Answer:
Gravitational potential energy stored is 9.8 J.
Given:
G = 9.8
height = 0.5 m
mass = 2 kg
To find:
Gravitation Potential energy stored = ?
Formula used:
Potential energy = mGh
m = mass
G = acceleration due to gravity
h = height
Solution:
Potential energy of the object is given by,
Potential energy = mGh
m = mass
G = acceleration due to gravity
h = height
Potential energy = 2 × 9.8 × 0.5
Potential energy = 9.8 Joule
Gravitational potential energy stored is 9.8 J.
Answer:
Explanation:
One mole of a substance contains the same amount of representative particles. These particles can be atoms, molecules, ions, or formula units. In this case, the particles are atoms of titanium.
Regardless of the particles, there will always be <u>6.02*10²³</u> (also known as Avogadro's Number) particles in one mole of a substance.
Therefore, the best answer for 1 mole of titanium is D. 6.02*10²³ atoms.
