Answer:
X and Z
Explanation:
Conduction occurs through direct physical contact. Heat transferred from the pot to the handle, and from the handle to the hand, are both examples of conduction.
Answer:
Explanation:
Energy of radiation in eV = 1237.5/280 = 4.42 eV.
Work function = 2.65 eV.
Maximum kinetic energy = 4.42 - 2.65 = 1.77 eV.
-- The net effective resistance of 10-ohms and 4-ohms
in series is 14 ohms.
-- The current in the series loop is I = E/R = 42V/14-ohms = 3 amperes.
Answer:
When the electrical current passes through the conductors, the polarity is changed, and the diaphragm interacts with the permanent magnets, vibrating and creating sound.
