Since the displacement is completely perpendicular to the direction of the applied force, the work done on the bag is zero.
<h3>
When is the Work done on an object ?</h3>
The work is done on an object when the force applied is multiply by the distance moved by the object in the direction of the force applied.
Given that a man carries a hand bag by hanging on his hand moves horizontally where the bag does not up or down.
What is work if the displacement is not in the direction of force ?
The work done can only be zero if the displacement is perpendicular to the direction of force. otherwise, it will not be equal to zero.
Also, the work done will be zero, if the displacement is zero.
In the question above, the displacement is completely perpendicular to the direction of the applied force.
Therefore, the work done on the bag is zero.

Answer:
C
Explanation:
because it not running will set it off course but running all the time it will run. out of fuel
Answer:
25 Nm
Explanation:
Parameters given
Distance of the particle from the origin, r = 2.0 m
Force acting on particle, F = 25 N
Angle of force, θ = 30°
The torque acting on a particle is given as:
τ = r * F * sinθ
Where r = radius of axis of rotation. This is the same as the position of the particle on the x axis.
Therefore, the torque will be:
τ = 2 * 25 * sin30
τ = 25 Nm
The torque acting on the particle is 25 Nm.
The answer is B. natural; artificial

Answer:
one sister, one half-brother, and three cousins.
Explanation:
Kin selection theory also called inclusive fitness theory describes the self-sacrificial behaviour of organism, animal or individual to ensure survival of closely related family at the detriment of the individual's survival in order to preserve genetic fitness or survival and reproductive success of such individual. Therefore saving one sister, one half-brother, and three cousins will preserve the genetic lineage and reproductive success of the genome of interest
