I think d is the answer haha
Answer:
The black body temperature of Earth T_e= 180.4 K
Explanation:
Assuming we have to find Black body temperature of the earth.
S0= solar energy striking the earth= 343 Wm^{-2}
\alpaha = 30% = 0.3
\sigma = stephan boltsman constant.= 5.67×10^{-8} Wm^{-2}K^4
T_e= 180.4 K
Answer:
6.54 x 10^-10 N/kg
Explanation:
mass of the shell, M = 135 kg
radius of shell, R = 1.49 m
distance from the centre of the shell, r = 3.71 m
The gravitational filed is given by
E = 6.54 x 10^-10 N/kg
Thus, the gravitational field intensity at a distance 3.71 m is 6.54 x 10^-10 N/kg.
the answer is C.
if the cost of it is too high, then the producer makes no product, resulting in an unsuccessful business
