54-(15x2) divided by 2 = 12
54 - 15 = 39
39-15=24
24 divided by 2=12
Length:15

The Earth's mantle consistency is like melting wax.
Explanation:
Answer:
TRANSMISSION-
visible light meets clear glass
-cell phone signals pass through walls-
Explanation:
Transmission means that light actually passes through an object. Light in this context refers to electromagnetic radiation. All the radiation found in the electromagnetic spectrum are generally called light. This includes radio waves used in telecommunication.
White light is transmitted through glass because it actually passes through the glass.
Passage of cell phone signals through walls is also a typical example of transmission of light.
Answer:
While Hubble provides views of deep space, it doesn't magnify distant stars, alien planets and galaxies. Instead, it collects more light than the human eye can see on its own. With a telescope, the bigger the mirror, the better the vision.

The speed of the wave created by Linh in the spring by moving the other end right and left with a frequency of 2 Hz is 1m/s.
<h3>How to calculate speed of a wave?</h3>
The speed of a wave can be calculated by using the following formula:
Speed = Wavelength x Frequency
According to this question, Linh creates waves in the spring by moving the other end right and left with a frequency of 2 Hz. If wave crests are 0.5 m apart, the speed can be calculated as follows:
speed = 2Hz × 0.5m
speed = 1m/s
Therefore, the speed of the wave created by Linh in the spring by moving the other end right and left with a frequency of 2 Hz is 1m/s.
