Answer:
Newton's Third Law
Explanation:
When one object exerts a force on another object, the second object exerts a force on the first object that is equal in magnitude, but opposite in direction; for every action, there is an equal, but opposite reaction; called the law of action-reaction.

It is D
Explanation: Use of these terms stretches back to World War I. One American field order from September 1918 noted, “The First Army will attack at H-Hour on D-Day with the object of forcing the evacuation of the St. Mihiel salient.” Other nations had their own shorthand. In World War I, the French used the code date “le Jour J,” while the British called their operation start days “Z-Day” and “Zero Hour.”

You and your younger sister (who weighs half as much you do) are at a skating rink. You and your sister's both move backward but your sister accelerates at a greater rate.
What is acceleration?The time rate of change of velocity with time.
As both are holding each other, they will be pushed backwards because the skating they wear makes them to move backwards. The equal and opposite force is applied on each other.
The force F =mass x acceleration.
The lesser mass greater will be the acceleration. Your sister with half weight of yours will accelerate more.
Thus, you and your sister's both move backward but your sister accelerates at a greater rate.

When trying to simplify and find the equivalent resistance you should first simplify resistors in _ before simplifying those in _
The equivalent resistance for the parallel connected resistance will be
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]
What is resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω)
Now if two resistances are connected parallel then the voltage on the resistances will be different and the same current will flow from both resistances.
[tex]V_{eq}=V_1+V_2[/tex]
[tex]I_{eq}R_{eq}=I_1R_1+I_2R_2[/tex]
Since [tex]I_{eq}=I_1=I_2[/tex]
[tex]R_{eq}=R_1+R_2[/tex]
Hence the equivalent resistance for the parallel connected resistance will be

The distance between the two nearest points on a wave where the particles are in phase is 2 m. What is the wavelength of the wave?
A. 1/2 m
B. 1 m
C. 2 m
D. 2 seconds
E. none of these
Answer:
Suppose that the wave equation is:
f(x) = A*cos(k*x)
The wave is in phase for two points x₁ and x₂ if:
f(x₁) = f(x₂)
And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:
wavelength = x₂ - x₁
In this case, we know that the wave is in phase for two points that are 2 m apart.
Then we can use the points:
x₁ and x₂ such that:
x₂ = x₁ + 2m
We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.
Then the wavelength will be:
wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m
Then the wavelength is 2m.

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

A large spool in an electrician's workshop has 65 m of insulation-coated wire coiled around it. When the electrician connects a battery to the ends of the spooled wire, the resulting current is 1.8 A. Some weeks later, after cutting off various lengths of wire for use in repairs, the electrician finds that the spooled wire carries a 2.9-A current when the same battery is connected to it. What is the length of wire remaining on the spool
Answer:
[tex]40.34\ \text{m}[/tex]
Explanation:
[tex]L_1[/tex] = Length of wire = 65 m
[tex]I_1[/tex] = Initial current = 1.8 A
[tex]I_2[/tex] = Final current = 2.9 A
We know
[tex]R\propto \dfrac{1}{I}[/tex]
and
[tex]R\propto L[/tex]
[tex]\dfrac{V}{I}\propto L\\\Rightarrow L\propto \dfrac{1}{I}[/tex]
so
[tex]\dfrac{L_2}{L_1}=\dfrac{I_1}{I_2}\\\Rightarrow L_2=\dfrac{I_1}{I_2}L_1\\\Rightarrow L_2=\dfrac{1.8}{2.9}\times 65\\\Rightarrow L_2=40.34\ \text{m}[/tex]
The length of the wire remaining on the spool is [tex]40.34\ \text{m}[/tex].

Danielle took an iron nail and wrapped thin copper wire around it, then connected the ends of the copper wire to a battery. Which force or forces can Danielle's device produce?
Answer:
yes her device can produce
Explanation:
An electromagnetic force is produced by this setup.
The question suggests the construction of a solenoid with an iron core.I have attached an image. A solenoid has an iron core wrapped around by insulating wires. When the insulating wires are connected to a battery or a voltage source, current flows in the wire and travels through the wrapped region around the iron core. Now, this current produces a magnetic field inside the solenoid, directed along the axis of the solenoid. When the iron core comes under the influence of this magnetic field, it magnetizes and acts as a strong magnet and can produce magnetic force. The force generated through this process is called electromagnetic force.
When the battery is removed, the solenoid returns to its original state, which is it doesn't act as a magnet anymore. By the way, iron retains some magnetization.
