Answer:
A: They produce a real image.
Explanation:
The images formed on the retina of the eye for a normal visibility must always be real.
Only a real image can be physically projected on any physical object whereas the virtual images are visible due to reflections.
- The nearsightedness is corrected with the help of a concave lens since it is the condition of the eye lens remaining thick and curved to converge the rays entering the eyes after a shorter distance which results in their image formation even before the retinal surface so to initially diverge them a bit so that they converge on the retinal surface and form the image there we use concave lens. Vice-versa of the above justification in the case of farsightedness.
Answer:
if you can show us the available answers i would be able to hleo you
Explanation:
Answer:
Part A 2.88 A, PART B 28.82 mA PART C 0.288 mA
Explanation:
We have given angular frequency
Voltage source has an amplitude of 24.5 V, So V= 24.5 volt
Part A
We have given inductance
So inductive reactance
So current
Part B
We have given inductance
So inductive reactance
So current
Part C
We have given inductance
So inductive reactance
So current
Answer:
8.7 m/s
Explanation:
Given data
Mass= 0.6kg
radius= 0.9m
Force= 50N
A. Please see attached the FBD of the stone
B. Apply the formula
F= mv^2/r
Substitute
50= 0.6*v^2/0.9
cross multiply
50*0.9= 0.6v^2
45= 0.6v^2
v^2= 45/0.6
v^2= 75
v= √75
v= 8.7 m/s
Hence the maximum speed attained without breaking the string is 8.7 m/s
The observer will hear a sound whose frequency (pitch) is lower than the source is actually emitting.
