Answer:
a)
b)
Explanation:
We are comparing two wavelengths with the radius and diameter constant, and if we want to compare it, we need to use the following formula:
Where represent the angular resolution and the wavelength.
So if we have a fixed resolution and wavelength 1 and we want to find the resolution for a new condition we can solve for and we got
Part a
For this case the subindex 1 is for the color red and we know that:
And the angular resolution for the color red is specified as
And for the infrared case we know that , so if we replace we got:
Part b
For this case the subindex 1 is for the color red and we know that:
And the angular resolution for the color red is specified as
And for the ultraviolet case we know that , so if we replace we got:
Answer:
The coefficient of kinetic friction is 0.26
Explanation:
Given:
Mass of box kg
Initial height m
Final height m
Distance travel by block m
For finding coefficient of kinetic friction,
We use conservation laws,
Work done by frictional force is equal to change in energy,
Here only potential energy change so we can write,
Here
Therefore, the coefficient of kinetic friction is 0.26
Acceleration = V/t
First set velocity to m/s
V = 72.42 m/s
Now we divide velocity by time
A = 72.42/39.5
A = 1.83 m/s^2
This would be called genetic mutation because as stated above neither of it's parents have it so say for humans both parents have 2 arms which is normal but they have a kid and the he/she only has one arm thus genetic mutation anyway good luck on your work
