If this is a true/false question, then the above statement is false. Bowling balls may roll down hills, because they generally roll when used, but tennis balls do not roll. They are played with differently. So the statement is FALSE.
Explanation:
The gravitational force between two objects when they are placed at some distance is given by :
Where
G is universal gravitational constant
m₁ and m₂ are masses
d is the distance between masses
The gravitational force is directly proportional to the product of masses and inversely to the square of the distance between them. It would mean that if the mass of the objects increases, the force will increase while if the distance is increased, the force between objects will decrease.
Answer:
D. the dinosaurs appeared and came to dominate large-scale terrestrial life
Explanation:
The Mesozoic Era is a time in Earth history when
D. the dinosaurs appeared and came to dominate large-scale terrestrial life
The Mesozoic Era is the dinosaur age and lasted from approximately 250 to 65 million years ago for nearly 180 million years. This era includes three well-known periods called the periods of Triassic, Jurassic, and Cretaceous. A mass extinction marked the Mesozoic Era's beginning and end.
Answer:
Ok, so...... Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces. In the example below, the net force would be 900 Newtons (450 + 450 = 900), and the object would move to the right.
