During a spacewalk, an astronaut lets go of a tool, causing it to float away and bounce off the side of the space shuttle. The astronaut saw the the tool hit the shuttle but did not hear it hit the shuttle. Why would the astronaut be able to see the tool hit the shuttle but not hear it hit the shuttle? A.
Neither sound waves nor light waves can travel through a vacuum.

B.
Sound waves can not travel through a vacuum but light waves can.

C.
Both sound waves and light waves can travel through a vacuum.

D.
Light waves can not travel through a vacuum but sound waves can.

B mate

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.

no simpler subs form complex ones. synthesise = make
