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.​

Answers

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.

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?

Answers

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 = 100/20

Average speed = 5m/s.

Therefore, Henry's average speed over the race is; 5m/s.

Question 5 (1 point) true or false: Balanced forces acting on an object result in constant velocity True False​

Answers

Answer:

false

Explanation:

By Newton's first law (An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force), neither speed nor direction change. Our force is balanced.

Balance forces could happen when the object is at rest but not all the time. A balance force is when a object is being push in opposite directions, which would cause the object to stay still or move at a constant speed. Which would mean that balance force could take place when a object is moving or when a object is at rest.

how is the lens able to change its refractive power?

Answers

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.

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?

Answers

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]

time? State your result in kilometers.

Answers

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

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?

Answers

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.
