Answer:
2.5 cm
Explanation:
Using the relation :
Refractive index = Real Depth / Apparent depth
Refractive index = 1.6
Real depth = 4cm
Virtual depth = apparent depth = x
1.6 = 4cm / x
1.6x = 4
x = 4 / 1.6
x = 2.5
Hence, virtual depth = 2.5cm
The Answer Is - 0.58 Kilogram's
Hope This Help's
The answer is 17 m because you have to add the 15 m and the 8 m together to get the answer so it will be like this 17x17 = 15x15 + 8x8 got it?
Answer:
C. water is more dense and viscous
Explanation:
Rapid gas exchange can be accomplished more easily in air than in water because water is more dense and viscous.
Gases have the greatest ease of diffusion of their respective particles, as occurs in air, since their molecules have higher speeds and have more distance from each other than liquids.
The molecular diffusion rate in liquids is much less than in gases. The molecules of a liquid are very close (liquids are more dense and viscous) to each other compared to those of a gas, then the gas molecules hits with the molecules of the liquid with more frequency and this causes that the gas moves slower than in other gas (for example in air).
Answer:
<h2>A. 80 m/s </h2>
Explanation:
The velocity of the spacecraft can be found by using the formula
p is the momentum
m is the mass
From the question we have
We have the final answer as
<h3>80 m/s</h3>
Hope this helps you
