Answer:
toward the normal
Explanation:
Light travels at different speed in different mediums.
Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.
Or ,
n = c/v.
Light travels at a slower speed in water as compared to air because there are more number of interfering molecules in the path of the light in case of water as compared to liquid.
When a light travels from lower denser medium say water to higher denser medium say water, it bends towards the perpendicular (normal) as its speed reduces in that medium.
Acceleration is the rate of change of velocity as a function of time. For example a car traveling at 50 km/hr starts to accelerate, 10 seconds after, its speed changes to 100 km/hr then the acceleration of the car during the time can be calculated as below: initial speed = 50 km/hr.
What effect man there are a million effects the only one that arent true are fusion or fission and magnetism unless that bowling ball is iron
Answer:
![d =4.77\times 10^{-5}\ m](https://tex.z-dn.net/?f=d%20%3D4.77%5Ctimes%2010%5E%7B-5%7D%5C%20m)
Explanation:
given
wavelength of light λ = 479 nm
= 479 x 10⁻⁹ m
the angle
θ = 1.15 / 2 = 0.575°
using
condition for diffraction minimum ,
d sinθ = m λ
for first minimum m = 1
d sinθ = λ
therefore ,
slit width
![d =\dfrac{479\times 10^{-9}}{sin 0.575^0}](https://tex.z-dn.net/?f=d%20%3D%5Cdfrac%7B479%5Ctimes%2010%5E%7B-9%7D%7D%7Bsin%200.575%5E0%7D)
hence, the width of the slit is equal to ![d =4.77\times 10^{-5}\ m](https://tex.z-dn.net/?f=d%20%3D4.77%5Ctimes%2010%5E%7B-5%7D%5C%20m)
A) Geothermal
B) Hydroelectric
C)Biomass
D) Wind
I assume this is the four options you had, correct?
i think that biomass is the only one that would release the greenhouse gases. I once heard, it may not be true, that biomass has more co2 released than coal.
