A possible effect is the risk of Icecaps melted
Answer:
The phenomenon of diffraction.
Explanation:
Diffraction of light that resembles the behavior of waves in water made scientists think that light have a wave nature.
Answer:
Explanation:
F = GmM/d²
As gravity force is proportional to the inverse of the square of the distance,
doubling the distance will reduce the weight to a forth.
F' = GmM/(2d)²
F' = ¼GmM/d²
F' = ¼F = ¼(4000)
F' = 1000 N
Answer:
Explanation:
The total kinetic energy of both electrons will be electrostatic potential energy, when the electrons reach the minima distance due to electrostatic repulsion. Then, you have:
me: mass of the electron
q: charge of the electron
k: Coulomb's constant
you take into account that v2=3v1=3v and do rmin the subject of the formula:
Answer:
12.46 joules
Explanation:
The formula of potential energy is:
where m is mass, g is gravitational force (9.8 m/s^2) and h is height.
- Mass is given to be 2.3 grams.
- Gravitational Force is defined as 9.8 m/s^2.
- Height is given as 553 meters.
However, mass must be in kilograms (kg) unit so we will be converting the gram to kilogram:
We know that a gram equals to 0.001 kg so 2.3 grams will equal to 2.3 * 0.001 = 0.0023 kg.
Therefore, substitute known information in the formula of potential energy:
Therefore, the potential energy is 12.46 joules.
