What i would say: The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Hope this helps! :)
Solid water is less dense than liquid water.
Answer:
0.50 mol
Explanation:
The half-life is <em>the time required for the amount of a radioactive isotope to decay to half that amount</em>.
Initially, there are 8.0 moles.
- After 1 half-life, there remain 1/2 × 8.0 mol = 4.0 mol.
- After 2 half-lives, there remain 1/2 × 4.0 mol = 2.0 mol.
- After 3 half-lives, there remain 1/2 × 2.0 mol = 1.0 mol.
- After 4 half-lives, there remain 1/2 × 1.0 mol = 0.50 mol.
Answer:
The answer to your question is Power = 0.98 W or 9.8 x 10⁻⁴ kW
Explanation:
Data
Power = ?
mass = 100 g = 0.1 kg
distance = 1 m
gravity = 9.8 m/s²
Formula
Power = Work / time
Process
1.- Calculate the Work
Work = Force x distance
Force = mass x gravity
Work = mass x gravity x distance
Work = (0.1 kg)(9,8)(1)
Work = 0.98 J
2.- Calculate the power
Power = 0.98 J / 1 h
Power = 0.98 W or 9.8 x 10⁻⁴ kW
It can form long chains, unlike any other element
It is found in every life-related chemical
