masha68 [24]3 years ago
3 0

Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy.

Kruka [31]

Answer:

more than 90%

Explanation:

In the unknown liquid the buoyant force and weight relation is

V\rho_lg=mg\\\Rightarrow V\rho_l=m

It can be seen that if the density decreases the buoyant force decreases.

If the object is already 90% submerged in water then, if the other liquid has density less than that of water the object will be submerged more than 90%.

When water vapor rises into the atmosphere and begins to condense, it releases ________, the energy of a thunderstorm.
zubka84 [21]
The answer is latent heat. The specific latent heat of vaporisation, L_v, of a substance is the energy input required for each kilogram to be converted from liquid to gas by evaporation. The 'specific' means per kilogram, so more generally latent heat of vaporisation is the energy taken in during the process for a given mass.

Here we are not vaporising the substance. We are in fact condensing it, the reverse process. All this means is the latent heat is released as electrostatic potential decreases in the water, as opposed to being absorbed. I hope this helps you :)
