We're so good here on Brainly, we can answer it
even WITHOUT seeing the choices.
Time = (displacement) / (magnitude of average velocity) .
To get a uniform field in the central region between the coils, current flows in the same direction in each.
Index fossils (also known as guide
fossils, indicator fossils or zone
fossils) are fossils used to define
and identify geologic periods (or
faunal stages).
The force of friction is 78.4 N
What is force of friction?
Frictional force is the force created when two surfaces come into contact and slide against each other. it is given by the equation:
μ * 
where,
= force of friction
μ = coefficient of friction
= normal force
Given,
μ 
We know,


Subsituing the values in equation:
μ * 

The force of friction is 78.4 N.
