Will give brainliest and 60 points!
which are properties of solids? check all that apply.

a. can change shape to conform to a container
b. has a rigid shape that does not change easily
c. is made up of free-moving ions and electrons
d. is compressed more easily than other states
e. has particles that can wiggle but cannot move
f. has particles that have some freedom to move
g. will expand to completely fill a closed container

Based on the list above the correct properties of solids are; 

B) has a rigid shape that does not change easily

E) has particles that can wiggle but cannot move

Solids have a variety of properties that make them different from liquids and gasses. Their particles are fixed making them rigid and hard to change shape. The particles also have a low kinetic energy making it hard for the particles to vibrate. In addition to those properties, solids cannot be compressed into smaller sizes.

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.
