Step-by-step explanation:
Answer:
d. 1.5, 1.25, 0, -0.5, -5
Step-by-step explanation:
1.5 > 1.25 > 0 > -0.5 > -5
Well it is obvious that 1.5vis greater than 1.25.
0 is greater than any negative integers, and that the higher negative number it's value is lower. For example:
-10,000 is less than -100
-4 is greater than -10
It would take the second computer 75 seconds because:
Answer: b) 6
Step-by-step explanation:
Given : The illuminance of a surface varies inversely with the square of its distance from the light source.
i.e. for d distance and l luminance , we have
, where k is constant. (1)
If the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters.
From (1), we have
(2)
For the distance (d) corresponds to the illuminance to 30 lumens per square meter , we have
Put value of k , we get
Then , the number of meters should the distance of the surface from the source be increased= 12 meters- 6 meters = 6 meters.
