Answer:
The mass of Neptune is kilograms.
Explanation:
From Newton's Law of Gravitation, the gravitational acceleration of Neptune is determined by the following formula:
(1)
Where:
- Gravitational constant, measured in cubic meters per kilogram-square second.
- Mass of the planet, measured in kilograms.
- Radius of the planet, measured in meters.
- Gravitational acceleration, measured in meters per square second.
If we know that , and , then the mass of Neptune is:
The mass of Neptune is kilograms.
The correct answer is "wavelength".
In fact, the wavelength of a wave corresponds to the distance between two consecutive same-shape points of the wave: for instance, the distance between two consecutive crests, or the distance between two consecutive throughs.
For the wave in this problem, t<span>he distance between two consecutive crests is 2.5 meters, therefore the wavelength of the wave is 2.5 m.</span>
Answer:
Explanation:
Ike will need to bring positively charged object near one end of the tape, electrons in the tape act like a conductor and will be attracted to the end near the positively charged object. This leaves the other end of the tape positively charged as a result of induction. Therefore, when Ike touch the positive end of the metal rod, electrons from his body will be attracted to the positive rod and transfer onto the rod. When he remove his finger, the rod has more electrons and is will be negatively.
