In order to answer this, we will set up a simple ratio as such:
1 calorie = 4.184 joules
1 kilocalorie = 1000 calories
1 kilocalorie = 4,184 joules
250 kilocalories = x joules
Cross multiplying the second and third equations, we get:
x joules = 4,184 * 250
250 kilocalories are equivalent to 1,046 kJ
S=Vt
110=V(72)
110/72=V
V=1.527m/s
Answer:
820 nm
Explanation:
We are given that
Wavelength=
For first minimum therefore
m=0
We know that for destructive interference
Substitute the values
Hence, the distance between two slits that produces the first minimum=820 nm
As the speed increases and the pressure decreases
Kinetic energy is a form of energy that an object or particle has by reaction of its motion.
