Gravitational pull between 2 objects is determined by which of the following?
2 answers:
Answer:
Both distance between and mass of the 2 objects
Explanation:
The gravitational pull between two objects is given by:
where
G is the gravitational constant
m1 is the mass of the first object
m2 is the mass of the second object
r is the distance between the two objects
From the formula, we see that the gravitational pull depends both on the distance between the two objects (r) and on their masses (m1, m2), so the correct answer is
Both distance between and mass of the 2 objects

Answer:
a) ω1 = 18rpm ω2 = -18rpm
b) ω1 = 102rpm ω2 = 138rpm
c) ω1 = ω2 = 3.18rpm
Explanation:
For the first case, we know that each wheel will spin in a different direction but with the same magnitude, so:
ωr = 6rpm This is the angular velocity of the robot
where D is 30cm and rwheel is 5cm
One velocity will be positive and the other will be negative:
ω1 = 18rpm ω2 = -18rpm
For part b, the formula is the same but distances change. Rcircle=100cm:
Replacing values, we get:
For part c, both wheels must have the same velocity:
