In SI units with dry air at 20*C (68*F), the speed of sound c is 343 meters per second (m/s).
The answers is 343 meters per second:
Answer:
100 micro-ampere
Explanation:
The sensitivity of an ammeter is the current required for the ammeter to reach its maximum reading or to cause maximum deflection of the ammeter.
As the relative amount of current required to cause maximum deflection of an ammeter is lesser, the sensitivity of the ammeter is said to be higher or the ammeter is said to be more sensitive
Therefore, given that the maximum reading on the given microammeter is 100 μA, the current required to cause the maximum deflection an thus the sensitivity of the ammeter is 100 micro-ampere.
Answer: True
Explanation:
Atomic number is defined as the number of protons or the number of electrons that are present in an electrically neutral atom.
Atomic number = Number of protons = number of electrons = 2
Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.
The electronic configuration will be
As its duplet is already complete and it has noble gas configuration , it is stable with 2 valence electrons.
The time of flight of
the dart is 36.761 s, it can be used to solve the initial velocity of the dart
bt the formula t= 2v/g, which v is equal to 180.31 m/s which is actually very
fast. We can now solve the maximum distanc H= v^2/2g which is equal to 1657.11
m.
