An object is placed 20 cm from a convex lens of focal length 25 cm. is the lens converging or diverging in this case? answer

When object distance is smaller than the focal length of a convex lens, then the rays diverge.

Here, object distance = 20 cm

focal length = 25 cm

20 < 25

Thus, the lens are <u>diverging</u>

<u></u>

<h3>What is focal length?</h3>

The fundamental description of a camera lens is its focal length, which is often expressed in millimeters (mm). It is not a measurement of the physical length of a lens.

But rather a calculation of the optical distance between the focal plane of the camera's digital sensor or 35mm film to the location where light rays converge to make a sharp image of an object. When a lens is focussed to infinity, its focal length can be calculated.

What happens to the volume of an ideal gas as temperature drops

riadik2000 [5.3K]

Based on the ideal gas equation, the pressure (P), volume (V) and temperature (T) corresponding to n moles of an ideal gas are related as:

PV = nRT

where R = gas constant

Under conditions of constant pressure and number of moles:

The volume is directly proportional to the pressure. Therefore, as the temperature drops the volume will also decrease.

V α T

This is also known as the Charles Law.

A car approaches you at a constant speed, sounding its horn, and you hear a frequency of 76 Hz. After the car goes by, you hear

Talja [164]

Answer:

70.07 Hz

Explanation:

Since the sound is moving away from the observer then

$f_o = f_s\frac {(v+vs)}{v}$ and $f_o = f_s\frac {(v-vs)}{v}$ when moving towards observer

With $f_o$ of 76 then taking speed in air as 343 m/s we have

$76 = f_s\times\frac {(343-vs)}{343}$

$f_s=\frac {343\times 76}{343-v_s}$

Similarly, with $f_o$ of 65 we have

$65 = f_s\times\frac {(343+vs)}{343}\\f_s=\frac {343\times 65}{343+v_s}$

Now

$f_s=\frac {343\times 65}{343+v_s}=\frac {343\times 76}{343-v_s}$

v_s=27.76 m/s

Substituting the above into any of the first two equations then we obtain

$f_s=70.07 Hz$

When operated on a household 110.0-V line, typical hair dryers draw about 1650 W of power. We can model the current as a long st

Dimas [21]

Answer:

Current = 15 A

Resistance = 7.33 ohm

Magnetic field = 1.62 x 10^-4 Tesla

Explanation:

V = 110 V, P = 1650 W, r = 1.85 cm,

(a) Let i be the current

P = V x i

i = 1650 / 110 = 15 A

(b) Let R be the resistance

V = i R

R = 110 / 15 = 7.33 Ohm

(c) Let B be the magnetic field

B = μ0 / 4π x 2i / r

B = 10^-7 x 2 x 15 / 0.0185 = 1.62 x 10^-4 Tesla
