According to Edge, its Soprano and contralto<span />
The intensity of a light in a surface follows the inverse square law formula which can be mathematically expressed as,
I = k/d²
where I is intensity, d is distance, and k is the proportionality constant. For us to increase the intensity, we should lower the distance from the source to the surface.
Answer:
Only the 4 th statement is true that is bed 1 and 3 are older than 4.
Explanation:
The 5 beds are numbered from 1 to 5 , 1 being the lowest and 5 being the topmost bed.
We are given 4 statements and we have to find out which all are true.
(<u>a)Bed 4 is older than bed 2 </u>
This is wrong because the lower beds are older than beds that are higher.
<u>(b)Bed 3 is older than beds 2 and 4</u>
This is also wrong because the 2 is older than 3
(<u>c)Bed 5 is the oldest </u>
This is wrong because bed 1 is the oldest
(<u>d)Beds 1 and 3 are older than 4</u>
This is true as lower beds are older

GIVEN:
60 beats per minute
21 beats per minute
find x= how fast would an astronaut be flying away
1 x
----- * ------ = (60x = 21) -------> 60x = 21 ------------> x= 0.35
60 21 ------- -----
60 60
The answer is 0.35 seconds which refers to how fast would an astronaut be flying away from the earth if he has a heart rate of 21 beats/min.
The volumes are 200cm3 and 0.0002m3
