Answer:
a
b
Explanation:
From the question we are told that
The wavelength is 
The energy is 
This energy is mathematically represented as
Where c is the speed of light with a value 
h is the Planck's constant with the value 
n is the number of pulses
So
substituting values
Given that the pulses where emitted 20 times in one second then the period of the pulse is
Hence the average power of photons in one 80-mJ pulse during 1 s is mathematically represented as
substituting values
Answer:
Velocity is the speed of something given in a direction. the SI unit of velocity is metre per second or m/s.
The isotopes of a element is defined as the atoms having same atomic number and different mass number.
As per periodic table Br has atomic umber Z=35 and its atomic mass is given as 79.904 or 79.
As per the question nothing has been mentioned .
so all the atoms whose atomic number will correspond to 35 will be considered as the isotope of bromine.
Generally Bromine exhibits two isotopes which are stable.The isotopes are Bromine-81 and Bromine-77.
Some times during the process of gamma decay Bromine forms many radio isotopes also which are unstable.

Answer:
1100 Hz is a discriminitive stimulus signal (SD), while 1300 Hz is a discriminitive stimuli for extinction (S∆
)
Explanation:
This is used to describe Discrimination Training in learning and behavior. The 1100 Hz is a discriminitive stimulus signal (SD), while 1300 Hz is a discriminitive stimuli for extinction (S∆
)
