Answer:
This show the most stable of atom of that element
Explanation:
The mass number of a element on the periodic table show the most stable atoms of that element.
Answer:
the answer is letter d because both of them are pushing the couch in the same direction so 4 plus 2 will give you 6N
Answer: clay
Explanation:
Florida is mainly influences by Spanish culture, so building with clay and wood would make sense, knowing that that is how pueblas are built.
Answer:
-150 N
Explanation:
(Newton's second law) F=ma
Sum of forces in Y direction= (+200 N)+(-200 N)= 0...
forces cancel, object does not accelerate up/down
Sum of forces in X direction= (+65 N)+(-65 N)+(-150 N)
= -150 N
notice that the +/- 65 components cancel, leaving a net force of 150 N in the LEFTwards direction (which is typically defined as negative)
Overall, the net force is -150 N
Answer:
Amount of linear movement
Explanation:
Our system is defined by the rate of change in mass that
leaves the car 
, this happens during a time interval
![[t, t + \Delta t]](https://tex.z-dn.net/?f=%5Bt%2C%20t%20%2B%20%5CDelta%20t%5D)
, in addition to freight car and sand at time t.
In this way we need to define the two states:
State 1,
consider 
and V.
State 2,
consider 
In this state is the mass of sand output, which
is composed of
In this way we define the Linear movement in x, like this:
In this way we proceed to obtain the Force
Since the mass of the second term becomes 0, the same term is eliminated, thus,
