Answer:
1327 kg
Explanation:
So the net force exerted on the wagon would be the sum of forces from 2 horses subtracted by friction force
This force results in an acceleration of a = 1.3 m/s2. We can use Newton's 2nd law to calculate the mass of the wagon
Answer:
C
Mass is directly proportional to the Force of Gravity. If Mass increases, then the Force of Gravity increases; however, Distance is indirectly (or inversely) proportional to the Force of Gravity. If Distance increases, then the Force of Gravity decreases.
Explanation:
The formula for the force of gravity between two objects is
where
G is the gravitational constant
m1, m2 are the masses of the two objects
d is the separation between the two objects
We notice the following:
- F is directly proportional to the masses, . This means that if one of the masses increases, then the force between them, F, increases in a proportional way
- F is inversely proportional to the square of the distance, . This means that if the distance between the two objects is increased, the force between them will decrease, and vice-versa.
So, the correct answer is
C
Mass is directly proportional to the Force of Gravity. If Mass increases, then the Force of Gravity increases; however, Distance is indirectly (or inversely) proportional to the Force of Gravity. If Distance increases, then the Force of Gravity decreases.
