Answer:
2.12/R mW
Explanation:
The electrical power, P generated by the rod is
P = B²L²v²/R where B = magnetic field = 0.575 T, L = length of metal rod = separation of metal rails = 20 cm = 0.2 m, v = velocity of metal rod = 40 cm/s = 0.4 m/s and R = resistance of rod = ?
So, the induced emf on the conductor is
E = BLv
= 0.575 T × 0.2 m × 0.4 m/s
= 0.046 V
= 46 mV
The electrical power, P generated by the rod is
P = B²L²v²/R
= B²L²v²/R
So, P = (0.575 T)² × (0.2 m)² × (0.4 m/s)²
= 0.002116/R W
= 2.12/R mW
Imagine a block with A pulling one way and B the other.
If A is bigger than B then obviously it will go in the direction of A.
The net force will be A-B as A is pulling it along with x but b is also pulling back with y.

Answer:
A) attachment.
Explanation:
The psychiatrist and psychoanalyst John Bowlby (1907 - 1990) believed that the causes of mental health and behavioral problems could be attributed to early childhood. In fact, John Bowlby's <u>attachment theory states that we have been biologically preprogrammed to build bonds with others and that they help us survive.
</u>
Bowlby was greatly influenced by ethological theory in general, but above all by Konrad Lorenz's study of the imprint done with ducks and geese in the 50s. From this, Lorenz demonstrated the survival value of the attachment bond by Your innate character
Thus, Bowlby thought that attachment behaviors were instinctive and that, in addition, their activation depended on any condition that could threaten the achievement of proximity, such as separation, insecurity or fear.
John Bowlby's attachment theory defends that children are biologically programmed to form bonds with others.
Answer:
Push because the force you use up is greater then down
