The answer to your question is,
A scientific law.
-Mabel <3
The formula is M=Fd
so we have F=84N and d=0.25m
Now we just replace F and d into the formula M=84N×0.25m
And the last thing we do is calculate it
M=21Nm
Since the table does not accelerate, the upward and downward forces must cancel. Since the downward force of the table legs on the ground is the weight of the table and the book, 175N, this is also the force the pushing up on the table legs by the floor.
<u>Answer:</u>
The altitude of planet = 5989.198 km
<u>Explanation:</u>
We know that centripetal acceleration, 
, where v is the velocity and r is the radius. In this case both acceleration and velocity is given, so we can find radius of satellite.
v = 
a = 
So, 
We have diameter of earth = 12713 km
Radius of earth = 12713/2 = 6356.5 km
The altitude of planet = Radius of planet - radius of earth
= 12345.698 - 6356.5
= 5989.198 km
Desert pavement or commonly called stone or stony pavement is a type of desert surface that is covered with pebbles and stone tight and intertwined. Many of these layers form a type of pavement known as mosaic. When the particles begin to be stacked between different natural agents such as rain, gravity and animals compact the layers and generates a layer that allows the pavement not to erode. Basically runoff and deflation eliminate silt and clay, leaving thicker particles behind.
The correct answer is A.
