The complete question is;
The gravitational force between two objects is ______ proportional to the products of the masses and _______ proportional to the square of the distance between them.
Answer:
First dash is directly
Second dash is inversely
Explanation:
From Newton's law of gravitation the gravitational force is given by the equation;
F = GMm/r²
Where:
F is gravitational force
M and m are two masses representing the two objects
r is the distance between them
G = universal gravitational constant
Thus, if we are to write it in proportion format, we will have;
F ∝ Mm/r²
From this proportion relationship, we can see that the Gravitational force is directly proportional to the products of the two masses and inversely proportional to the square of the distance between them.
Answer:
<em>10.09 units</em>
Explanation:
For the A
Ax = -8.0 units
Ay = 6.0 units
The resultant vector = Ra = 
Ra = 
= 10 units
For B
Bx = 1.0 units
By = -1.0 units
The resultant vector = Rb = 
Rb = 
= 
units
Adding these two vectors A and B together, magnitude of vector R is
R = 
R = 
= <em>10.09 units</em>
Put vinegar in a water bottle with no water, fill a balloon with baking soda, without pouring the baking soda in the vinegar put the balloon on the water bottle, then lift it so the baking soda goes in the vinegar, this will blow up the balloon
