The system includes a disk rotating on a frictionless axle and a bit of clay transferring towards it, as proven withinside the determine above.
<h3>What is the
angular momentum?</h3>
The angular momentum of the device earlier than and after the clay sticks can be the same.
Conservation of angular momentum the precept of conservation of angular momentum states that the whole angular momentum is usually conserved.
- Li = Lf where;
- li is the preliminary second of inertia
- If is the very last second of inertia
- wi is the preliminary angular velocity
- wf is the very last angular velocity
- Li is the preliminary angular momentum
- Lf is the very last angular momentum
Thus, the angular momentum of the device earlier than and after the clay sticks can be the same.

Build a linear search following the pseudocode approach above.
Explanation:
Using the main below and the outline above, complete the iterative file searching algorithm in the method searchFiles(). Use fileObject.listFiles(), fileObject.isDirectory(), and fileObject.getName() to accomplish this below.
public static void main(String[] args) {
System.out.println( searchFiles(new File(“c:\\”), “hw3.zip”) );
}
public static String searchFiles(File path, String target) {

Answer:
Explanation:
The concept of heat transfer is applied, by first equation the heat generated to the heat trasnfer by convection to get the temperature of the outer surface.
Also equating the head conducted to the heat generated to get the temperature of the inside surfaces. Tthe steps and detailed calculations is as shown in the attachment.
Answer:
a) the power consumption of the LEDs is 0.25 watt
b) the LEDs drew 0.0555 Amp current
Explanation:
Given the data in the question;
Three AAA Batteries;
<---- 1000mAh [ + -] 1.5 v ------1000mAh [ + -] 1.5 v --------1000mAh [ + -] 1.5 v------
so V_total = 3 × 1.5 = 4.5V
a) the power consumption of the LEDs
I_battery = 1000 mAh / 18hrs { for 18 hrs}
I_battery = 1/18 Amp { delivery by battery}
so consumption by led = I × V_total
we substitute
⇒ 1/18 × 4.5
P = 0.25 watt
Therefore the power consumption of the LEDs is 0.25 watt
b) How much current do the LEDs draw
I_Draw = I_battery = 1/18 Amp = 0.0555 Amp
Therefore the LEDs drew 0.0555 Amp current
