What is the focal length of this lens in air?
Answer:
The focal length is 12 cm and the lens is converging.
Explanation:
Given that,
Radius, R ₁=10 cm
R₂ =15 cm
Index of refraction n= 1.5
We need to calculate the focal length of the lens
Using formula of focal length
Put the value into the formula
The focal length of the lens is positive so the lens is converging.
Hence, The focal length is 12 cm and the lens is converging.
A biconvex lens is a type of converging lens. Using the Lensmaker's formula and the given values, the focal length of the lens in air is calculated to be 30cm.
A biconvex lens, which is defined by both surfaces of the lens bulging outwards, is a form of converging lens due to its ability to bend parallel light rays toward a single focal point after they pass through the lens. The focal length of the lens can be calculated using the Lensmaker's formula, which is 1/f = (n-1)[(1/R1) - (1/R2)]. Applying the given values, we find that the focal length f = 1/[(1.5-1)[(1/10)-(1/15)]] = 30cm.
Therefore, this biconvex lens is a converging lens with a focal length of 30cm in air.

6001 pounds is slightly more than 3 tons. This is because, in the comparison scale, 1 ton is equal to 2000 pounds. So, 3 tons equals 6000 pounds.
The student is asking which is more, 3 tons or 6001 pounds. To determine this, we need to understand the relationship between tons and pounds. We know that 1 ton is equivalent to 2000 pounds. So, 3 tons would be equivalent to 3*2000 = 6000 pounds.
Hence, comparing 6001 pounds with 3 tons, or effectively 6000 pounds, 6001 pounds is slightly more than 3 tons.

Oh, I just realized you asked for a body part, and there is only one body part in the circulatory system, my bad. That would be the heart. But, it also contains veins, arteries, capillaries, and blood. It's main function to pump blood to supply oxygen to the body.
Hope this helps!
