Using equation you can solve
Answer:
5.160384 kg*m²/s
Explanation:
The vector angular momentum P can be found using the following expression:
P = I * w
I refers to the inertia, that for a sphere is found using the expression:
I = * m * r² = * 15.5kg * (0.510m)² = 1.61262 kg*m².
The angular velocity w is given by the problem, and has a value of 3.2 rad/s.
Replacing the data we get:
P = 1.61262 kg*m² * 3.2 rad/s = 5.160384 kg*m²/s

Answer:
The temperature is 749.8 K
Explanation:
Final temperature (T2) = (distance apart/thermal coefficient of expansion×length) + initial temperature
distance apart = 1.5 mm = 1.5/1000 = 0.0015 m
thermal coefficient of expansion for copper = 16.6×10^-6/K
Length of copper = 20 cm = 20/100 = 0.2 m
Initial temperature = 25 °C = 25 + 273 = 298 K
T2 = (0.0015/16.6×10^-6×0.2) + 298 = 451.8 + 298 = 749.8 K
I think the answer would be C. because the orbit around the sun compared to the Earth's (Identifies the seasons change and the year) would be longer, but the day is unknown because that is where it would come down to the total mass of the planet and other important factors about the planets properties.
