D determined by its temperature
The only force on the system is the mass of the hoop F net = 2.8kg*9.81m/s^2 = 27.468 N The mass equal of the rolling sphere is found by: the sphere rotates around the contact point with the table.
So by applying the theorem of parallel axes, the moment of inertia of the sphere is computed by:I = 2/5*mR^2 for rotation about the center of mass + mR^2 for the distance of the axis of rotation from the center of mass of the sphere.
I = 7/5*mR^2 M = 7/5*m
Therefore, linear acceleration is computed by:F/m = 27.468 / (2.8 + 1/2*2 + 7/5*4) = 27.468/9.4 = 2.922 m/s^2
Answer:
The planet lacks a solid surface and the temperature is too low
Explanation:
Jupiter does not have solid surface as it is made up of swirling gases, mainly hydrogen(90%) and helium(~10%). The swirl comes from massive wind with speed of 335 miles/hour. The temperature in cloud of Jupiter is 145°C which is too low for water to remain in liquid state as the temperature range for liquid water is 0°C to 100°C.
The cold air sinks as it is heavier
