inverted, real, behind the lens is the answer

kifflom [539]3 years ago
7 0

Answer:

Inverted

Real

Behind the lens

Explanation:

As we know that

d_o = 16 cm

d_i = 16 cm

also we know that

h_o = 4 cm

h_i = -4 cm

now we know that magnification is given by

M = \frac{d_i}{d_o} = \frac{h_i}{h_o}

so we can say here that

M = 1

so here image size will be same as object size and it must be real and inverted as magnification is negative in sign

American eels (Anguilla rostrata) are freshwater fish with long, slender bodies that we can treat as a uniform cylinder 1.0 m lo
madam [21]

Answer:

option D

Explanation:

given,

uniform length of cylinder = 1 m

diameter of the cylinder = 10 cm = 0.1 m

Eels have been recorded to spin = 14 rev/s

camera records at = 120 frames per second

time = \dfrac{1}{120}\ s/frame

angle at which eel rotate = ?

ω = 14 rev/s

ω = 14 x 2 π rad/s

ω = 28 π rad/s

angle at which eel rotate

 θ = ω t

θ = 28\pi\times \dfrac{1}{120}

θ = 0.733 rad

θ =0.733 \times \dfrac{180^0}{2\pi}

θ =42^0

Hence, the correct answer is option D

What is the most effective way to prevent beach erosion?
sergiy2304 [10]
The most effective way to prevent beach erosion is to replant mangrove trees, seaweeds and seagrass. The strategic planting of vegetation can be used to help control erosion. The roots of these plants help to anchor the sand and ensure that it is not carried off in erosion. This is why many areas plant seagrass and build marshes along coasts to prevent erosion.
