i THINK question 18 is (b) and 19 are (A)
Glass is the material that would provide the most electrical resistance.
Elements which are good conductors of electricity are referred to as
Metals. They usually have low resistance.
<h3> Examples of Metals</h3>
Non metals are are low conductors of electricity and have high resistance.
Electrolytes such as salt water are also good conductors of electricity.
Glass are generally regarded as Insulators and are poor conductors of
electricity which makes it the material with the most electrical resistance.

Answer:
I feel like its the second one but I'm not completely sure..
Explanation:
To develop this problem we will apply the concepts related to the Doppler effect. The frequency of sound perceive by observer changes from source emitting the sound. The frequency received by observer is more than the frequency emitted by the source. The expression to find the frequency received by the person is,
= Frequency of the source
= Speed of sound
= Speed of source
The velocity of the ambulance is
Replacing at the expression to frequency of observer we have,
Therefore the frequency receive by observer is 878Hz
