m₁ = mass of the first object = 3.0 kg
m₂ = mass of the second object = 3.0 kg
r = distance between the first and second object = 1.0 m
G = universal gravitational constant = 6.67 x 10⁻¹¹ N m²/kg²
F = force of gravity between the two objects = ?
according to law of gravitation, force of attraction "F" between two objects m₁ and m₂, placed distance "r" apart is given as
F = G m₁ m₂/r²
inserting the values
F = (6.67 x 10⁻¹¹) (3.0) (3.0)/(1.0)²
F = (6.67 x 10⁻¹¹) (9.0)
F = 60.03 x 10⁻¹¹ N
F = 6.003 x 10⁻¹⁰ N
<h2>Answer: in a gaseous state
</h2>
The average kinetic energy of the water molecules is greater in its gaseous state (in the form of water steam).
This is because in the gaseous state the water molecules are well separated from each other and can move freely in all the available space they have; because there are no cohesion forces that bond them.
In contrast to the liquid and solid state, in which the molecules have less movement.
Use the formula
Heat= mass x specific heat x temperature increase
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.
