find a chisel. describe why it is a wedge and how it works.

A chisel is a type of machine called a wedge.

Explanation: A wedge is a simple machine that consists of two inclined planes, giving it a thin end and thick end.

Force is applied to the thick end of the wedge, and the sloping sides of the wedge apply force to the object, cutting/splitting it apart.

A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance.

Other example of wedge is a hammer

answer; ///(74) degrees is your answer..

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.
