Answer:
All of the above. If you had to pick one it would be D.
Explanation:
The sun gives off many kinds of radiation other than light and heat it also Emits radio waves ultraviolet rays and x-rays
Answer: amplitude
Explanation: This describes the maximum amount of the displacement of a particle from it rest position. Usually, it is measured in metres
Since we are considering AM which is amplitude modulation, a technique used in electronic communication, most commonly for broadcasting information through a radio carrier wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is diversified in proportion to that of the message signal being broadcasted.
The magnitude will be =23.94 WS and the direction will be =98.48 m/s
Answer:
1275.61° C
Explanation:
The resistance of a conductor varies as a function of temperature and it is given as follows
![R= R_o[1+\alpha(T-T_0)]](https://tex.z-dn.net/?f=R%3D%20R_o%5B1%2B%5Calpha%28T-T_0%29%5D)
R_0 is the resistance at temperature T_0, R is the resistance at T and α is the coefficient of temperature of resistance
α= 0.0045/°C
R_0 = 20.3Ω T_0 = 20°C and R= 135Ω
![135= 20.3[1+0.0045(T-20)]](https://tex.z-dn.net/?f=135%3D%2020.3%5B1%2B0.0045%28T-20%29%5D)
T= 1275.61° C
Therefore the temperature of the hot filament = 1275.61° C
