The work done is 137 joules.
Lifting opposes the acceleration of gravity, which is 9.8 m/sec/sec.
20 x 0.7 x 9.8 = 137 J (kg-m2/sec2)
Answer:
option D is incorrect
Explanation:
the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.
ANSWER: Genes
Genes hold an organisms hereditary information.
Answer:
all plant cell have primary cell wall .it is thin and occurs outside of the cell membrane. it mainly consists of cellulose fibres that that can stretch the cell to grow .
Stress is the force applied to a rock, which may cause deformation. The three main types of stress go along with the three types of plate boundaries: compression is common at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries.
