<span>During their embryonic stage they have a flexible cord that supports their bodies which disappears in the adult stage. Some of these develop bones surrounding the cord in the adult stage rather than have it disappear.</span>
Qualitative, you don't have an actual numerical value but are making a conclusion based on observation.
Answer:
The final energy of the system is 168 J
Explanation:
Heat energy released to the surroundings,
Work done, W = 222 J
The initial internal energy,
The change in internal energy is given by the formula,
The final energy of the system is 168 J
The acceleration due to gravity of an object with a mass of 10000 g = 42.02 x 10^-16 m/s²
<h3>What is gravitational constant?</h3>
According to Sir Isaac Newton's rule of universal gravitation and Albert Einstein's theory of general relativity, the gravitational constant, indicated by the capital G, is an empirical physical constant that is used to calculate the gravitational effects.
<h3>According to the given information:</h3>
mass of object = 10kg
gravitational constant = 6.67 x 10^-11
radius of earth = 6.3 x 10^6
we know that:
acceleration due to gravity = GM/R²
= ((6.67 x 10^-11)*10)/(6.3 x 10)²
Solving this we get :
42.02 x 10^-16 m/s²
The acceleration due to gravity of an object with a mass of 10000 g = 42.02 x 10^-16 m/s²
