An Olympic athlete set a world record of 9.26s in the -m dash. Did his speed ever exceed during the race? Explain.

yes

Explanation:

The question is not complete, a similar question is:

An Olympic athlete set a world record of 9.12s in the 100 m dash. Did his speed ever exceed 39 km/hr during the race? Explain?

Average speed is the ratio of total distance to total time.

The total distance = 100 m = 0.1 km, total time = 9.12 s = 0.00253 hr

Average speed = total distance/ total time = 0.1 km / 0.00253 hr = 39.37 km/hr

The Mean Value Theorem says that there is a point c between the range (a,b) at which the function's instantaneous rate of change is is equal to average rate of change.

Therefore there is a point at which the speed reaches 39.47 km/hr (exceed 39 km/hr) during the race.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
