Suppose you have two magnets. Magnet A doesn't have its poles labeled, but Magnet B does have a clearly labeled north and south

pole. If these two are brought into contact with one another, which of the following could you expect?
A. The side of Magnet A that's attracted to Magnet B's north pole must be Magnet A's north pole.
B. The side of Magnet A that's repelled by Magnet B's south pole must be Magnet A's north pole.
C. The side of Magnet A that's attracted to Magnet B's south pole must be Magnet A's north pole.
D. The side of Magnet A that's repelled by Magnet B's north pole must be Magnet A's south pole

Like poles of 2 magnets Repel each other and unlike poles attract each other. so the answer would be C. the side of magnet A that's attracted to Magnet B's South pole must be Magnet A's North pole.

<span>The right answer here would be option C - the side of Magnet A that's attracted to Magnet B's south pole must be Magnet A's north pole. This is due to the magnetic rule of opposites attracting.</span>

A sample contains 20 kg of radioactive material. The decay constant of the material is 0.179 per second. If the amount of time t
Nataly [62]

Answer:

Explanation:

Given

N0 = 20kg (original substance)

decay constant λ = 0.179/sec

time t = 300s

We are to find N(t)

Using the formula;

n(t) = N0e^-λt

Substitute the given values

N(t) = 20e^-(0.179)(300)

N(t) = 20e^(-53.7)

N(t) = 20(4.7885)

N(t) =143.055

To know how much of the original material that is active, we will find N(t)/N0 = 143.055/20 = 7.152

About 7 times the original material is still radioactive

Which has the greater acceleration
Alik [6]
Answer: Object B

The velocity of object A is depicted in the graph as a straight line (constant speed therefore no acceleration).
The graph indicates that the velocity of object B increases (the object is accelerating).

What is the difference in electrical potential energy between two places in an electric field?
Phoenix [80]

Answer: Option (c) is the correct answer.

Explanation:

The difference in electrical potential energy between two places in an electric field is known as potential difference.

Mathematically, potential difference between two given points can be written as follows.

             \Delta V = V_{2} - V_{1}

where,    \Delta V = potential difference

              V_{1} = potential at point 1

               V_{1} = potential at point 2
