It depends on two factors: The direction of application of force and the coefficient of friction, 
, between the object and the surface on which the object is placed.
If the direction of application of force is vertically downwards, then the object will not move for any value of .
If the coefficient of friction is zero, 
, then any value of force that is not in a vertically downward direction, the object will move.
If the direction of application of force is not vertically downwards, then it depends on the value of frictional force.
Any kind of frequency, including the angular kind, is closely involved with
time. Still, for some unknown reason,you've given us no time information
whatsoever ... a peculiar decision on your part, since we can be sure that
it's right there, inexorably intertwined with the part of the question that you
DID copy and share with us.
Furthermore and moreover, for one with no prior experience with simple
harmonic motion, the many symbols in this question such as ' d ', ' a ',
' << ', ' d₂ ', and ' a₂ ' would be of no help at all to guide him toward a
solution. On the contrary, he would conclude that the question itself
had been posted by some alien life form.
To sum up: Come back and post the drawing that goes along with the
question, make sure you have presented all of the information that the
question includes, and then we'll talk.
The answer is D. To the left with speed 2v
Answer:
Explanation:
We are given that
Current=I=1.75 A
Resistance =R=55.4 ohm
Time=t=9.5 min=
1 min=60 s
We have to find the heat generated by the resistor.
We know that
Heat=E=
Using the formula
Heat,
Hence, the heat generated by the resistor =
Option 3.
