Answer:
Part a)
Part b)
Explanation:
As we know that electric force on electric charge is given as
here we have
E = 153 N/C
now force is given as
Gravitational force on electric charge near surface of earth is given as
now the ratio of two forces is given as
Part b)
Now the ball is balanced by the electric force and the force of gravity on it
so here we have
here we have
Percent error is calculated as follows:
% = ( |15-15.6| / 15.6 ) * 100%
% = (0.6/15.6) * 100%
% = 0.0385 * 100%
% = 3.85%
Hope this helped!
Answer:
Explanation:
given,
s = 400- 16 t²
we know,
Velocity of an object is defined as the change in displacement per unit change in time.
velocity an also be return as
Hence, instantaneous velocity function given by
To calculate instantaneous velocity, you need to insert value of time.
ex, instantaneous velocity at t = 4 s
v = -32 x 4 = -128 m/s.
Rate of speed (3 m/s north is three miles per second north, so it's a rate of speed)
So my opinion that is false bc. the psychological profiling not is necessary being as criminal profiling ,the criminal mean a greater,intensive word in the way of ,,killer" ,when the ,,psychological" profile is total different way
