Answer:

the moon is closer to the earth than sun

have a beautiful day

Answer:

3.33 m/s

Explanation:

1/2 = 1/5 + 1/x

1/x = 1/2 - 1/5

1/x = 5/10 - 2/10

1/x = 3/10

x = 10/3

x = 3.33 m/s

→ The charge in electron charge Q(e) is equal to the charge in coulombs Q(C) times 6.24150975⋅1018:

1C = 6.24150975⋅10¹⁸e

Q(e) = Q(C) × 6.24150975 × 10¹⁸

Q(e) = 96,500 × 6.24150975 × 10¹⁸

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.

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.

a = 5m/s^2

Explanation:

Vi=0 m/s

ΔY=10m

Δt=2s

find acceleration

With the givens and the acceleration being the only one missing, we can safely use the Δy = Vi Δt + 1/2 a (Δt)^2 formula

Plug it in and we get:

10 = 0 x 2 + 1/2 a (2)^2

10 = a2

10/2 = a 2/2

a = 5 m/s^2

Explanation:

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]

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.

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

Hi there!

Because of Newton's Third Law, the force exerted by the sprinter on the track is equal and opposite to the force exerted by the track on the sprinter.

We can begin by calculating the sprinter's acceleration. Use the equation:

vf² = vi² + 2ad

Rearrange for acceleration:

(vf² - vi²)/2d = a

Plug in values:

(8² - 2²)/2(2.5) = 60/5 = 12 m/s²

Calculate the force:

∑F = ma

∑F = 60 × 12 = 720 N. This is the amount of force exerted by the track on the sprinter in causing him to accelerate forward.

Thus, the backward force exerted by the sprinter on the track is the opposite, or -720 N.
