A force of 5 N gives mass m1 acceleration 8 m/s² and mass m2 acceleration 24 m/s². What acceleration would it give if both masses tied together? MCQ with Answer and Explanation

Explanation:
Latent heat per unit mass, so Q = mL, L = Q/m, unit J/kg (or cal/g). Specific latent heat of fusion/vaporization. Heat required for phase change without temperature change.

Explanation:
While James Clerk Maxwell predicted electromagnetic waves mathematically, it was the German physicist Heinrich Hertz who successfully built the first spark-gap transmitter in 1887. He physically generated and detected radio waves in his laboratory, proving Maxwell's theories right. The SI unit of frequency, the Hertz (Hz), is named in his absolute honor.

Explanation:
Work = force × displacement in direction of force. Displacement zero, so work zero. Physiology work is done internally, but physics work zero.
