A student rides a bicycle in a circle at a constant speed and constant radius. A force diagram for the student-bicycle system is shown in the figure above. The value for each force is shown in the figure. What is the acceleration of the student-bicycle systern? a.0m/s^2

b. 0.2 m/s^2

c. 5 m/s^2

d. 25 m/s^2

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

e/c, where e is its total energy

according to jean piaget, in what stage of cognitive development are children able to understand conservation task?

b. preoperational

just took it

the ima (higher than 1m) will be greater than the ima with the height of 1m.
