Answer:
The intensity of light from the 1mm from the central maximu is
Explanation:
From the question we are told that
The wavelength is
The width of the slit is
The distance from the screen is
The intensity at the central maximum is
The distance from the central maximum is
Let z be the the distance of a point with intensity I from central maximum
Then we can represent this intensity as
Now the relationship between D and z can be represented using the SOHCAHTOA rule i.e
if the angle between the the light at z and the central maximum is small
Then
Which implies that
substituting this into the equation for the intensity
given that
We have that
I believe
the answer is C. 0.14cm.
The zero error in vernier caliper is read by the distance by which the zero of the movable part of the scale is shifted from the zero of the cm ruler in the tool, which is the unmovable part of the tool. The movable part has a scale accuracy of 0.1 cm, while the other has a scale accuracy of 1 cm. And we always use the lowest scale, which is here the 0.1 scale which has greater accuracy with 10 times the 1 cm ruler, to find our errors.
Hope this helps!
Answer:
Gravity
Explanation:
Gravity pulls things down to earth and it is a force
Oxid ion is what it is called
Answer:
ΔV= -5.833×10⁻³
Negative sign indicates that volume decreases
Explanation:
Given data
System heat gains Q=3220 J
Pressure P=1.32×10⁵Pa
Internal energy increases ΔU=3990 J
To find
Change in volume ΔV
Solution
First we need to find the work done
So
W=Q-ΔU
W=3220J-3990J
W= -770J
Now for the change in volume at constant pressure
ΔV=(W/P)
ΔV= -5.833×10⁻³
Negative sign indicates that volume decreases
