Force, Work, Power and Energy — Physics STD 10 — Question

Two resistors of 4Ω and 6Ω are connected in parallel to a cell to draw 0.5 A current from the cell.
Draw a labelled circuit diagram showing the above arrangement.

If a fuse contains a 5 A fuse wire and the voltage is 240 V, what is the maximum power (wattage) which may be taken from the circuit?

What do you understand by the statement the refractive index of glass is 1.5 for white light?

The following belong to which class of lever?
Fore-arm

Name the principle on which a transformer works.

A ray of light incident at an angle of incidence ‘i’ passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges from the prism at an angle of emergence ‘e’.
What can you say about the value of the angle of deviation in such a situation?

What is a single movable pulley? What is its mechanical advantage in the ideal case?

Show the path of a ray of light when it travels from air into water, the angle of incidence being 30°. Mark the angle of incidence and the corresponding angle of refraction.

Name the type of energy possessed by a moving bullet.
