Answer:
Density = 3 x 10⁻⁵ kg/m³
Explanation:
First, we will find the volume of the planet:
Now, we will use the expression for gravitational force to find the mass of the planet:
where,
m = mass = ?
g = acceleration due to gravity = 6.67 x 10⁻¹¹ m/s²
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²
r = radius = 8000 m
Therefore,
Therefore, the density will be:
<u>Density = 3 x 10⁻⁵ kg/m³</u>
Because she fell out of a tree
Answer:
Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.
Explanation:
The reaction of the half-life is a description of the needed time for the reactant to deplete.In the first order reactions formula, k is considered as the first order rate constant whose unit is denoted as 1/s. Hope this helps.
