If a 79.6 kg dancer stands on one toe, what is the magnitude of pressure exerted on that toe to support his weight?

(Magnitude only! No negative numbers)

*Assume that tip of the dancer's toe has a radius of 0.02 m and has a circular area of contact.

Area of a circle= pi r squared

Karen is running forward at a speed of 9 m/s. she tosses her sweaty headband backward at a speed of 20 m/s. the speed of the headband, to the nearest whole number relative to a stationary observer watching karen

Which one of the following research methods can show cause and effect

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
