Answer:
Petametres; 41 Pm
Explanation:
A measurement should use units that give a number between 0.1 and 1000.
The measure that astronomers use is the light year — the distance that light travels in one year.
In those units, the distance is 4.3 light years.
We can calculate the distance in SI units.
In SI, we should measure the distance in petametres (1 Pm = 10¹⁵ m)
Thus, the distance to the nearest star is 41 Pm.
Answer:
Hey
The Gravitational force from the moon and the sun are aligned with the equator, if a sateite were to orbit horizontally it would quickly come out of sync.
The transfer of heat that utilizes or occurs in the form of wave, would be B. Radiation. As heat, can be emitted in the form of waves which constitute or make up the electromagnetic spectrum, specifically these include UV Rays from the sun for instance.
To solve this problem we will apply the concepts related to the Force based on pressure and temperature. Initially we will start from the definition of pressure that warns that it is the equivalent to the force applied to the unit of area, or any of those derived from this relationship. Subsequently, through the gas pressure-temperature ratio equations, we will set the desired pressure. The equation relating force and pressure is
The value of final pressure is calculated as follows
Therefore the value of force is
Replacing,
Therefore the force due to the internal air pressure on each wall of the box is 5.1kN
