7 0

Answer:

A. 29.4 Joules

Explanation:

Given parameters:

Mass of the book  = 1.5kg

Height of lift = 2m

Unknown:

Potential energy acquired  = ?

Solution:

Potential energy is the energy due to the position of a body.

Mathematically;

       Potential energy  = mgh

m is the mass of the body

g is the acceleration due to gravity = 9.8m/s²

h is the height

     Potential energy  = 1.5 x 9.8 x 2

     Potential energy  = 29.4J

How do convection currents help form underwater mountains?
pogonyaev

The convection currents are the ones that create the force that breaks up and moves the crustal plates on the surface of the planet. By moving the crustal plates, the convection currents contribute to the formation of different types of plate boundaries, including the divergent plate boundaries.

The divergent plate boundaries are the boundaries where two plates are moving away from one another because the convection currents are dictating that kind of movement from bellow them. As they move away from each other, they leave a gap between them, and the convection currents push up a lot of magma towards the surface. The magma cools of very quickly in the water, thus forming rocks constantly, rocks that little by little start to make a big mas, that eventually turns into an underwater mountain, or rather a mid-ocean ridge.

Explain the relationship between evaporation, condensation, condensation
dmitriy555 [2]

There is a close relationship between evaporation( transformation of water into water vapor in presence of heat), condensation (transformation of water vapor into water droplets), condensation nuclei (minute water droplet) and cloud (assemblage of too many water droplets). For the formation of cloud all these mentioned conditions are required.

Explanation:

Evaporation refers to the transformation of water into water vapor by the action of heat, condensation means transformation of water vapor into water droplet in normal temperature, condensation nuclei refers to the water droplets which is base of formation of cloud.

Cloud forms from the assemblage of water droplets. These water droplets are formed in saturated air condition when the air is full of humidity. Relative humidity means the ratio between the water holding capacity of air and the amount of actual water in air at that particular temperature.
