Answer:
The centripetal acceleration of the satellite is 
.
Explanation:
Given that,
The distance covered by a geosynchronous satellite, d = 42250 km
The time taken by the satellite to covered distance, t = 1 day = 24 hours
Since, 24 hours = 86400 seconds
Let v is the speed of the satellite. It is given by the total distance divided by total time taken such that :
v = 3072.5 m/s
The centripetal acceleration of the satellite is given by :
So, the centripetal acceleration of the satellite is . Hence, this is the required solution.
The image of the black body curve is missing, so i have attached it.
Answer:
T ≈ 3372 K
Explanation:
From the attached curve of the black star, if we trace the peak value of the wavelength from the graph, we will see that it is approximately 859.5 nm.
Thus; λ_peak = 859.5 × 10^(-9) m
From wiens law, we know that;
T•λ_peak = 2.898 × 10^(-3) m.K
Where T is surface temperature.
Plugging in the relevant values, we can find the temperature T
Thus;
T = (2.898 × 10^(-3))/(859.5 × 10^(-9))
T ≈ 3372 K
The answer would be C. velocity. When white light enters a prism it is refracted. This refraction is caused due to a change in velocity (generally speaking, velocity is considered speed in some cases) when entering the prism. In other words, when light enters a prism at an angle, the glass slows down the light causing the light to split into different colors.
