Explanation:
First of all we calculate the volume which is 20m×10m×8m= 1600m^3 and then multiply the density by the volume to get the mass which will equal to 99200kg therefore the weight will be
<em><u>Weight</u></em>
mass × acceleration due to gravity
=99200kg × 10m^s^2
=992000N
A . Thermal
Thermal Energy, or heat, is the internal energy in substance the vibration & movement of the atoms & molecules within substances. Geothermal energy is an example of thermal energy.
Answer:
Diffusion requires energy only to move material through the cell membrane.
Explanation:
:)
Because the molecules that move freely begin to compact closer together, with less heat, means less molecular activity.
Mercury is very harmful to the average human being. the mercury can easily be released from the lamp if the lamp is knocked over and broken. mercury is also harmful if inhaled. sodium on the other hand is not harmful in any way.
