Which of the following is evidence that supports the big bang theory? A. Light from other galaxies sometimes takes thousands of years to
reach Earth, which shows that the galaxies are moving away from
Earth.
B. Light from other galaxies shows that light elements formed before
heavier elements.
C. Light from other galaxies always travels at the same speed, which
shows that the galaxies are moving away from Earth.
D. Light from other galaxies appears shifted toward the red end of
the spectrum, which shows that the galaxies are moving away
from Earth

D

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.

explanation:

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
