Answer: attractive
Explanation:
According to Newton's law of Gravitation, the gravitational force 
exerted between two bodies of masses 
and 
and separated by a distance 
is equal to the product of their masses and inversely proportional to the square of the distance:
Where:
is the Gravitational Constant
and are the masses of the objects
is the distance between the objects
It should be noted: this force is a central force and is attractive.
Answer:
c.
Explanation:
they are all almost correct.
c is the only fully correct option
Answer:
m = 1.99 kg = 2 kg
Explanation:
The moment of inertia of a bicycle rim about it's center is given by the following formula:
where,
I = Moment of Inertia of the Bicycle Rim = 0.21 kg.m²
r = Radius of the Bicycle Rim = Diameter of the Bicycle Rim/2
r = 0.65 m/2 = 0.325 m
m = Mass of the Bicycle Rim = ?
Therefore,
<u>m = 1.99 kg = 2 kg</u>
Take for example driving by with a cake in your hand, then dropping it while going 30 mph. It will not drop directly down, it will gradually go in the direction you were driving while falling.
This is true I believe, if I'm interpreting correctly.
Formula unit is the empirical formula of an ionic or a covalent compound. It is the chemical formula that gives the proportions of the elements present in a certain compound however it does not give the actual numbers or the arrangement of the atoms. For this case, there are 14 atoms of different elements that is involved in the compound.
