A hypothetical planet has a radius 1.5 times that of Earth, but has the same mass. What is the acceleration due to gravity near its surface?
Step 1 of 3
Solution 31P a.Consider the door width as w,then the moment of inertia will be expressed as I = Mw 2 Here M is mass of the door M = 25 kg w is width of the door=0.91 m The torque exerted by door =5.2 N/m When the torque is applied on an object that rotating about field axis then that object will undergo angular acceleration.the angular acceleration is quantitative expression of the change in angular velocity that a spinning object...
