Series circuits - cpt connected so that the same current passes through each of them.
Disconnection/break in series circuit and current doesn't flow.
Current same
The total potential difference across all of the components. (the sum of the pds across the individual series elements).
The diagram in the enclosure seems to show resistors in parallel. Which is a bit confusing ...
Nevermind that one i dont know sorry
The heat transferred by room heater to the room is an example of convection heat flow.
Answer: Option D
<u>Explanation:</u>
It is known that heat or thermal energy generally flows from high temperature to low temperature. Heat can be transferred in four ways. They are conduction, convection, radiation and electro-magnetic waves. So, in the present case, if we are turning on the heater highers the temperature of the room, we need to use room heaters. And generally room heaters utilize convection technology to flow the heat energy.
In convection mode of heat flow, the heat energy generated at the source i.e., in the coils of the room heater is made to flow away from the source using the fan or radiator kind of thing. So, this process of transfer of heat energy from the point of generation by making the heat flow or rise is termed as convection. And thus, convection is the best example which is used in room heater.
Answer:
ball will oscillate in between the plates
Explanation:
The metallic coated styrofoam lowered in between two large metal plates, a large potential difference V is kept between the two plates, will experience a force of repulsion ( because both plates and balls will have similar kind of charges and like charges repel each other) from the opposite plates.
If we consider d as the distance between the plates, E as electric field because of Potential difference V. Then force F experience by the ball will be

where q be the total charge on the metallic coated ball.
clearly, since, both the plates will repel the ball in opposite directions, hence ball will be in oscillate in between the plates.
Answer:
Work done by friction along the motion is given as

Explanation:
As per work energy theorem we can say
Work done by all forces = change in kinetic energy of the system
so here car is moving from bottom to top
so here the change in kinetic energy is total work done on the car
so here we will have


now plug in all data in it
