The Correct Answer is <u>D.Infrared/</u> <em>INFARED has a lower frequency than visible light/</em>
<span>The conversion for Kelvin from Celsius is simple since the units change at same rate (degree for degree) but haven't different zero reference. The Kelvin scale represents absolute zero. The celcius scale moves degree per degree with kelvin scale but has a zero based on freezing point of water. The conversion is 273 + (temperature in celcius) = temperature on kelvin scale. Note 273 is a rounded number to nearest whole number. The actual figure is a number with decimal. 273.15 can also be used if you want more significant figures.
so 273 + 78C = 351 K </span>
Answer:
The size of the electric current is 154.74 A.
Explanation:
It is assumed that,
Charge, q = 93 C
Time,
We need to find the size of the electric current. It is equal to the electric charge per unit time. It is given by :
I = 154.74 A
So, the size of the electric current is 154.74 A. Hence, this is the required solution.
Answer:
Distance, d = 99990 meters
Explanation:
It is given that,
Speed of the train, v = 200 km/h = 55.55 m/s
Time taken, t = 1800 s
Let d is the distance covered by the train. We know that the speed of an object is given by total distance covered divided by total time taken. Mathematically, it is given by :
d = 99990 m
So, the distance covered by the train is 99990 meters. Hence, this is the required solution.
