Answer: 9/4n
Explanation:
Let's take T to represent tank
When n litres of fuel was added to tank that was 1/3 full = n + 1/3T
The tank was 7/9T
n+1/3T = 7/9T
n =7/9T - 1/3T
n = 4/9
If a full tank is taken to be 1 = 9/9
Hence, we will have 1 = x × n
1 = x × 4/9
x = 9/4
Hence 9/4 of n = 9/4n
More work was done in the skateboard that came to a stop because the one that rolled across the room moved on a surface with less friction while the second board used more work to move on a surface with much friction.
b. Refraction
Explanation:
Fish in the aquarium are looking much bigger than they are due to refraction.
Refraction causes the path of light to bend and the velocity and wavelength attenuated.
This phenomenon occurs when light travels between two materials of different densities.
- Air has a refractive index of 1
- Water has a refractive index of 1.33
- When light form water comes to air, the their angle changes.
- This causes the magnification of the fish.
