Answer:
Explained below
Explanation:
1) Liquid in glass thermometer: This type of thermometer is used primarily to measure the temperatures from inspection of changes in volume of liquid.
Thermometry substance is mercury or alcohol
2) Gas thermometer: This type is used to measure temperature as a result of changes in gas pressure or volume.
Thermometry substance is Gas.
3) Resistance thermometer: This type is used to measure temperature due to changes in electric resistance.
Thermometry substance is Resistance wire.
4) Thermocouple thermometer: This type is used to measure the temperature due to changes in electrical potential difference occurring between two metal junctions.
Thermometry substance is two wires that are dissimilar.
5) Bimetallic thermometer: This is a type of thermometer that measures temperature by converting temperature into mechanical displacement by making use of Bimetallic strip.
Thermometry substance is two metals that are dissimilar.

Neutral charge, because neutron means neutral
Answer:
<h2>760 m/s</h2>
Explanation:
The jet's speed or final velocity can be found by using the formula
<h3>v = u + at</h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question we have
v = 600 + 20(8)
= 600 + 160
We have the final answer as
<h3>760 m/s</h3>
Hope this helps you
