How anti balistic missiles work?

User Avatar

Asked by Wiki User

Anti-ballistic missiles work by detecting and tracking ballistic missile threats, launching an interceptor missile to intercept and destroy the incoming missile warhead before it reaches its target. The interceptor missile uses various technologies such as radar, infrared sensors, and onboard guidance systems to accurately track and intercept the incoming threat. Upon successful interception, the warhead is destroyed through impact, fragmentation, or other specialized methods to neutralize the threat.

How stinguisher powder produce?

User Avatar

Asked by Wiki User

Fire extinguisher powder is typically made from materials like sodium bicarbonate or ammonium phosphate that are finely ground and mixed together. When the powder is released from the extinguisher, it works by smothering the fire, interrupting the chemical reaction that sustains it. The powder particles form a blanket over the fire, cutting off its oxygen supply and cooling the fuel.

Why gas doesn't leakes from holes in the bottom of lp gas stoves?

User Avatar

Asked by Wiki User

Gas stoves are designed with a safety valve called a thermocouple that shuts off the gas supply if the flame goes out due to a leak. The pressure of the gas inside the stove is also carefully regulated to prevent leaks from small holes. Additionally, LP gas is heavier than air, so it tends to sink rather than rise out of holes at the bottom of the stove.

Why is petrol insoluble?

User Avatar

Asked by Wiki User

How do you make red transparent glass?

User Avatar

Asked by Wiki User

To make red transparent glass, you would need to add a red colorant, such as copper oxide or selenium, to the glass mixture before melting and shaping it. The intensity of the red color can be adjusted by varying the amount of colorant added. Transparent glass can be made by controlling the cooling process during the glassmaking to minimize the formation of bubbles or imperfections.
