A decrease in the angle between the wires will increase the horizontal component of tension (the tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides) and an increase in the angle will decrease the horizontal component of tension.
What is tension force?Tension is defined as force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over length of the wire and pulls energy equally on the bodies at the ends.
Every physical object which is in the contact, exerts some force on one another. These contact forces are assigned names based on kind of objects. If one of the forces exerting an object is rope, cable or chain, we can call it tension.
Cables and Ropes can be used for exerting forces since they can efficiently transfer force over a specific distance (e.g. the rope length). Please note that tension is pulling force since ropes cannot push effectively. Pushing with a rope causes the rope to go slack and lose tension that allowed it to pull in the original place. This might seem obvious, but when it is about drawing forces acting on an object, some often draw the force of tension going in the wrong direction. Hence, tension can only pull the object.
In the almost every situation in classical mechanics, you will be presented with massless ropes and cables. When a rope is massless, it transfers force from one end to the other perfectly.

shot from a cannon in 1998, david "cannonball" smith set the distance record for being shot from a cannon (56.64 m). during a launch in the cannon’s barrel, his speed increased from zero to 80 km/h in 0.40 s. while he was being stopped by the catching net, his speed decreased from 80 km/h to zero with an average acceleration of 180 m/s2m/s2. what can you determine about smith’s flight using this information?
From this information, it can be determined that
acceleration of the shot = 56 m/s^2
stoppage time = 0.123s
stoppage path length = 1.37m
CalculationThe average acceleration while being shot by definition
a = [tex]\frac{\frac{80}{3.6} }{0.4}[/tex] = 56 m/s^2
Assuming that there is a constant acceleration we can determine the path covered during his acceleration as
s = 1/2a (0.4s)^2 = 4.5m
then we can find the stoppage time as
t3 = [tex]\frac{\frac{80}{3.6} }{180}[/tex] = 0.123s
Then the stoppage path length is defined as
s3 = [tex]\frac{(80/3.6)^2}{2a}[/tex] = 1.37m
Then the path length of travel with constant velocity is
s2 = 56.64m -s1 - s2 = 50.77m
Then time of flight
t2 = [tex]\frac{s_{2} }{80/3.6}[/tex] = 2.28s
Then we can determine the total time of flight as
t = t1 + t2 + t3 = 2.8s
Thus, we have
ashot = 56m/s^2
tstop = 0.123s
[tex]\delta x[/tex]stop = 1.37m

Given that vector a b = c, and that lal lbl = lcl, how are vectors a and b oriented with respect to each other?
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.
What is a vector?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.

if you are driving 120 km/h along a straight road and you look to the side for 2.2 s , how far do you travel during this inattentive period?
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.
What connection exists between time, distance, and speed?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.

At a certain temperature, the phph of a neutral solution is 7.68. what is the value of kwkwk_w at that temperature?
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)]=10^{-7.68}[/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
Calculating Kw:
Kw = (2.089×10^-8M) *(2.089×10^-8M)
Kw = 4.36×10^-16

the home owner report that sometimes the electric furnace trip the 240-v 60-a circuit breaker connected to it
The homeowner has reported that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it. Upon examination, it is found that the furnace contains three 5000-W heating elements designed to turn on in stages.
SolutionThe power rating of the circuit breaker = volt x current
= 240 x 60
= 14400 W
So, we have 3 units of 5000W each.
Explanation and RecommendationWhen the first unit is turned on, the consumption is 5000W and the circuit breaker does not trip. When two of the 5000W units are turned on, it adds up to a consumption of 10000W.
The circuit breaker is still intact. But when the 3rd 5000W unit is turned on, the consumption reached to 15,000W which is greater than the 14,400W mark, and thus the circuit breaker trips off.
So, switching on all three units at once can cause the circuit breaker to trip off.
So, the recommendation would be that at a particular time maximum of two units can be turned on.
Even such, the two units cannot be turned on in series or they won’t receive 240 V each.
Another recommendation would be to use a circuit breaker of a higher power rating, more than 15,000W so that there will be no tripping.

Write a differential equation for the concentration of the chemical in the pond at time t. hint: the concentration is c = a/v = a(t)/106
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)
