Determine the image distance and image height for a 5.00 cm tall object placed 30.0 cm from a double convex lens with a focal le
vlabodo [156]

Answer:

The image distance is 30 cm

image height = - 5 cm

Explanation:

The formula for calculating the image distance is expressed as

1/f = 1/u + 1/v

where

f is the focal length

u is the object distance

v is the image distance

From the information given,

u = 30

f = 15

By substituting these values into the formula,

1/15 = 1/30 + 1/v

1/v = 1/15 - 1/30 = (2 - 1)/30 = 1/30

Taking the reciprocal of both sides,

v = 30

The image distance is 30 cm

magnification = image height/object height = - v/u

Given that object height = 5 cm, then

image height/5 = - 30/30 = - 1

image height = - 5 * 1

image height = - 5 cm

A French submarine and a U.S. submarine move toward each other during maneuvers in motionless water in the North Atlantic. The F
Mandarinka [93]

Answer:

f_{U}= 1019.72hz

Explanation:

From the equation we are told that:

Velocity of French sub V_{U}= 43.00km/h

Velocity of U.S. sub at V_{F}|=64.00 km//h

French Wave Frequency  F_{F}=1000Hz

Velocity of wave  V_{s}=5470 km/h

Generally the equation for Signal's frequency as detected by the U.S. is mathematically given by

Doppler effect

 f_{U} = \frac{ f_F (vs + v_{U})}{(v_s - v_F) }

 f_{U}= \frac{ 1000 x ( 5470+64)}{(5470-43)}

 f_{U}= 1019.72hz

Use F = 1/T as your basis:
skelet666 [1.2K]
  • Time Period=T=2.5×10^{-3}s

Now

Frequency:-

\\ \rm\rightarrowtail \nu=\dfrac{1}{T}

\\ \rm\rightarrowtail \nu=\dfrac{1}{2.5\times 10^{-3}}

\\ \rm\rightarrowtail \nu=0.4\times 10^{3}

\\ \rm\rightarrowtail \nu=400Hz
