The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.

Arrange the events in the life cycle of mosses in the flowchart below. Start the life cycle with the mature sporophyte stage in
labwork [276]

Answer:

Life cycle of a moss

Explanation:

LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE

An embryo further develops into a pear-shaped  sporangium, which is the *sporophyte  stage of the plant*. The sporangium  contains spore sacs, each of which is the spore mother cell that undergoes meiotic division  to form four spores,The spores are released and germination

takes  place giving  rise to a protonema, which develops into a new gametophyte plant. The gametophyte  generation or haploid phase of the moss is from the production  of haploid spores after meiosis  to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid  phase is from the diploid  mother cells just before meiosis.

Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.

The distance between two charges and is r, and the force between them is F. What is the force between them if the distance betwe
dimulka [17.4K]

The force between them if the distance between them is doubled is a. F/4

Explanation:

  • To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
  • The equation can be written as, F= K \frac{ q_{1} q_{2} }{r^{2} } where k is the Coulomb constant, q_{1}  q_{2} are the point charges, and r is the distance between these two point charges.
  • To find the answer to this question, just substitute 2r in the place of r hence, you will get \frac{F}{4} as the new force when the distance is doubled.
