Answer:
A force of μk⋅60N is needed to keep a 60-newton rubber block moving across level, dry asphalt in a straight line at a constant speed.
Explanation:
Answer:
The comparison of unknown quantity with known quantity is called measurement.
I believe that it is d correct me if wrong because the higher the temperature the more active the molecules are gonna be, but the graph does not explicitly state that, so you can say the answer is d (if not the answer is c) (sorry if wrong)
A thermogram is a representation of infrared electromagnetic waves better known as heat waves. So the correct answer is infrared electromagnetic waves or infrared waves.
Explanation:
The thermogram is associated with infrared camera creates a picture by changing effulgent heat into a symbol which will be displayed on a monitor (and later printed). The infrared energy emitted from the associated object is directly proportional to its temperature. Thus it can be used for temperatures that are accurately measured by the infrared camera.
