incorrect
1.
Faraday's law
incorrect
2.
newtons first law of motion
incorrect
3.
kirchoffs law
incorrect
4.
newtons second law of motion
incorrect
5.
universal law of gravitation
incorrect
6.
newtons third law of motion
A.
For every action there is an equal and opposite reaction.
B.
a changing magnetic field induces a changing electric field. the fields are both proportional& perpendicular
C.
series- current is constant & voltage divides unevenlyparallel- voltage is current ¤t divides
D.
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector
E.
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
F.
every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them
Type the Question that corresponds to the displayed Answer.
incorrect
7.
the change in frequency of a wave for an observer moving relative to the source of the wave
incorrect
8.
is the rate at which work is performed or energy is converted
incorrect
9.
the universe begin as a singularity not an atom that contained all the mass of the entire universe in zero space
incorrect
10.
Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere
incorrect
11.
any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity
incorrect
12.
a changing electric field induces a changing magnetic field. the fields are both proportional& perpendicular LIGHT!
incorrect
