As resistance increases in a circuit, the current flowing through the circuit decreases.
This is because resistance opposes the flow of current, so as resistance increases, it becomes more difficult for the current to flow.
This is described by Ohm's Law, which states that the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance.
Therefore, as resistance increases, the current must decrease in order to maintain the same voltage in the circuit.

A magnet is an item or substance that generates a magnetic field. The broken pieces of the magnet will have 4 poles.
A magnet is an item or substance that generates a magnetic field. This magnetic field is invisible, but it is responsible for a magnet's most remarkable property: a force that attracts or repels other ferromagnetic elements such as iron, steel, nickel, cobalt, and others.
When a magnet is broken into two pieces, it produces two complete magnets, each with its own north and south poles and the same orientation as the original.
For example, if you break a 12-inch bar magnet with N on the left end and S on the right end midway between the two ends, you'll get two magnets with N on the left end and S on the right end, as seen in the illustration below.
Hence, the broken pieces of the magnet will have 4 poles.

Technically, there is not enough information to tell, because in your picture, you cut off the last word in the question.
If the last word in the question is "acceleration", then "C" is the correct choice.
If some other word is the last one in the question, then it has to be "D".
Answer:
D. there is not enough information to tell
Explanation:
I have already read this in grade five
Considering the definition of percentage by mass, the percent by mass of 5.0 g of iron (II) sulfate dissolved in 75.0 grams of water is 6.25 %.
The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.
In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.
The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:
In this case, you know:
Replacing:
Solving:
percent by mass= 6.25 %
Finally, the percent by mass of 5.0 g of iron (II) sulfate dissolved in 75.0 grams of water is 6.25 %.

Hello!
What the percent by mass of 5.0 g of iron (II) sulfate dissolved in 75.0 g of water?
We have the following data:
m1 (solute mass - iron II sulfate) = 5.0 g
m2 (solvent mass - water) = 75.0 g
m (solution mass) = m1 + m2 = 5.0 + 75.0 = 80.0 g
%m/m (percent mass by mass) = ?
We apply the data to the formula
Answer:
The percent by mass of solute and mass solution of Iron II Sulfate is 6.25%
