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.
Answer:
See explanation.
Explanation:
If both stars explode in simultaneously in the <em>your </em>frame of reference then obviously you will see the two flashes simultaneously, and therefore, the time difference between the events would be zero.
If however, the stars exploded simultaneously in their frame of reference, then you would not observe the flashes simultaneously. Then the time difference between the events will not be zero, rather, you will observe star B exploding first and star A after.
B evaporation since the water is going up
The correct answer Temporary charge
Answer:
During start total turns

After half of the time total turns

Total number of turns during it stop

After half of the time total turns

Explanation:
Initially the machine is at rest and then starts rotating with speed 3550 rev/min
now we will have

now we know that it took 10 s to reach the speed
so angular acceleration is given as


now it stops in 31 s so the angular deceleration is given as

now initially number of turn to reach the given speed

number of turns during it stop

Now during startup speed after t = 5 s is given as


now during it stop the speed after half the time is given as

now the number of turns is given as
