<span>All of the following were barriers to minority participation in early psychology except school desegregation. The correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that you were looking for and the answer has come to your great help.</span>
Explanation:
According to the energy conservation,



= 
= 
v = 
= 
Formula for distance from the orbit is as follows.
S = 
= 
= 
Now, relation between time and distance is as follows.
T = 

or, f =
=
= 
Thus, we can conclude that the orbital frequency for an electron and a positron that is 1.50 apart is
.

Answer:
work done = 500 J
option e is correct
Explanation:
given data
mass = 2 kg
acceleration = 2 m/s
coefficient of kinetic friction = 0.3
block D = 50 m
to find out
work
solution
we know that work done is
work done = f × d ...........1
here f is force and d is block i.e 50 m
so here
force , f - k mg =ma
f = 2 ( 2 + 0.3 ×10 )
f = 10 N
so from equation 1
work done = f × d
work done = 10 × 50
work done = 500 J
option e is correct
i dont understand wat ur tryna say ma dude but whatever it is its.............PIZZA
