Voltage drop is a better measurement of resistance than testing static resistance because: current flow creates heat which adds to circuit resistance
The current flow or electric current is the measure of the electrons flow around a circuit. It is measured in amperes or "amps". If the current is higher the electrons flow is greater.
The course of a conventional electric current in the external circuit is directed away the positive terminal and toward the negative terminal of the battery

A labrador retriever runs 50.0 meters in 7.20 seconds to retrieve a bird. the dog then runs half way back in 3.85 seconds. determine the average speed of the dog and the average velocity of the dog
The average speed of the dog is 6.8 m/s while the average velocity is 6.8 m/s halfway to the starting point.
Speed and velocityThe speed of a moving object is the ratio of the distance covered by the object and the time taken to cover the distance. The average speed is the ratio of the total distance traveled and the total time taken.
Velocity, on the other hand, refers to the speed in a particular direction. In other words, velocity is a vector quantity while speed is a scalar quantity.
In this case:
Total distance covered = 50 + 25
= 75 meters
Total time taken = 7.2 + 3.85
= 11.05 seconds
Average speed = 75/11.05
= 6.8 m/s
Average velocity = 6.8 m/s halfway

A father and his young daughter are ice skating. they face each other at rest and push each other, moving in opposite directions. which one has the greater final speed? group of answer choices
A father and his young daughter are ice skating. According to it, the daughter has greater speed.
The law of action and response is Newton’s third principle.According to Newton’s third law, when two bodies come into contact, they exert forces on one another that are equal in size and directed in the opposite direction. The law of action and reaction is another name for the third law.
This law applies to bodies in uniform or rapid motion and is crucial for addressing problems of static equilibrium, where all forces are in balance. The forces it discusses are actual phenomena, not just accounting tricks.
If there is a net force operating on a body, it moves faster in line with the second rule.
If there is no net force acting on the body, either because there are no forces at all or because all forces are precisely balanced by opposing forces, the body does not accelerate and is said to be in equilibrium.
On the other hand, it can be assumed that a body that appears to be moving slowly has no net force acting on it.
So going according to it, the daughter has greater speed.

what is sound and how does it move through different mediums?
In a first order decomposition, the constant is 0.00586 sec-1. what percentage of the compound is left after 3.32 minutes?
The correct answer for percentage of the compound is left after 3.32 minutes is 55 % .
We use the formula A(t) = A0e-kt for decomposition, where A0 is the initial amount of decomposed substance at t = 0, k is the decay constant, t is the time elapsed, and A(t) is the amount after time t.
The percentage of decomposed compound left after a time t is, [A(t)], divided the the initial amount, [A0], time 100, or A/A0*100:
A = A0e-kt
A/A0 = e^- 0.00586t, [k = 0.00299, divide both sides by A0]
A/Ao = e^(-0.00299*199), [t = 3.32 min*(60 sec/ 1 min) =199 sec]
A/A0 = . 0.551= 55%, (* 100, rounded)
The Arrhenius equation is k = Ae(-Ea/kT), where A is the frequency or pre-exponential factor and e(-Ea/RT) is the fraction of collisions at temperature T that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea).

All of the fringes in Young's double-slit experiment are the same length. The formula yields the fringe width. β = λD/d. Because it depends on L, the spacings between various fringes get smaller as the slit distance gets bigger. Since the space between various fringes is wavelength dependent, increasing the light's wavelength also increases that separation.

Considering the defintion of area of a rectangle and multiplication in scientific notation, you obtain:
the rectangular piece of land with an area of 2.6×10⁵ m² is 2×10³ m long.the width of the rectangular piece is 1.3×10² m.Scientific notationScientific notation is a quick way to represent a number using powers of base 10.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is a whole number, which is called an exponent or an order of magnitude. Represents the number of times the point decimal is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Area of a rectangle
A rectangle is a flat geometric figure with four sides, of which two sides that are opposite parallel to each other have the same length and the remaining two have another length.
The area of a rectangle is calculated from the two different sides (a and b). It is the product of the two contiguous sides of the rectangle:
Area of a rectangle= a×b
where a and b are the measures of the two sides.
Area and length in scientific notationA rectangular piece of land with an area of 260,000 m² is 2,000 m long.
To write the area and length in scientific notation, the following steps are performed:
The decimal point is moved to the left as many spaces until it reaches the right of the first digit. This number will be the value of a in the previous expression. Then: area= 2.60000= 2.6 and length= 2.000= 2.The base 10 is written with the exponent equal to the number of spaces that the decimal point moves. This is a positive number because the decimal point is shifted to the left, and it will have a value of: in the value of area: n=5 and in the value of length: n= 3.So, the rectangular piece of land with an area of 2.6×10⁵ m² is 2×10³ m long.
Width of the rectangular pieceIn this case, you know that a rectangular piece has:
an area of 2.6×10⁵ m².a length of 2×10³ m.Replacing in the definition of a rectangle:
2.6×10⁵ m²= width× 2×10³ m
2.6×10⁵ m²÷ 2×10³ m= width
To divide two numbers in scientific notation, you must divide the numbers that are not powers of 10 (what was previously called the "a" number). To divide the powers of ten, you must subtract the exponents. In this case:
Width= (2.6÷ 2)×10⁵⁻³ m
Width= 1.3×10² m
Finally, the width of the rectangular piece is 1.3×10² m.

What magnitude acceleration does the enterprise need to just barely avoid a collision with the klingon ship? assume the acceleration is constant.
The enterprise must slow down to [tex]-2.5 km/s^{2}[/tex] to avoid a collision.
Describe average velocity.Average velocity is defined as the difference between the change in position or displacement (x) and the time intervals (t) during which the displacement occurs. The average velocity may be positive or negative depending on the displacement's direction. The unit of measure for average velocity in the SI is meters per second (m/s or m[tex]s^{-1}[/tex]).
What are the three equations of kinematics?Only when acceleration is constant and motion is on a straight line can the equations of kinematics be used.
v = u + ats = ut + ½at²v² = u² + 2asLet us assume that,
A = Starship enterprise
B = Klingon ship
Considering that the starship enterprise slows down steadily, the following would be the average velocity:
[tex]v_{a}__{i}[/tex] =( [tex]v_{a}__{i}[/tex] + [tex]v_{a}__{f}[/tex] )/2
where [tex]v_{a}__{f}[/tex] = 0 since it must come to a stop
[tex]v_{a}[/tex] = (50 + 0)/2
[tex]v_{a}[/tex] = 25 km/s
As a result, A must travel 100 km in addition to the distance B travels during that period before coming to a stop:
[tex]d_{A}[/tex] = [tex]d_{B}[/tex] + 100
25t = 20t + 100
5t = 100
So,
[tex]d_{A}[/tex] = 25t
[tex]d_{A}[/tex] = 25(20)
[tex]d_{A}[/tex] = 500 km
and
[tex]d_{A}[/tex] = [tex]v_{a}__{i}[/tex] × t + [tex]\frac{1}{2} a t^2[/tex]
500 = 50(20) + [tex]\frac{1}{2} a(20)^2[/tex]

Balanced forces are those that have opposing directions and equal sizes. One definition of equilibrium is a state of balanced forces.
When the forces are in balance, there is no change in direction.
The sum of balanced forces is always zero. Merging vectors
The momentum or direction of an object cannot be changed by balance forces.
A balanced force keeps an object moving at a steady speed. (Newton’s First Law of Motion)
The Concept of unbalanced forces
Asymmetry of forces
Forces that are not equal in size and differ in direction, always set something moving. (Can alter an object’s direction or speed)
The combined force is equal to the difference between two unbalanced forces acting in opposing directions.
The combined force is equal to the sum of the two unbalanced forces acting in the same direction.
The net force is equal to the resultant when the forces are at right angles.

Draw and add the vectors.
The Pythagorean theorem can be used to find the resultant, which has a magnitude of 15.6 kilometers. The answer is displayed beneath the diagram.
A resultant vector that is directed both north and east can be created by adding together two displacement vectors with magnitude and direction of 11 km north and 11 km east. The hypotenuse of a right triangle is the result of adding the two vectors' head to tail as shown below. The right triangle's sides are 11 km and 11 km long. Scaled vector diagrams are frequently used to represent vector quantities. An arrow drawn to scale and pointing in a particular direction is used in vector diagrams to represent a vector.
