A solid weighs 0.09N in air and0.02N in a liquid of density 700kg/m³.Calculate the Upthrust of liquid on the solid and volume of the solid

Explanation:

solid weighs in air = .09 N .

solid weighs in liquid = .02 N

solid weighs less due to upthrust acting on it upwards .

upthrust = .09 - .02 = .07 N

upthrust = weight of liquid displaced

so weight of liquid equal to volume of solid = .07 N

mass of liquid equal to volume of solid = .07 / 9.8 = .00714 = 7.14 x 10⁻³ kg

volume = mass / density

volume of solid = 7.14 x 10⁻³ / 700

= 1.02 x 10⁻⁵ kg

= 1.02 x 10⁻² g .

explanation:

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
