(20%) one hundred jumping beans are placed along the center line of a gymnasium floor at six-inch intervals. twelve hours later, the distance of each from the line are measured, and the sum of the squares of the distance divided by 100 is 36 in. 3, (1000) assuming only one-dimensional movement away from the line, calculate the diffusion coefficient of the jumping beans. (10%) if the mean jump distance of a bean is equal to 0.1 inches, estimate the mean jump frequency of a bean. a. b.

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
