Finding the common slope of the placement function for the term you're interested by will let you decide the common pace.

average pace and average pace are the same if the arrow constantly actions at a regular tremendous or bad speed. we will first pick out the places of high-quality and negative velocities.
Find the velocity equation first. It is y(derivatives: )'s

Next, find the positive and negative values of this:

If the concentration of mercury in a water supply changes from 65 ppm to 7 ppm in a ten-year period, what is the percentage change of the mercury concentration?
The percentage change of the mercury concentration is 89.2 %
We know that,
Percentage change = [ ( Final value - Initial value ) / Initial value ] * 100
Given that,
Initial value = 65 ppm
Final value = 7 ppm
Time = 10 years
Time is not necessary in a percentage calculation because no matter how it took for something to change only the changed quantity matters.
Percentage change = [ ( 7 - 65 ) / 65 ] * 100
= 0.8923 * 100
Percentage change = 89.23 %
In a percentage change initial value is absolute as it cannot be changed.
Therefore, the percentage change of the mercury concentration in a ten year period is 89.2 %

The resolution of radio telescopes suffers greatly from the large wavelengths of the light they are observing. What can be done to a radio telescope to improve its angular resolution?.
The resolution of radio telescopes suffers greatly from the large wavelengths of the light they are observing. To improve the angular resolution, it can be done to a radio telescope by making its dish bigger.
If the diameter of the objective is large, the value of Δθ will be small. This points out that the telescope will be having resolving power of better experience if it is large. Because for this reason in order to get a better resolution, a large diameter objective type should be occupied by a particular telescope.
The resolution of the telescope is unable to get better because to attempt better resolution, we need a telescope with a high-quality lens or mirror as well as the presence of a large aperture.
In general, resolving power is inversely proportional to the diameter of the particularly given object. So when the larger the diameter and the smaller the angle, then we get an advanced result of better angular resolution, and also the telescope having a large diameter contained mirror would be showing a better view of resolving power.

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

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.

Total vertical velocity = 6510 + 1204.9 = 7714.9 m / sTotal Horizontal velocity = 1204.9 m / sThe resultant velocity makes a right angled triangle with the magnitude of total vertical and horizontal velocity.Since it is a right angled triangle,

In comparison, a traveler in a jet aircraft traveling at 500 mph would cross the continental United States once in 4 hours.The speed of light in a vacuum, denoted c, is a universal physical constant that is important in many fields of physics. The speed of light c equals 299,792,458 meters per second.The speed of light is shared by all forms of electromagnetic radiation, including visible light. Light and other electromagnetic waves appear to propagate instantly for many practical purposes, but their finite speed has noticeable effects over long distances and with very sensitive measurements. Starlight seen from Earth long ago left the stars, allowing humans to study the history of the universe by viewing distant objects.
