Answer:
8.66 nano seconds
Explanation:
speed of k mesons ( v ) = c m/s
Distance between counters ( d ) = 9.00 m
number of countable electrical pulses = 1000 counts in first counter and 250 in second counter
time of travel = d / v = 18 / secs
Next write the decay of particles in lab frame
finally calculate the half life of Meson in its own frame
( t 1/2) of meson in its own frame = 8.66 n-secs
attached below is a detailed solution
Answer:
Pressure increases as you move deeper below earth's surface.
Tempurature increases as you move deeper below earth's surface.
Hope this helps!
Explanation:
Answer:
This could represent something like sliding a small rock across an icy lake.
Explanation:
A 20N force of gravity (weight), and 20N normal force exerted back onto the object imply it is on the ground and has no vertical motion. There is a net force of 0N
An 80N force to the left and a 5N force to the right create a net force of 75N to the left. This means that there is a force acting on the object that makes it accelerate to the left. 80N represents a push or pull force and 5N represents a relatively small frictional force due to the object being slid on a surface such as steel or in this case ice.
Answer:
<h3>(A) The width
m</h3><h3>(B) The new width is
m</h3>
Explanation:
Given :
Focal length
Maximum aperture
Wavelength m
(A)
From rayleigh criterion,
rad
From angle formula,
Where 12 m ( given in example )
m
m
(B)
We know that is proportional to the and inversely proportional to the
so we write the new width, here is 5.5 times larger than above case
m
