Questions that might come up on the JAMB Physics exam
Here are some of the UTME physics questions that come up most often, but there are still more. But I try to get something out of them to get things ready for you.
(1) Velocity, acceleration, moment, displacement, force, electric field strength, and magnetic flux are all examples of vector quantities.
(2) Work, time, mass, distance, energy, pressure, speed, and temperature are all scalar quantities.
(3) When the angle between two forces acting on an object is –0o, the resultant force is at its highest level.
(4) Compared to the astronomical telescope, the terrestrial telescope has one more lens. The extra lens is for putting the image in the right place.
(5) At the magnetic equator, what is the angle of dip? – 0o
(6) When an a.c. circuit is at resonance, the phase angle is 0o.
(7) The process by which the sun gets its energy is: nuclear fusion
(8) A transistor is mostly a switch and an amplifier.
(9) Eddy currents waste less energy when you use soft iron wires that have been insulated.
(10) When a particle in a fluid reaches its maximum speed, the weight of the particle is equal to the force that slows it down.
(11) Water doesn’t work well as a thermometer because it – wet glass
(12) For a concave mirror to make a bigger and straighter image, the object must be placed between the main focus and the pole.
(13) Reverberation is the process by which sound stays after its source has been taken away.
(14) The colors you see in soap bubbles are caused by:
(15) Infra-red is the type of electromagnetic wave that can heat up the environment.
(16) A controlled number of – trivalent atoms can be added to pure silicon to make it a p-type material.
(17) In a nuclear reactor, nuclear fission happens because of a particle called a neutron.
(18) The carbon-granule microphone uses the change-in-resistance principle.
(19) Fog is what happens when water droplets in the air mix with dust particles in the air to make it hard to see.
(20) In a semiconducting junction diode, the depletion or barrier layer gets thinner as the forward bias increases.
(21) When the pressure on a fluid goes up, its thickness goes up.
(22) To turn a d.c. dynamo into an a.c. dynamo, replace the commutator with slip rings.
(23) Polarization is a way to tell the difference between transverse waves and longitudinal waves.
(24) Because of a property called “magnetic dipole,” the North pole of a magnet can never be separated from the South pole.
25) Electrons and ions are what carry the charge in gases.
(26) A cathode ray is a type of ray that makes gas molecules light up.
(27) Lenz’s law is a rule about how energy stays the same.
(28) Diffraction is the process by which light bends around an obstacle.
(29) A moving iron ammeter can measure both alternating current and direct current.
(30) What is the least mistake that could happen if you use a ruler that is marked in centimeters? – 0.5 cm
I have made a Physics guide for the JAMB UTME for people who want to know what questions and answers are likely to come up, especially when it comes to calculations. Click here to get a guide and download for prep physics.
There will be more questions on the JAMB Physics test (1) The thing moves in a circle at the same speed. Its acceleration stays the same in size but changes in direction.
(2) The movement of a talking drum’s moving skin is rightly called oscillatory.
(3) Isotopes are made up of nuclei with? – same number of atoms, but different mass numbers
(4) The atom has no net charge because the neutrons surround the charged protons like a shield.
(5) Gases carry electricity when the pressure is low and the voltage is high.
(6) In an a.c. circuit with a resistor, a capacitor, and an inductor, resonance happens when the frequency source is set so that the reactance of the capacitor is equal to the reactance of the inductor.
(7) In a pure inductive circuit, the current is 90 degrees out of phase with the voltage.
(8) Faraday’s law is the main idea behind how an induction coil works.
(9) A dynamo primarily converts – mechanical energy into electrical energy
10) To change a millimeter to an ammeter: There needs to be a low resistance in series.
(11) To turn a galvanometer into an ammeter, you connect a low resistance shunt in parallel with it.
(12) If the currents in two parallel conductors flow in the same direction, the conductors will:
(13) The emf of a cell is measured with a calibrated potentiometer, which doesn’t draw any current from the cell.
(14) An open series circuit has an infinite amount of resistance.
(15) When a spectrometer breaks up white light, the part with the shortest wavelength is violet.
I hope that the UTME Physics past questions have helped you figure out what the most likely hot topics will be on the JAMB Physics exam. You can use these topics and questions to help you get ready for your CBT.
