There should be a small amount of play in the wheel when the steering is locked. Gently pull the key from the ignition while you slowly jiggle the steering wheel back and forth. If this is the cause of the problem, the key should come out after a little effort.
==> Infrared waves from the sun, green light from the sun, and X-rays from the sun, all travel through vacuum.
==> Ocean surf waves travel through water.
==> Microwaves in an oven travel first through air, and then later through meatloaf or chicken.
==> Seismic waves (earthquakes) travel through rocks and dirt.
The term that is used to describe the energy needed to start a reaction is B. Activation Energy.
In this problem we are given with the speed of the signal and the distance travelled and is asked to determine the time of travel. IN this case, the expression that can be applied is
<span>time = distance / speed
= (3.6 × 10⁷ m) / (3 × 10⁸ m/s)
= (3.6 / 3) × 10⁷⁻⁸ s
= 1.2 × 10⁻¹ s
t= 0.12 s</span>
