Answer:
The ratio is 4
Explanation:
The moment of inertia of a solid sphere about a central axis is:
With m the mass and r the radius of the sphere.
For the smaller sphere with mass M and radius R the moment of inertia is:
(1)
For the bigger sphere with mass M and radius 2R the moment of inertia is:
(2)
The ratio between larger of the larger sphere's moment of inertia about a central axis to that of the smaller sphere is the ratio between (2) and (1):
The term cancels, so:
1- You should always have a question for your experiment.
2- You need to conduct background research. It helps to write down your sources so you can cite your references.
3- Propose a hypothesis (educated guess on what you believe the outcome of the experiment will be)
4- Design and perform an experiment to test your hypothesis (include independent and dependent variable)
5- Record observations and analyze what the data means.
6- Conclude whether you need to accept or reject your hypothesis, which accepting means your hypothesis was right and rejected is if it was wrong.
Answer:
0.392
Explanation:
Mm = 0.11Me
Rm = 0.53Re
g = GM / r^2
G = 6.67 * 10^-11
gmars = (G * 0.11Me) / (0.53Re)^2
Recall:
gearth = GMe /Re^2
Hence, gmars in terms of gearth equals
gmars = gearth * (0.11 / 0.53^2)
gmars = gearth * 0.3915984
gmars = 0.392gearth
Hi, this is a question about an experiment, video or lesson you did in class so just look at what you predicted would happen and if it happen then your answer is yes,<span> the aluminum foil and the versoriums </span>did react the way I predicted, but if not then just say no it did not and say how you can improve your predictions
