The diagrams below show the number of thumbtacks that were picked up by four magnets.
Magnet A
Magnet B
Magnet C
Magnet D
Sonia, Clara, Freida and Beverly made the following conclusions based on the
diagrams above:
Sonia: A bigger magnet has a stronger pull.
Clara: A smaller magnet has a stronger pull.
Freida: The strength of a magnet depends on its size.
Beverly: The strength of a magnet does not depend on its size.
Who made the correct conclusion?​

Examine the nuclear reacti why is this classified as a nuclear reaction rather than a chemical reaction? it is not balanced. a new compound is formed. a change has occurred in a nucleus. a new element has been formed.

Acapacitor is storing energy of 3 joules with a voltage of 50 volts across its terminals. a second identical capacitor of the same value is storing energy of 1 joule. what is the voltage across the terminals of the second capacitor?

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
