A generic solid, X, has a molar mass of 60.2 g/mol. In a constant‑pressure calorimeter, 34.1 g of X is dissolved in 283 g of wat
er at 23.00 °C. X ( s ) ⟶ X ( aq ) The temperature of the resulting solution rises to 27.30 °C. Assume the solution has the same specific heat as water, 4.184 J/(g·°C), and that there is negligible heat loss to the surroundings. How much heat was absorbed by the solution?

Answer:
Explanation:
When an electromagnetic wave passes through the interface between two mediums, it undergoes refraction, which means that it bents and its speed and its wavelength change.
In particular, the wavelength of an electromagnetic wave in a certain medium is related to the index of refraction of the medium by:
where
is the wavelength in a vacuum (air is a good approximation of vacuum)
n is the refractive index of the medium
In this problem:
is the original wavelength of the wave
n = 1.47 is the index of refraction of corn oil
Therefore, the wavelength of the electromagnetic wave in corn oil is:
Answer:
Explanation:
1 full revolution is let \theta be the angle of Ron's position.
At t = 0.
one full revolution occurs in 12 sec, so his angle at t time is
r is radius of circle and it is given as
for r = 30 sec
however, that is centered at (0,0) and the positioned at time t = 0 is (30,0). it is need to shift so that the start position is (30,45). it can be done by adding to y
