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

The correct option is 20000 kg m /s.
What is Momentum ?
Momentum is a concept in physics that describes an object's tendency to continue moving in its current direction at a constant speed. It is a vector quantity, meaning it has both magnitude and direction. The momentum of an object is defined as the product of its mass and velocity, and is represented by the equation: p = mv, where p is momentum, m is mass, and v is velocity.
In simple terms, momentum can be thought of as the "motion" of an object, and the larger the mass and velocity of an object, the greater its momentum. Momentum is a conserved quantity, which means that the total momentum of a system remains constant unless acted upon by an external force.
Given , Mass = 1000kg
Speed = 20 m/s
momentum = mv = 20000 kg m /s

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
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]

As the signal turns green, automobile A accelerates at a constant rate of 2 m/s2. Two seconds later, automobile B starts and accelerates at a constant rate of 3.6 m/s2. Determine (a) when B will overtake A, (b) the speed of each automobile at that time, and c) the location where B overtakes A relative to the traffic signal.
Answer:
a) 45 s , b) vₐ = 90 m / s, v_b = 162 m / s, c) x_b = 3.328 10⁴ m
Explanation:
We can solve this exercise using the kinematic relations
Vehicle A
xₐ = v₀ₐ t + ½ aₐ t²
vehicle B
starts two seconds later
x_b = v_{ob} (t-2) + ½ a_b (t-2) ²
as cars start from rest their initial velocities are zero
at the point where they meet, the position must be the same for both vehicles
xa = 0 + ½ aₐ t²
xb = 0 + ½ a_b (t-2) ²
½ aₐ t² = ½ a_b (t-2) ²
[tex]\sqrt{ \frac{a_a}{a_b} }[/tex] t = (t-2)
t (1 - \sqrt{ \frac{a_a}{a_b} }) = 2
t (1 - ⅔, ) = 2
t = 2 / 0.4444
t = 45 s
b)
the speed of each car
vₐ = voa + aa t
vₐ = 0 + 2 45
vₐ = 90 m / s
v_b = 3.6 45
v_b = 162 m / s
c) xb = 0 + ½ ab (t-2) ²
x_b = ½ 3.6 (45-2) ²
x_b = 3.328 10⁴ m

Explain the law of inertia in your own words.
A
An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.
Explanation:
Answer:
Law of inertia is Newton's first law of motion..
Explanation:
It means that a body will tend to be in it's motion or tend to move in a straight line unless any external force is acted upon it..
Eg: while you are travelling in bus.. If breaks are suddenly applied your body falls forward because you were in motion with bus but it tries to be in motion when breaks are applied...

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.
