Vector a b = c, and that |al |b| = |cl, vectors a and b oriented with respect to each other because they are perpendicular to each other.

A vector is an object that has both magnitude and a direction. Geometrically, we can picture vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of vector is from its tail to its head.

Two vectors are the same if they have same magnitude and direction. This means that if we take a vector and translate it to a new position (without rotating it), then vector we obtain at the end of this process is the same vector we had in beginning.

Two examples of vectors are those that represent the force and velocity. Both the force and velocity are in a particular direction. The magnitude of vector would indicate the strength of the force or the speed associated with the velocity.

We denote vectors using the boldface as in a or b. Especially when writing by hand where one cannot easily write in boldface, people will sometimes denote vectors using the arrows , or they use the other markings. We won't need to use the arrows here. We denote magnitude of the vector a by |a|. When we want to refer to a number and stress that it is not a vector, we can call number a scalar. We will denote scalars with the italics, as in a or b.

Kw = 4.36×10^-16 is the value of kw at temperature when the ph of a neutral solution is 7.68.

The formula for Kw is:

Kw= [H]*[OH]

where [H] and [OH] are concentrations

We are given the pH so we can calculate the [H] concentration from the formula:

pH=-log[H]

[tex]P_{H} =-log_{10} [H^{+} (aq)][/tex]

[tex]-P_{H} =log_{10} [H^{+} (aq)][/tex]

[tex][H^{+} (aq)]=10^{-P_{H} }[/tex]

[tex][H^{+}(aq) ]=[/tex]2.089×[tex]10^{-8}[/tex]mol [tex]dm^{-3}[/tex]

In neutral solution, [H] = [OH],

therefore: [OH]=2.089×10^-8M

The moon appears 1.1153 during perigee than at apogee.

Perigee is the point at which the moon is nearest to the Earth each month.

The points of apogee and perigee varies throughout the year.

Apogee is the point at which the moon is farthest to the Earth each month.

from the data given,

perigee= 364000km

Apogee= 407000km

diameter= 3480km

p/a = 406,000/364,000

= 1.1153.

Thus, the moon appears 1.1153 during perigee than at apogee.

During this inattentive period, the distance traveled is 73.33 when the speed is 120 km/h and the time taken is 2.2 s.

Every moving object travels a particular distance over time. These two factors enable us to determine the speed. The frequency of displacement is the sole determinant of speed. The complete mobility of an object, regardless of direction, will be its distance. No matter where an object originates or finishes, distance measures how much ground it has travelled. A process, an action, or a condition's duration is the amount of time that can be measured or quantified. Speed is the rate at which an object travels along a path over time, whereas velocity is the speed and direction of an item's motion. In another sense, velocity is a vector, whereas speed is a scalar value. There is a formula that connects these three things. Speed can be thought of as a gauge for a body's rate of motion. The distance covered in a single unit of time is how it is defined.

Speed = Distance/ Time

We are given Average speed, = 120 km/h=(120 * 1000)/3600=33.33 m/s

Time, t=2.2s

Now speed =  Distance/ Time

⇒ Distance = speed * time=33.33*2.2=73.33

Thus distance traveled is 73.33 m

Finding the initial and final values for the quantity that the capacitor or inductor opposes changing—i.e., the quantity that the reactive component is seeking to maintain constant—is the first stage.

This amount is voltage for capacitors and current for inductors. This amount is to be used as the "beginning" value because when the switch in a circuit is closed (or opened), the reactive component will try to keep that quantity at the same level as it was before the switch transition. This quantity's ultimate value is whatever it will be after an infinitely long period of time.

The amount of charge that is held in a specific field is determined by the charge density. It is absolutely possible to calculate charge density of an object in terms of length, area, or volume.

If q is taken as the charge and l is the distance that it travels, then q/l is the formula for the linear charge density, and the S.I. Coulombs per meter (cm1) is the unit used to measure linear charge density.

The differential equation for the concentration of the chemical is given by dc/dt = (3/10⁶)(1 - 100c)

Suppose that a(t) is the amount of chemical in the pond at time t.

So, a'(t) = rate of chemical inflow - the rate of chemical outflow.

So, da/dt = (0.01)300 - (a/10⁶)300

So, da/dt = 3 - 3a/10⁴

Now,

Since, c = a/v

Then, c' = a'/v

So, c' = (3 - 3a/10⁴)/10⁶

Or, c' = 3 (1 - a/10⁴)/10⁶

So, dc/dt = 3/10⁶ (1 - cv/10⁴)

So, dc/dt = (3/10⁶) (1 - 100c)
