When a wire is heated, the current goes down from 0.3A to 0.26A. State how the resistance of the wire has changed
It's very wonderful to help you today!
Answer:
The resistance of the wire after being heated is approximately 1.15 times the resistance before being heated.
Explanation:
The resistance of the wire goes up as the temperature goes up.
By Ohm's law, we have the relationship between the resistance of a conductor R, the current flowing through it, I, and the voltage across it, V,
[tex]V=R~x~I[/tex]
As described, the current through the wire decreases so, to maintain the same voltage, the resistance must increase when the wire is heated. Let's say R1 is the resistance before heating the wire and R2 is the resistance after,
[tex]V=R_{1} x~I_{1} =R_{2}~} x~I_{2}[/tex]
Let's solve for R2,
[tex]R_{2} =\frac{I_{1} }{I_{2} }~x~R_{1}[/tex]
In this case, I1 = 0.3A and I2 = 0.26A,
[tex]R_{2} =\frac{0.3A}{0.26A} ~x~R_{1} =1.15R_{1}[/tex]
Hence, the resistance of the wire after being heated is approximately 1.15 times the resistance before being heated.

A student is investigating the distribution of charge in a conductor. He attaches two unopened soda cans on their sides to two foam cups with tape. He sets the soda cans with the cups onto a tabletop so that they are touching one another. Then he moves a negatively charged balloon close to the left soda can The set up for the investigation is shown above.
How do the electrons move in the soda cans?
A. They move to the bottom in both cans.
B. They move from the left can to the right can
C. They move to the top of both cans.
D. They move from the right can to the left can.
Answer:
Electrons repel one another - they will move "away" from the left side of the leftmost can- (the right can must become more negatively charged than the left can) -
B appears to be the best answer
The electrons move from the left soda can to the right soda can. The answer is (B).
When the negatively charged balloon is moved close to the left soda can, it will repel the negatively charged electrons in the soda can. This will cause the electrons to move away from the balloon and distribute themselves within the soda can.
Since the soda cans are in contact with each other, the excess electrons from the left soda can will be repelled by the negative charge on the balloon and will flow to the adjacent right soda can. The electrons will continue to move until there is no potential difference between the two cans, which means that they will stop flowing when both cans have the same amount of negative charge.

You want to cross a river that is 30 m wide and flows to the East at 3.0 m/s . You can swim at a speed of 5.0 m/s (relative to the water). If you start from the South side of the river and want to go straight across, at what angle should you point yourself
Answer:
Approximately [tex]\text{N$37^{\circ}$W}[/tex] (approximately [tex]37^{\circ}[/tex] west of north.)
Explanation:
The velocity of the swimmer relative to the water is given to be [tex]v(\text{swimmer})= 5.0\; {\rm m\cdot s^{-1}}[/tex]. Decompose this velocity into two components:
parallel to the flow of the river: [tex]v_{\parallel}(\text{swimmer})[/tex];perpendicular to the flow of the river: [tex]v_{\perp}(\text{swimmer})[/tex].Decompose the velocity of the current [tex]v(\text{current}) = 3.0\; {\rm m\cdot s^{-1}}[/tex] along the same set of directions.
parallel to the flow of the river: [tex]v_{\parallel}(\text{current}) = 3.0\; {\rm m\cdot s^{-1}}[/tex] to the east;perpendicular to the flow of the river: [tex]v_{\perp}(\text{current}) = 0\; {\rm m\cdot s^{-1}}[/tex] (Note that the current in the river flows along the river, not toward the banks of the river.)The velocity of the swimmer relative to the bank would be the vector sum [tex](v(\text{swimmer}) + v(\text{current}))[/tex]. Decompose this vector sum in the same directions:
parallel to the flow of the river: [tex]v_{\parallel}(\text{swimmer}) + v_{\parallel}(\text{current})[/tex];perpendicular to the flow of the river: [tex]v_{\perp}(\text{swimmer}) + 0\; {\rm m\cdot s^{-1}} = v_{\perp}(\text{swimmer})[/tex].Swimming straight across requires that the swimmer travel towards the banks but not along the banks. In other words, the velocity of the swimmer relative to the bank should be [tex]0[/tex] in the direction of the river: [tex]v_{\parallel}(\text{swimmer}) + v_{\parallel}(\text{current}) = 0[/tex].
Rearrange to obtain:
[tex]v_{\parallel}(\text{swimmer}) = -v_{\parallel}(\text{current})[/tex].
Thus, [tex]v_{\parallel}(\text{swimmer})[/tex] should be the exact opposite of [tex]v_{\parallel}(\text{current})[/tex].
Since [tex]v_{\parallel}(\text{current}) = 3.0\; {\rm m\cdot s^{-1}}[/tex] to the east, [tex]v_{\parallel}(\text{swimmer})\![/tex] should be [tex]3.0\; {\rm m\cdot s^{-1}\![/tex] to the west.
Refer to the diagram attached: [tex]v(\text{swimmer})[/tex] and its two components [tex]v_{\parallel}(\text{swimmer})[/tex] and [tex]v_{\perp}(\text{swimmer})[/tex] are the three sides of a right triangle, with[tex]v(\text{swimmer})= 5.0\; {\rm m\cdot s^{-1}}[/tex] as the hypotenuse.
Since the swimmer is travelling to the north, [tex]v_{\perp}(\text{swimmer})[/tex] would point northward.
The side [tex]v_{\parallel}(\text{swimmer})[/tex] would be opposite to the angle between the hypotenuse [tex]v(\text{swimmer})= 5.0\; {\rm m\cdot s^{-1}}[/tex] and north ([tex]v_{\perp}(\text{swimmer})[/tex],) Thus, the value of that angle would be:
[tex]\begin{aligned}& \arcsin\left(\frac{\text{opposite}}{\text{hypotenuse}}\right) \\ \\ =\; & \arcsin\left(\frac{3\; {\rm m\cdot s^{-1}}}{5\; {\rm m\cdot s^{-1}}}\right) \\ \approx \; & 37^{\circ}\end{aligned}[/tex].
Since [tex]v_{\parallel}(\text{swimmer})[/tex] points to the west, the direction of [tex]v(\text{swimmer})[/tex] would be approximately [tex]37^{\circ}[/tex] west of north, [tex]\text{N$37^{\circ}$W}[/tex].

Answer:
1. Option B
2. Option C
3. Option D
4. Option C
5. Option C
Explanation:
Given the following questions:
Question one:
Your answer is option B, a position time graph is one of the most common graphs to use to describe the motion of objects. The vertical line of the position time graph is the line that would be the y axis in some math cases. This line represents the "position of the object" or option B.
Question Two:
Your answer is option C or a "distance-time graph." The vertical axis shows the distance travels, while the horizontal line shows the time the object spends in the air. Distance-time graphs are used to show the distance an object traveled, in a certain amount of time.
Question three:
Your answer is option D or "shortest distance between two positions." Displacements definition is purely moving something from its initial position. Displacement is also seen as length and distance, which is why the shortest distance between two positions would be considered as true when it comes to displacement.
Question four:
Horizontal line would be the x-axis on a normal coordinate plane, since this is a distance-time graph and the horizonal line represents time. The answer will be option C or "object is accelerating." Since a distance-time graph shows how far an object goes in a certain amount of time, the horizontal line shows how fast the object is moving while traveling that distance within that certain amount of time.
Question five:
Your answer is option C or "X-axis: Time; Y-axis: Displacement." Since we are talking about a displacement-time graph, Y-axis is the dependent variable, it is what's being measured, so that would be displacement. While x-axis is the independent variable, which is what is being tested, so the x-axis will be time.

If runner A is running at 7.50 m/s and runner B is running at 7.90 m/s, how long will it take runner B to catch runner A if runner A has a
55.0-m head start?
Answer:
t= 137.5 s
Explanation:
So if we are wanting to figure out how long it takes runner B to catch runner A. we must first set the slope of each runner equal to one another
Slopes:
Runner A: y = 7.50x + 55
Runner B: y = 7.90 x
sooooo
7.50 x + 55 = 7.90 x
- 7.50 x - 7.50 x
55 = .40 x
55/.40 = .40 x / .40
x = 137.5 s
t= 137.5 s
7.50 * 137.5 + 55 =1086.25 m
7.90 * 137.5 = 1086.25 m
Runner B will catch Runner A after approximately 44.00 seconds.
To determine the time it takes for Runner B to catch Runner A, we need to consider their relative speeds and the initial distance between them.
Runner B is running faster than Runner A, so the distance between them will decrease over time. The relative speed of Runner B with respect to Runner A is the difference in their speeds:
Relative speed = Speed of Runner B - Speed of Runner A
Relative speed = 7.90 m/s - 7.50 m/s = 0.40 m/s.
Runner B needs to cover the initial distance (head start) of 55.0 meters between them. The time it takes for Runner B to catch up to Runner A can be calculated using the formula:
Time = Distance / Relative Speed.
Time = 55.0 m / 0.40 m/s = 137.5 seconds.
However, this time includes the time taken by Runner A to run the initial distance. To find the time taken by Runner B to catch Runner A after accounting for the head start, we subtract the initial time from the total time:
Time taken by Runner B = Total time - Time taken by Runner A.
Runner A's initial time = Distance / Speed = 55.0 m / 7.50 m/s = 7.3333 seconds.
Time taken by Runner B = 137.5 seconds - 7.3333 seconds = 130.1667 seconds.
Rounded to two decimal places, it takes Runner B approximately 130.17 seconds to catch up to Runner A.
