Tambayoyi (20) da suke yawan fitowa Physics a Jarrabawar JAMB tare da amsa..
(1) Example of vector quantity:
Ans=
velocity, acceleration, moment, displacement, force, electric field intensity, magnetic flux
(2) Examples of scalar quantity: Ans= work, time, mass, distance, energy, pressure, speed, temperature
(3) The resultant of two forces acting on an object is maximum if the angle between them is:
Ans= 0o
(4) The terrestrial telescope has one extra lens more than the astronomical telescope. The extra lens is for -erection of the image
(5) What is the angle of dip at the magnetic equator? Ans= 0o
(6) At resonance, the phase angle in an a.c. circuit is = 0o
(7) The process of energy production in the sun is = Nuclear fusion
(8) A transistor functions mainly as a = switch and amplifier
(9) Energy losses through eddy currents are reduced by using = insulated soft iron wires
(10) The effect of a particle in a fluid attaining its terminal velocity is that the = weight is equal to the retarding force
(11) Water is a poor thermometric liquid because it = wet glass
(12) To produce an enlarged and erect image with a concave mirror, the object must be positioned = between the principal focus and the pole
(13) The phenomenon that makes sound persist when its source has been removed is known as = reverberation
(14) The colours seen in soap bubbles are due to = dispersion
(15) The electromagnetic wave that can produce a heating effect on the environment is = infra-red
(16) Pure silicon can be converted to a p-type material by adding a controlled amount of = trivalent atoms
(17) The particle that is responsible for nuclear fission in a nuclear reactor is = neutron
(18) The carbon-granule microphone works on the principle of change in = resistance
(19) The phenomenon whereby the water droplets in the atmosphere combine with dust particles in the air to reduce visibility is = fog
(20) In a semi-conductor junction diode, as the depletion or barrier layer is forward biased, the layer = narrows.
