Answer:Vertical Force Only
Explanation:
When a football or any other particle is thrown at an certain angle then at highest point force acting on it is equal to the weight of object because no other force is acting in the vertical direction except gravity(Neglecting air resistance).
As long as there is no Force in Horizontal direction there will only be vertical force acting on the football at highest Point
Answer:
c is the correct option
Explanation:
Electric field strength is high when electric filed lines are closer together(Represented by red lines in the diagram).
Electric potential is the work done in bringing a unit positive charge from one location to another.
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).
Pressure= F/A
Given, F=30 N
Area=20 m^2
Putting values in formula,
Pressure = 30/20
=3/2
=1.5 Pascals
