Answer:
<h2>
False </h2>
Explanation:
They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance. Infrared thermometers are a subset of devices known as "thermal radiation thermometers".
Since the greatest number in the given electron configuration of the atom is 4, it means that the element is found in the fourth energy level. The number of electrons found in the valence shell is 2+10+6 = 18. From this answer and using the periodic table, we can see that the atom is that of Krypton (Kr).
Answer:
Use the potential energy formula
Explanation:
PE=mgh
m=mass=2kg
g=gravitational force=-10
h=height=10m
Answer:
Please look in the explanation section
Explanation:
If the beam is in a magnetic field, a simple check is to rotate the CRT a quarter of a turn. If the beam is to the right, a magnetic field should be produced. This is because a magnetic field would be up or down that will allow the beam to be pushed to the right or left. In conclusion, if turning the CRT a quarter of a turn, nothing should happen because the CRT is perpendicular to the magnetic field.
A check to see if the beam is in an E field, you should rotate the CRT a quarter of a turn and see if the beam is centered. If you turn the CRT again another quarter of a turn and see if the beam is bent in the opposite direction. If both tests are true, then the CRT must be in an E field. Otherwise, the CRT will be broken.
