A coil X is moved quickly away from the end Y of a stationary metal bar and a current then flows in X as shown above. Then

A. the bar is not a magnet B. Y is a north pole C. Y is a South pole D. Y repels coil X Correct Answer: Option B B. Y is a north pole Explanation N – S magnet is moved towards a coil production clockwise direction of current in the coil. – This is the same...

If a body moves with a constant speed and at the same time undergoes an acceleration, its motion is said to be?

A. circular B. oscillatory C. rectilinear D. rotational Correct Answer: Option A A. circular

The lower fixed part of a faulty thermometer reads 2°C while the upper fixed point is 100°C. What is the true temperature when the thermometer reads 51°C?

by Sunday | Jan 4 | Physics WAEC

A. 52°C B. 50°C C. 49°C D. 46°C Correct Answer: Option B B. 50°C

The resultant capacitance in the figure above is?

by Sunday | Jan 4 | Physics WAEC

A. 0.4μf B. 0.8μf C. 1.8μf D. 4.5μf Correct Answer: Option B Explanation For the parallel arrangement = 2 + 4 = 6μf For the series arrangement = 1/CT = 1/2 + 1/3 + 1/6 + 1/4 1/CT = 15/12 CT = 12/15 = 0.8μf...
