Equilibrium is when the opposing forces or influences are balanced. So it would be E!
For all antinodal positions we know that
now we also know the relation between phase difference and path difference
now we will have
now from above equation we will have
now for the first anti node position
N = 1
Option D is correct
False because friction will generate heat energy and/or sound energy etc. Think of a car stopping or a broom sweeping the ground.
u = 0.077
Explanation:
Work done by friction is
Wf = ∆KE + ∆PE
-umgx = ∆KE,. ∆PE =0 (level ice surface)
-umgx = KEf - KEi = -(1/2)mv^2
Solving for u,
u = v^2/2gx
= (12 m/s)^2/2(9.8 m/s^2)(95 m)
= 0.077
Answer:
Number of absent affects the grade
Explanation:
the dependent variable is the grade and the independent variable is the number of absent, since the grade depends of the number of absents.
