The answer is D. A more reactive metal replaces a less reactive metal in a chemical reaction.
A current carrying wire is placed vertically. The magnetic field around the wire is rotating clockwise around the wire. The current is moving from top to bottom
Holding a current carrying wire in your right hand with the thumb pointing in the direction of current flow, the fingers wrapping the wire will portray the magnetic lines of force direction, following the right-hand thumb rule.
As a result, a current carrying conductor is vertically held. If you follow the rule, the current should be passed through it to generate a clockwise magnetic field around the conductor from top to bottom.

Answer:
4.12 m/s^2
Explanation:
unbalanced force means the presence of resultant force (net force)
f = 28N
m = 6.8kg
a = ?
? = 28/6.8
= 4.1176...
approximately = 4.12 m/s^2
Answer:
Alburt Bandura
Explanation:
Rosalind has learned to be impulsive and seldom waits for her turn when playing with other children, this trait she has learned from her father, who is also an impulsive man.
The theorist who would most likely suggest that Rosalind has learned to be impulsive from watching her father is Alburt Bandura. Alburt in his famous Bebo Doll experiment confirmed that children learn from the adults behavior in their life.
Answer:
False
Explanation:
No, it is not true that energy of the electrons ejected should have been proportional to the intensity of the light. Perhaps the kinetic energy of the ejected electrons is independent of the intensity of the incident radiation. This is the very fact that classical theory of electromagnetism fails to explain in photoelectric effect. The kinetic energy of the electrons remains constant even if the amplitude of the incident light is increased.
