Answer:
does this even make sense
Explanation:
Answer:
The focal length of the lens is 5.54 cm and the height of the image is -0.89 cm.
Explanation:
Given that,
Height of object h = 2 cm
Object distance u= -18 cm
Image distance v= 8 cm
We need to calculate the focal length of the lens
Using formula of lens
Where, f = focal length
Put the value into the formula
(II). We need to calculate the height of the image
Using formula of magnification
Put the value into the formula
Hence, The focal length of the lens is 5.54 cm and the height of the image is -0.89 cm.
Answer:
L = 16 [in]
Explanation:
In order to find the arch we must first find the angle that forms the circular sector, using the following formula:
Now using the following equation we can calculate the arc length
The answer is 200, 200 tennis balls would be in 8 bags if they each held 25.
Direction, while speed is simply how fast you are moving, velocity is in a specific direction, and you can have negative velocity if you start moving in the opposite direction.
