): 6 in x 1 ft / 12 in x 1 mile / 5280 ft = 0.0000947 miles
time (in hours): 0.1 sec x 1 hr/3600 sec = 0.00002778 hrs
0.0000947 miles /0.00002778 hrs = 3.4 mph
seems pretty slow but most glass is not miles long. Decreasing the brittleness of the glass with doping agents (calcium etc) will decrease the speed of breakage as the glass will bend a little more and add stretching time to the breaking period, i.e. slow it.
What else can I help you with?
Why does sunshine break glass?
Sunshine does not break glass. It is not the sun's rays by themselves that break glass, but rather the heat they generate. When sunlight shines through a glass window, it can heat up one side of the glass unevenly, causing stress within the glass that may lead to cracking or breaking.
What is the difference in the speed of light in air, water, and glass?
The speed of light is fastest in air, slower in water, and slowest in glass.
What will be the speed of light in glass?
The speed of light in glass is slower than the speed of light in a vacuum, typically around 200,000 kilometers per second. This reduction in speed is due to the interaction of light with the atoms and molecules in the glass, causing it to bend or refract.
When transporting a glass top range does it have to be upright?
It is recommended to transport a glass top range upright to avoid damaging the glass or internal components. Placing it on its side or upside down can cause stress on the glass and may result in cracking or breakage during transportation.
Why does not a pyrex glass crack when hot water is poured on it?
Pyrex glass is made with a specific type of thermal treatment that makes it more resistant to thermal shock. This allows it to withstand sudden changes in temperature, such as pouring hot water on it, without cracking. Additionally, the chemical composition of Pyrex glass helps it to expand and contract more evenly when exposed to heat, reducing the likelihood of cracking.
How can you make a hole in glass without cracking it?
To make a hole in glass without cracking it, you can use a diamond-tipped drill bit or a high-speed rotary tool with a diamond burr. These tools are able to cut through the glass without causing it to shatter. It is important to use a steady hand and apply gentle pressure to avoid damaging the glass.
How can glass be heated without cracking it?
Glass can be heated without cracking by gradually increasing the temperature and allowing it to cool slowly to prevent thermal shock. This process helps the glass to expand and contract evenly, reducing the risk of cracking.
What is a sentence for cracking?
I hope you have a cracking time.The glass began cracking under the weight.Stop cracking your knuckles.
How can I safely put a hole in glass?
To safely put a hole in glass, you can use a glass drill bit and a drill with a variable speed setting. Make sure to wear safety goggles and gloves to protect yourself from glass shards. Start by marking the spot where you want the hole and then slowly drill into the glass using light pressure and a steady hand. Keep the glass surface wet with water to prevent overheating and cracking.
Can you drill holes in glass and if so, what is the best method to do so?
Yes, it is possible to drill holes in glass. The best method to do so is by using a diamond-tipped drill bit specifically designed for glass. It is important to use a lubricant, such as water, while drilling to prevent the glass from cracking. Additionally, drilling at a slow speed and with gentle pressure can help achieve a clean and precise hole in the glass.
Is hot glass cracking when placed in cold water a chemical or physical change?
Physical. The glass expands or contracts depending on temperature, when you put a hot glass into cold water part of the glass cools and contracts while some of it is still in it's hot, expanded state.
Is hot glass cracking when placed into cold water a chemical or physical change?
It is a physical change because the chemical composition of the glass does not change.
Where will be speed of light minimum-water or air or vacuum or glass?
The speed of light is minimum in Glass. It is because light travels at minimum speed in solids.
What are the best techniques for using glass drills effectively?
The best techniques for using glass drills effectively include using a lubricant to reduce friction, drilling at a slow speed with light pressure, and supporting the glass properly to prevent cracking. Additionally, using a diamond-tipped drill bit and wearing safety goggles are important for successful drilling.
How is a glass jar processed?
Food may be canned in glass jars or metal containers, insignificant scratches in glass may cause cracking and breakage while processing jars in a canner.
How do you effectively drill a hole in glass?
To effectively drill a hole in glass, you will need a specialized glass drill bit and a drill set to a low speed. Begin by marking the spot where you want the hole and securing the glass in place. Use a lubricant like water to keep the drill bit cool and prevent cracking. Apply gentle pressure and drill slowly to avoid shattering the glass. Clean the hole with a damp cloth once finished.
How does the speed of light that emerges from a pane of glass compare with the speed of light incident on the glass?
Those speeds are equal, even though the speed of the light was temporarily less while it was inside the glass.
