Answers
In a purely resistive alternating-current circuit, the current and voltage are in phase. AC circuit, the current and voltage are in phase, exhibiting the same timing for their zero and peak values
However, in a purely resistive circuit, where the only component is a resistor, the current and voltage are in phase. This means that they both reach their zero and peak values at the same time during each cycle of the alternating current.
In a resistive circuit, the voltage across the resistor is directly proportional to the current flowing through it, according to Ohm's Law (V = IR). Since there is no phase difference between the current and voltage, they rise and fall together. When the current is at its peak value, the voltage across the resistor is also at its peak value. Similarly, when the current is zero, the voltage is also zero.
This behavior occurs because a resistor dissipates energy in the form of heat and does not store energy or introduce any phase shifts. Therefore, in a purely resistive AC circuit, the current and voltage are in phase, meaning they both reach their zero and peak values at the same time.

\(\mathrm{ \#TeeNForeveR}\)
Answer:
0.078 inches
Explanation:
The volume of a cylinder is \(V=\pi r^{2} h\). \(r\) is the radius of the cylinder, \(h\) is the height of the cylinder, and \(V\) is the total volume.We can divide both sides by \(9\pi\) to isolate the height. We now have \(\frac{220}{9\pi }=h\).We can plug in \(220\) for the value of \(V\), and insert 3 as \(r\). Now, we have \(220 = \pi (3^2)(h)\).We can simplify the right side by finding the value of \(3^2\), which is \(3*3\), or \(9\). We now have \(220 = 9\pi h\).Divide both sides by \(9\pi\) so we can isolate the height! We now have \(\frac{220}{9\pi }=h\).It would be best to use a calculator at this point. Plug the above equation into a calculator; otherwise, replace \(\pi\) with \(3.14\) and simplify the fraction. You should get about \(07.7809...\) which we can round to the nearest hundredths (since this is Geometry, I am assuming you know how to round).Our final answer is \(07.78\) inches.Hopefully this was of use!

use the sliders to change the mass and the volume of the wood block. can you change whether the wood block floats or sinks without changing the material? explain your reasoning.
Answers
Yes, it is possible to change whether the wood block floats or sinks without changing the material. This is because the buoyancy of an object is determined by the density of the object compared to the density of the fluid it is in. If the density of the wood block is less than the density of the fluid it is in, it will float.
Conversely, if the density of the wood block is greater than the density of the fluid it is in, it will sink. By adjusting the mass and volume of the wood block using the sliders, you can change the density of the block and thus change whether it floats or sinks. For example, by decreasing the mass or volume of the wood block, you can decrease its density and make it more likely to float.
"Can you change whether the wood block floats or sinks without changing the material?" using the sliders for mass and volume:
Yes, you can change whether the wood block floats or sinks by adjusting the mass and volume of the block without changing the material. The key factor that determines if an object floats or sinks is its density, which is the mass divided by the volume (density = mass/volume).
Step 1: If you increase the mass of the wood block while keeping the volume constant, you will increase its density.
Step 2: Compare the density of the wood block with the density of the liquid it is placed in.
Step 3: If the density of the wood block is greater than the density of the liquid, the block will sink. Conversely, if the density of the wood block is less than the density of the liquid, the block will float.
By changing the mass and volume sliders, you can alter the density of the wood block and ultimately affect its buoyancy without changing the material it is made of.

a motorcycle covers a distance of 8.5 km in 15 minutes. Calculate the distance covered by the motorcycle in per second
Answers
1min=60sec
15min=60•15
15min=900sec
Now, let’s create a ratio. We want to find the unit rate (most simplified rate) of distance covered by the motorcycle.
Recall that d=s•t, where d=distance, s=speed, and t=time.
So, we know the distance is d=8.5 and the time is t=900sec, but we need the speed (“s”)
8.5km=(900sec)•s
Divide both sides by 900:
8.5km/900sec=s
.009km/sec=s

According to Coulomb's law, when the distance between two point charges doubles, what happens to the electric force acting between the charges? It goes down by a factor of 4 It stays the same It goes up by a factor of 2 It goes down by a factor of 2.
Answers
According to Coulomb's law, when the distance between two point charges doubles, the electric force acting between the charges goes down by a factor of 4.
Coulomb's law states that the magnitude of the electric force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, it can be expressed as:
\(\[ F = k \cdot \frac{q_1 \cdot q_2}{r^2} \]\)
where \(\( F \)\) is the electric force, \(\( q_1 \)\) and \(\( q_2 \)\) are the charges of the two point charges, \(\( r \)\) is the distance between them, and \(\( k \)\) is the electrostatic constant.
When the distance \(\( r \)\) between the charges doubles, it becomes \(\( 2r\)). Substituting this value into the equation, we get:
\(\[ F' = k \cdot \frac{q_1 \cdot q_2}{(2r)^2} = k \cdot \frac{q_1 \cdot q_2}{4r^2} = \frac{1}{4} \left( k \cdot \frac{q_1 \cdot q_2}{r^2} \right) = \frac{1}{4} \cdot F \]\)
Therefore, the electric force acting between the charges goes down by a factor of 4 when the distance between them doubles.

What part of the fluid mosaic model is hydrophilic?
Answers
In the fluid mosaic model of the cell membrane, the hydrophilic (water-loving) part is the outer layer, also known as the "heads" of the phospholipid molecules that make up the membrane.
Hydrophilic is a term used to describe a substance or a part of a molecule that has an affinity or attraction to water molecules. Hydrophilic substances are typically polar or charged, which allows them to form hydrogen bonds with water molecules.
These heads contain a polar, hydrophilic phosphate group and are attracted to water molecules, which allows them to interact with the aqueous environment both inside and outside the cell. The hydrophilic heads face towards the aqueous environments, while the hydrophobic tails face away from the aqueous environments, creating a bilayer structure that is characteristic of the cell membrane.

Answers
This problem involves a person standing on a rotating platform and holding a spinning bicycle wheel.
The moment of inertia of the person plus platform is given as IP and the moment of inertia of the wheel is given as IW with an angular velocity of ωW. The problem asks for the angular velocity ωP of the platform when the person moves the axis of the wheel to various positions and also when the person stops the wheel.
Part A: When the axis of the wheel is moved vertically upward, the angular momentum of the system is conserved, but the moment of inertia changes due to the change in orientation of the wheel. The new moment of inertia is IP + IW. Therefore, the angular velocity ωP of the platform is given by ωP = (IWωW) / (IP + IW) which is zero when the wheel is in the vertical position.
Part B: When the axis of the wheel is moved to a 60∘ angle to the vertical, the new moment of inertia becomes IP + (IW/4). Therefore, the angular velocity of the platform becomes ωP = (4IWωW) / (4IP + IW).
Part C: When the axis of the wheel is moved vertically downward, the new moment of inertia is IP + IW. The angular velocity of the platform becomes ωP = (-IWωW) / (IP + IW).
Part D: When the person reaches up and stops the wheel in part A, the platform becomes ωP = (-IWωW) / (IP + IW).new angular momentum of the system becomes zero. Therefore, the angular velocity of the platform becomes ωP = (-IWωW) / IP.
