Microwave ovens heat food through the process of A) COnduction B) Convection C) Radiation D)Stratification

Explanation:

In microwave, there are waves called "microwaves" as per the name. So, The heating of food is done with the help of waves. Radiation is "the transfer of heat through waves". That is why the process of heating food in a microwave is "Radiation".

Explanation:

Microwaves heat food through the form of waves.

The waves are electromagnetic waves that transfer heat through the process of radiation.

the average speed is 24.57 km/hr

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
