Sublimation is a type of printing that involves heat and a special type of printer. You use specialized ink to print onto transfer paper then place the paper on the item you are sublimating and then you heat press it for the allotted time.
Answer:
35 mph
Explanation:
From the question given above, the following data were obtained:
Time (t) = 2 hours
Distance (d) = 70 miles
Speed (S) =.?
Speed is simply defined as the distance travelled per unit time. Mathematically, it is expressed as:
Speed (S) = Distance (d) / Time (t)
S = d/t
With the above formula, we can calculate how fast (i.e the speed) Joe will need to drive to make it to his Grandma's house on time. This can be obtained as follow:
Time (t) = 2 hours
Distance (d) = 70 miles
Speed (S) =.?
S = d/t
S = 70/2
S = 35 mph
Therefore, Joe will drive at 35 mph in order to get to his Grandma's house on time.
Light ... and all other forms of electromagnetic radiation ... behaves
as if it were a stream of 'packets' that we call 'photons', each one
carrying a specific amount of energy.
Light ... and all other forms of electromagnetic radiation ... is
characterized by its wavelength. That is, once you state its wavelength,
you've stated everything there is to know about the light, including its
frequency, and the energy carried by each photon.
The name of the compound NaS is sodium sulfide.
