The resistance of the heating element is 21.61 Ω
Given
The power dissipated = 1500 W
Voltage = 180 V
We know that
Power = Voltage * Current
⇒ Power / Voltage = Current
⇒ 1500 W/180 V = Current
⇒ 8.33 A = Current
In order to calculate the resistance of the heating element. We Have to apply the formula
Power = (Current)^2 * Resistance
⇒ Resistance = Power / (Current)^2
⇒ Resistance = 1500 W/ (8.33) ^2
⇒ Resistance = 21.61 Ω
Hence the resistance of the heating element is 21.61 Ω

Answer: refraction
Explanation: this is because during refraction light moves from one medium to another.
Answer:
-245.7°C es la temperatura del gas bajo 100 torr
Explanation:
Para resolver esta pregunta debemos hacer uso de la ley de Boyle que establece que la presión de un gas es directamente proporcional a la temperatura de este cuando el volumen permanece constante. La ecuación es:
P1T2 = P2T1
<em>Donde P es presión y T temperatura absoluta del estado inicial, 1, y final, 2.</em>
<em />
Reemplazando:
P1 = 1000torr
T2 = ? -Incógnita-
P2 = 100torr
T1 = 273K -Temperatura del hielo fundido = 0°C = 273K
1000torrT2 = 100torr273
T2 = 27.3K
27.3K - 273 =

The final velocity of Bill after he catches the pillow is 4.44 m/s.
The given parameters:
- Mass of Bill, m1 = 77 kg
- Velocity of Bill, u1 = 2.6 m/s
- Mass of the pillow, m2 = 6.9 kg
- Initial velocity of the pillow, u2 = 25 m/s
<h3>What is conservation of linear momentum?</h3>
- The principle of conservation of linear momentum states that the total momentum of an isolated system is constant.
The final velocity of Bill is determined by applying the principle of conservation of linear momentum as follows;
Thus, the final velocity of Bill after he catches the pillow is 4.44 m/s.
