For ice piece 1, place 2 teaspoons of water into one of the spaces in the ice cube tray. To make ice piece 2, place 2 teaspoons of water into the sealable plastic bag. Carefully squeeze as much of the air out of the bag as possible without spilling any water. Then seal the bag. Place the sealed bag on a flat surface in the freezer. Place the ice cube tray in the freezer at the same time. Leave both in the freezer for four hours. Record the start time and the time when you can remove the ice.

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
