Green houses gases like CO2, water vapour and methane, these gases traps heat in its structure, this is same like glass house in which infrared waves can only enter but after entering the waves will become polarisezed it will prevent waves going out and hence increrasing the temperature
The sudden change in pressure when water vapor is released causes cavities inside the popcorn to vibrate and produce sound, the researchers suggest—much like a champagne bottle's pop when uncorked. The scientists also discovered the mechanism for the kernel's acrobatic hop into the air. Hope this helps! ~ Autumn :)
Gravity causes falling objects to accelerate.
Answer:
Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged.
Explanation:
Answer:
2.5
Explanation:
The capacitance of a parallel-plate capacitor filled with dielectric is given by
where
k is the dielectric constant
is the capacitance of the capacitor without dielectric
In this problem,
is the capacitance of the capacitor in air
is the capacitance with the dielectric inserted
Solving the equation for k, we find
