Answer:
35
Explanation:
so you said 140 in total and it's a square
it's basically finding the perimeter of the square
so 35 is each side of the square that I am imagining in my head
so if you add 35...4 times you will get 140
for example:35
35
35
+ <u>3</u><u>5</u>
<u>1</u><u>4</u><u>0</u><u> </u>
or 35×4=140
Answer:
The answer is true.
Explanation:
Most of it is done in computer, but it can also be drawn out by hand.
Explanation:
Step1
Lehr is the long open or closed insulated space for glass manufacturing. Lehr must be large enough to keep the cooling of glass uniform. The function of Lehr is the same as an annealing process in metallurgy.
Step2
Lehr decrease the cooling and temperature variation in glass production. Uneven temperature creates the internal stress in the glass. Lehr reduces the internal stress in the glass product. So, the main purpose of the Lehr is to reduce the internal stress and keep the cooling uniform.
Answer: C
Both A and B are correct
Explanation:
Latent heat is the hidden heat.
Latent heat is the heat energy required to change one state of matter to another state of matter without change in temperature. For example, solid state to liquid state, or liquid state to gaseous state.
Thermometer can not detect the latent heat. That is why it is called hidden heat.
If Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. And Technician B says that latent heat is hidden heat that is required for a change of state of matter, then we can therefore conclude that both Technician A and Technician B are correct.
