Answer:
Suppose any object with mass in our planet.
The object will be affected by the gravitational force, that pulls the object down. Now, a table in your dining room is also affected by this force, but the table is in a surface (the ground) and it does not move.
We know that if an object does not move, then the net force acting on it is equal to zero, this means that there is a force equal and opposite ot the gravitational force.
This force is the normal force, that the ground applies on the table. This force comes as a "response" to the table pushing the ground (By 3rd Newton's law).
So two forces that are always equal and opposite are the forces caused by this law.
Answer:
Explanation:
Una magnitud fundamental es aquella que se define por si misma y es independiente de las demás (masa, tiempo, longitud, etc.). magnitud derivada. Una magnitud derivada es aquella que se obtiene mediante expresiones matemáticas a partir de las magnitudes fundamentales (densidad, superficie, velocidad).
Answer:
The value of mass 1, m1= 6/5m
The value of mass 2, m2= 3/5m
Explanation:
case 1:
here tension and the acceleration will be:
for m1;
- mg-T=ma
- 2mg - 2T = 2ma .....1.
for m2:
adding the both equations,
2mg - 2T + 2T-mg = 2ma + ma/2
a = 2/5 g
putting the value of a into the equation 1.
mg - T = m* (2/5)g
T = 3/5 ( mg )
now
case 2:
The two identical blocks are released from the rest, the tension remains the same as the case 1.
so,
for m1:
for m2:
adding both equations we get,
2T-m2g + 2m2g - 2T = 0
m2 = m1 / 2
T = m1*g / 2
here we know that
T (case1) = T (case2)
3/5 ( mg ) = m1*g / 2
m1 = 6/5 m
hence
m2 = 3/5 m

Nurture refers to all the environmental variables that impact who we are, including our early childhood experiences, how we were raised, our social relationships, and our surrounding culture
While certain physical traits like skin and eye color and diseases like sickle cell anemia and Huntington’s chorea have been found to be the result of direct genetic inheritance, virtually any pattern of thinking or behavior can be understood from the perspective of a combination of nature and nurture. In the animal kingdom, domestication of many species is understood to be the result of encouraging domesticated behaviors (nurture), then having animals that most successfully adopt those behaviors breed with each other so it becomes part of their nature (Bouchard, 1994).
In humans, many studies in more than the past 20 years involve identical or fraternal twins who are separated at birth. The question of nature vs. nurture somewhat continues to be debated concerning human behavior, intelligence, and in the development of personality traits
hi <3
the correct option would be A. displacement. displacement is distance in a direction
hope this helps :)
