One shoe has a pointed heel that has a small cross sectional area, and another shoe has a broad heel with a large cross sectional area. both shoes have the same mass and are made of the same material. which shoe can cause more pain if the same person wearing it accidently uses their heel to step on another person's foot? and why?

the shoe which having heel of smaller crossection area.

Explanation:

Pressure is defined as the thrust acting per unit area.

Thrust is the force which acts on the surface perpendicularly.

Pressure = force / Area

Its SI unit is Pascal or Newton per square metre.

As both the shoes have same mass, so force is same but the area of crossection is different for both the shoes.

Teh shoe having heel of small crossection area exerts more pressure on another person's feet then the shoe having heel which has more crossection area.

Explanation:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
