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.
D) Sound waves carry energy parallel to the motion of the wave, while light waves carry energy perpendicular to it.
The momentum is 1.10×104×25=3850kgm/s
Answer:
3.51724 blocks
2.48275 blocks
Explanation:
L = Length of one block
t = Time taken by both person
Distance that I walk
The Distance that I will walk is 3.51724 blocks
Distance my friend will walk
Distance my friend will walk is 2.48275 blocks
Answer:
13kg
Explanation:
Force = Mass x Acceleration
26 = Mass x 2
divide both sides by 2
26/2 = Mass
13 = Mass
Mass is 13kg
