Specify whether the boiling point, as determined in the miniscale boiling-point apparatus, is the temperature a. of the liquid at the timebubbles first emerge slowly from the liquid. b. at the vapor-liquid interface above the surface of the boiling liquid while a drop of liquid c. is suspended from the thermometer. d. of the liquid at the timebubbles emerge rapidly from the liquid. e. of the heating source at the timebubbles emerge rapidly from the liquid.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.
