Blue bumper car, traveling east with a force of 100 N, runs into a yellow bumper car traveling west with a force of 300 N. Because the net force will be -200 N. one of the cars will be pushed backward. Which one?
Answer:
the blue bumper car
Explanation:
because the yellow bumper car is coming in with much more force
and according to Newton, actions and reactions are equal and opposite, so the yellow bumper car will five out 300N while the blue car will give out only 100N
then it almost because a fight between 300N vs 100N
and obviously, the 300N will win and the 100N will be pushed back

Henry ran a 100 m race. Use the graph to answer the following:
a. How long did it take for Henry to run 100 m?
b. What is Henry's average speed over the race?
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
Average speed = (100-0)/(20-0)Average speed = 100/20Average speed = 5m/s.Therefore, Henry's average speed over the race is; 5m/s.

What role does a volcano play in our planets dynamic internal activity
Answer:
Volcanic activity acts as a window to a planet's interior. The type of volcanism and the composition of the lava give scientists a peak underneath the crust.

Information travels at 120 metres per second in neurones. Calculate the time it would take for the information to travel 2.3 m along a neurone. Give your answer in milliseconds.
Answer:
5 remainder 5
Explanation:
divide 120 by 2.3
To calculate the time it would take for information to travel a certain distance along a neuron, you can use the formula: Time = Distance / Speed.
Given that the information travels at 120 meters per second and the distance is 2.3 meters:
Time = 2.3 m / 120 m/s
Time ≈ 0.019167 seconds
To convert seconds to milliseconds, multiply by 1000:
Time in milliseconds ≈ 0.019167 s * 1000 ms/s ≈ 19.167 ms
So, it would take approximately 19.167 milliseconds for the information to travel 2.3 meters along a neuron.

an experimental plane, currently overhead, is flying at 120 mph at an altitude of 32 thousand feet. how fast is the plane’s distance from you increasing at the moment when the plane is flying over a point on the ground 24 thousand feet from you?
This question involves the concepts of Pythagora's Theorem and derivatives.
The plane's distance is increasing at a rate of "105.6 ft/" (OR) "72 mph".
First, we will write an expression for the distance between the person and the plane in terms of time. For that purpose, we will use Pythagora's Theorem. Here, the altitude will act as perpendicular, the horizontal distance on the ground will be the base, and the straight line distance between the plane and the person will be the hypotenuse.
[tex]Hyp^2 = Base^2+Perp^2\\s^2 = (vt)^2+(32000\ ft)^2\\s=\sqrt{(vt)^2+(32000)^2}[/tex]
where,
s = plane's distance from the person
v = horizontal speedof the plane = [tex](120\ mph)(\frac{1.47\ ft/s}{1\ mph})[/tex] = 176 ft/s
t = time
Therefore,
[tex]s=\sqrt{(176t)^2+(32000)^2}[/tex]
Taking the derivative with respect to time:
[tex]\\\\\frac{ds}{dt} = \frac{1}{2}\frac{(2t)(176)^2}{\sqrt{(176t)^2+(32000)^2}}\\\\\frac{ds}{dt} = \frac{61952\ t}{2s}[/tex]
where,
[tex]\frac{ds}{dt}[/tex] = rate at which plane's distance is increasing from the person = ?
s = distance = [tex]\sqrt{(24000\ ft)^2+(32000\ ft)^2} = 40000\ ft[/tex]
t = time = [tex]\frac{horizontal\ distance}{v} = \frac{24000\ ft}{176\ ft/s} = 136.36\ s[/tex]
Substituting these values in the equation, we get:
[tex]\frac{ds}{dt}=\frac{(61952)(136.36)}{(2)(40000)}[/tex]
[tex]\frac{ds}{dt}=105.6\ ft/s = 72\ mph[/tex]

Explanation:
In general, sunlight will heat the upper level of water. As you go deeper into the water, the sunlight cannot reach as easily so the temperature is lower.
There are exceptions considering underwater currents like the Gulf Stream or volcanic vents.
how is the lens able to change its refractive power?
Answer:
The lens can sharpen the curvature of its front and back surfaces, increasing its focusing power.
Explanation:
A lens can change its refractive power through sharpening of the curvature of its front and back surfaces, thereby increasing its focusing power.
What is refractive power of lens?The optical power of a lens is the degree to which the lens is able to converge or diverge light.
The optical power of a lens is measured in Diopters, and obtained by taking the reciprocal of the focal length in meters.

Think about the reasons behind the cost of the Birkin bag and explain why it costs $60,000 in your own words. Do you think that this is a good marketing strategy? Why? Can you think of any other products (clothes / elctronics / anything) that use the same strategy? Does it work?
Answer:
In terms of both price and availability, the Birkin bag is as elusive as it is exclusive. For more than two decades, the bag has been the most sought item in the handbag industry. For such a modest bag, that's a lot of staying power (in looks alone, the design itself takes some 18 hours and is done by a single craftsman).
Of course, it's likely that the bag's rarity is what keeps it at the top of every want list. It is difficult, for example, to stroll into a Hermès store and buy a bag –– even if you could afford to pay the minimum price of $10,000. No, you have to be on an elite list to receive a Birkin.
Explanation:
There are alot more things like the Birkin Bag that use the same marketing skills and it works for alot of companies.

A space ship cruises at a constant velocity of 33,155 km/hr for 22.5 minutes. How far does the ship travel in that
time? State your result in kilometers.
Answer:
12,433 km
Explanation:
I got this by doing 33,155 and dividing it by 60, which is km per minute, then I did 552.583333, which is km per minute and multiplied it by 22.5, which equals 12,433 km
To check this you can do 12,433 times 2, which is 45 minutes and then use 552.583333, which is per minute, and multiplying by 15, which is 15 minutes, then add
(12,433 x 2 = 24,866) add 8288.75 [15 minutes] and that gets you 33,155
