The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet.
Hey i am here to help you.
A: 2 concrete blocks 6cm apart will have the least gravitational attraction to each other.
I believe that this answer was helpful.
Answer:
P = 23400 [kg*m/s]
Explanation:
Momentum is defined as the product of force by the time of force duration. It can be determined by means of the following equation.
where:
P = momentum [kg*m/s]
F = force = 2600 [N]
t = time = 9 [s]
Now replacing:
![P=2600*9\\P=23400 [kg*m/s]](https://tex.z-dn.net/?f=P%3D2600%2A9%5C%5CP%3D23400%20%5Bkg%2Am%2Fs%5D)
We know, density = Mass / Volume
It represents density is directly proportional to mass and indirectly proportional to volume. So, at a constant volume, object with larger density will appear more heavier than that of object with smaller density.
In short, Heavier object will have the higher density than the other.
Hope this helps!
Answer:
a system of physical units ( SI units ) based on the metre, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten.
Explanation:
The problem here was not the error; it was the failure of NASA's systems engineering, and the checks and balances in our processes, to detect the error. That's why we lost the spacecraft.
