Answer: If mass remains constant and you double the force you will double the acceleration.
Answer:
The moment of inertia of this sphere is 
.
Explanation:
It is given that,
Mass of the sphere, m = 4.8 kg
Radius of the sphere, r = 22 cm = 0.22 m
Tangential force, F = 11.2 N
The moment of inertia of the uniform sphere is given by :
So, the moment of inertia of this sphere is . Hence, this is the required solution.

The ratio of the turns to the voltage should be equal
i.e: 200/120 = t/12
so the secondary coil should have 20 turns
Explanation:
If both distance and size are proportional to that in the solar system, the model would be essentially useless.
For example, if the sun were represented by a marble 1 cm in diameter, the planet Neptune would be represented by a grain of sand .3 mm in diameter about 32.3 meters (106 ft) away. The largest planet, Jupiter, would be a larger sand grain, 1 mm in diameter, about 5.6 meters from the sun. Earth would be less than 0.1 mm in diameter, about 1 meter away from the sun.
Such a model would barely fit into a gymnasium (basketball court), and the elements of it would be very difficult to find without a map.
