Assuming the same current is running through two separate coils, why is it easier to thrust a magnet into a wire coil with one loop than one with four loops?.

Answer:

To decrease the current;

1) Use fewer loops or number of turns

2) Use a lower speed of rotation of the coil in the magnetic field

3) Use a weaker magnetic

Explanation:

According to Faraday's Law of induction, which is the basis of the electromagnetism, electromagnetic induction and therefore the basis of the  electric generator, can be written as follows;

Where;

ε = The induced voltage

N = The number of turns (loops)

ΔФ = The change in the magnetic flux

Δt = The change in the time (the duration)

Given that voltage is directly related to the current, decreasing the voltage, decreases the current

To decrease the voltage, and therefore, the current we can;

1) Reduce the number of loops in the coil

2) Increase the time change per unit change in flux by slowing down the speed of rotation of the generator

3) Decrease the amount of change in the magnetic field per turn, by using a weaker magnetic

B) Moving with zero acceleration.

Explanation:

Acceleration is defined as the rate of change of the velocity per unit time:

In a velocity-time graph, this ratio corresponds to the slope of the curve. In fact:

(change in velocity) corresponds to the increase in the y-axis

(change in time) corresponds to the increase in the x-axis

So, acceleration corresponds to the slope of the curve in a velocity-time graph. For cart C, the slope is zero, therefore the acceleration is also zero.

Answer:

B) Moving with zero acceleration.

Explanation:

As we can see the graph for Cart C that its velocity is constant and not changing its magnitude as well as its sign

So here the magnitude and direction is constant so we can say that velocity will remain constant always.

Where we can define the acceleration as

so here if magnitude and direction both are constant so

so we can say that acceleration of cart C is ZERO

so correct answer will be

B) Moving with zero acceleration.

Final answer:

Generally, as temperature rises, solid solubility increases while gas solubility decreases. This is why when a carbonated drink gets warm, it has less bubbles.

Explanation:

Generally, as the temperature increases, the solubility of solids typically increases, while the solubility of gases usually decreases. Thus, for Ava's case with the beverage, as the drink got warmer (indicating an increase in temperature), the bubbles, which are gaseous, decreased. A real-life example of this is a carbonated drink. When you open a cold soda, it starts out very bubbly.

However, if you let it sit and warm up, the gas (carbon dioxide) becomes less soluble in the liquid and leaves the solution, resulting in fewer bubbles.
