The relationship between electricity and magnetism is called<span> electromagnetism.</span>
The impact speed will be
v^2 = 2*9.8*1.3
v^2 = 25.48
v= 5.04 m/s
Answer:
option A is correct
Explanation:
acceleration the time rate of change of velocity or speed so
a=Δv/t
Δv=vf-vi
Δv= final speed-initial speed
now a=final speed-initial speed/time
Answer:
a) 
b) 
Explanation:
From the question we are told that:
Width of diffraction grating 
Width of silt 
Distance 
a)
Generally the grafting element is the distance b/w the silts

Therefore the grafting element is

b)
Generally the equation for diffraction state is mathematically given by

Since

Therefore



Therefore orders observed with
is
