The question seems to be what is an equilibrant force.
The answer is "an added force that produces equilibrium.
Here you have more insight:
<span>an object that has no net force acting on it? This object indeed is in equilibrium but the object is not the equilibran force.
the reaction force in an action-reaction pair of forces?
the reaction force is not an equilibrant force. The reaction force exists always but equilibrium is only possible if the net force is cero.
an added force that produces equilibrium? this is the right answer.</span>
Answer:
load
a generator, a light bulb (load) and a closed switch
Explanation:
as explained in the other question, the fan is using generated electric energy to create mechanical movement. as such it is a load on the grid or circuit or net.
and electric power can only flow, if there is a closed (uninterupted) circuit from the power source to a load and back.
any open switch is an interruption of the circuit.
a buzzer is a kind of switch. it closes the circuit (and puts a load on) only when somebody presses it.
by the way, a closed circuit without a load will "destroy" (short circuit) the power source or at least the wires (burn through).
Answer:
Aim directly at the monkey
Explanation:
Despite the mass differences, both the monkey and the food will experience the same acceleration hence while the food follows a projectile path, it will then fall and hit the monkey hence achieving the aim of feeding it. You don't need to aim below or above, aim it directly.
Answer:
The displacement of the photographer and the astronauts are equal
Explanation:
In this exercise, it is important to differentiate between distance and displacement.
The distance moved by an object describes the total length of change in position irrespective of the objects starting point or the point where the transit stops. Distance is a scalar quantity as it does not specify a direction of which a transit takes place as such a piston moving in oscillatory motion can be said to cover a very long distance considering its number of completed cycles
Displacement unlike distance is a vector quantity which accounts for an objects starting and ending points regardless of the route through which the object completed the distance, as such it is the straight line linking the object starting and stopping points, of which the length of the line is the magnitude of displacement and the direction from the starting point to the end point
As such in the above question the displacement of the photographer is his transit from Florida to California while the displacement of the astronauts is also from Florida and stopping at California both of which are equal
