Answer:
From electrical energy to radiation
Explanation:
A light bulb converts electrical energy to light, which is nothing more than radiation. Don't regard radiation as a bad thing, this light is non-iodizing radiation, which does not have the possibility to alter our DNA, and thus it's safe.
The simplest example can be found in old lights (obsolete now because they are vastly inefficient). This lights were just resistors which turned electrical energy into heat. A very hot material reflects light in the form of radiation, as described above.
Technologies like LEDs are more complicated to explain.
On the position time curve, if the slope of a tangent at a point is positive, that means:
A: The object is moving backward
B: The object is not moving
C: The object is moving forward
Answer:
C. the object is moving forward
Explanation:
A positive slope means position is increasing when time is increasing. Generally, increasing position is "moving forward."
Answer:
C. The object is moving forward

In a certain week, a production schedule for a certain department shows the following parts being produced: 540 parts of type A, 1200 parts of type B, 490 parts of type C, and 780 parts of type D. The respective production times for these parts are the following: TpA = 5.28 min, TpB = 2.86 min, TpC = 4.65 min, and TpD = 3.22 min. Determine the workload for this department in hours per week.
Answer:
about 185 hours per week
Explanation:
It is convenient to let a spreadsheet form the sum of products. The total is in minutes, so needs to be divided by 60 to get hours.
About 185 hours per week are required for the given production schedule.
