Answer:
Done
Explanation:
The differences are significant. The main disadvantages of a pinhole camera compared to a modern camera are:
Proper exposure requires a trial and error approach.
Requires manual control of shutter speed (difficult to control)
Poor image quality (due to diffraction effects).
Long exposures (lead to blurry images if the subject moves).
Fixed aperture or f-stop.
Advantages include:
Large depth of field.
Inexpensive
Robust and nearly 100% reliable.
If used properly can create artistic effects.
Answer:
(a) 2.5 cm
(b) Yes
Solution:
As per the question:
Mass of Uranium-235 ion, m = 
Mass of Uranium- 238, m' = 
Velocity, v = 
Magnetic field, B = 0.250 T
q = 3e
Now,
To calculate the path separation while traversing a semi-circle:

The radius of the ion in a magnetic field is given by:
R = 



Now,
By putting suitable values in the above eqn:


(b) Since the order of the distance is in cm, thus clearly this distance is sufficiently large enough in practical for the separation of the two uranium isotopes.
Answer:
the power used by the person is 10 W.
Explanation:
Given;
weight lifted, W = 50 N
distance through which the weight was lifted, d = 2 m
time of motion, t = 10 s
The power used by the person is calculated as;

Therefore, the power used by the person is 10 W.
Answer: To convert this into dimes it's basically like 25 divided by 10.
25 / 10 = 2.5, So you'd need two dimes and a nickel.
