Answer:
102.2 degrees Fahrenheit
Explanation:
You can use this formula in order to convert from Celsius to Fahrenheit:
(C x 9/5) +32
39 x 9 = 351
351 / 5 = 70.2
70.2 + 32 = 102.2
Answer:
500 nm
Explanation:
In this problem, we have a diffraction pattern created by light passing through a diffraction grating.
The formula to find a maximum in the pattern produced by a diffraction grating is the following:

where:
d is the distance between the lines in the grating
is the angle at which the maximum is located
m is the order of the maximum
is the wavelength of the light used
In this problem we have:
is the angle at which is located the 2nd-order bright line, which is the 2nd maximum
n = 5000 lines/cm is the number of lines per centimetre, so the distance between two lines is

Re-arranging the equation for
, we find the wavelength of the light used:

Yes there is a difference.
Answer:
The angle of the incline above horizontal is 17.81 degrees.
Explanation:
Given that,
Mass of the object, m = 4 kg
Acceleration of the object above the incline, 
We need to find the angle of the incline above horizontal. The net force acting on the object along the incline is given by :






So, the angle of the incline above horizontal is 17.81 degrees. Hence, this is the required solution.
