Answer:
Convection and Radiation mechanisms carry most of the heat
Explanation:
This is because Convection proceeds strongy as heated air rises from the hot element while Radiation is also strong, although the material of the cooking pots will how effective it is.
Water hyacinth can fully cover lakes and wetlands, displacing native aquatic species, reducing fish oxygen levels, and providing optimal habitat for disease-carrying mosquitoes. Water hyacinth infestations can obstruct river transportation, fishing, damage bridges, and clog dams.
Answer:
he electron moves in the direction of a greater electric potential
Explanation:
Electric potential and electric field are related
V = -∫ E .ds
t
he electric force is related to the electric field
F = q E
F = q (-dV / ds)
since the electron has charge a = 1.6 1019 C
F = e dv / ds
therefore the electron moves in the direction of a greater electric potential
Answer:
contact
Explanation:
A contact force is defined as a force which requires some contact to occur. When we apply force that is in contact with the objects are called as contact forces.
In the context, Carmen is loading furniture and boxes on a moving van by picking up by picking up the boxes or furniture on a cart and pushing it onto the van. Carmen uses contact forces to lift the boxes and furniture onto the van.
Gravity - is the universal force that is effective over the longest distance.
