George walks to a friend's house. He walks 750 meters North, then realizes he walked
Sauron [17]

Answer:

I think you are looking for the velocity, so the answer is 38.5 m/s

Explanation:

Velocity is giving by displacement/time. North will be positive and South will be negative, George travels 750 meters then travels -250 meters his displacement is then 750 - 250 or 500 meters. Divide that by 13 seconds to get 38.5 m/s.

The energy gained by electrons as they are accelerated by an electric field is
Ilia_Sergeevich [38]
The energy gained by an electron as it is accelerated by an electric field is equal to the work done by the electric field itself, and this is equal to the product between the charge of the electron and the potential difference across which the electron traveled:
\Delta U = W = e \Delta V (1)
where e is the electron charge, and \Delta V is the potential difference between the initial and the final point of the electron, and this is equal to
\Delta V = Ed (2)
where E is the intensity of the electric field and d is the distance covered by the electron. If we substitute (2) into (1), we find a final expression for the energy gained by the electron
\Delta U = e E d

Suppose that aliens from a planet orbiting Betelgeuse have eyes similar to human eyes, except that the diameter of their pupils
slega [8]

Answer:

Answered

Explanation:

The data given in the problem

Diameter of a human pupil=0.007 m=7 mm

Diameter of alien pupil=0.5=500 mm

Here we have to calculate the minimum distance at which the alien can see Betelgeuse i.e. the focal length (or the working distance). For this calculation we assume the eye to be a spherical lens.

The focal length and diameter of the lens are related by the formula F=\frac{r}{2} Where r is radius of curvature i.e. d/2

Therefore for the alien, focal length=F=\frac{25}{2}=12.5mm=0.0125F=\frac{25}{2}=12.5mm=0.0125

If the spring constant is doubled, what value does the period have for a mass on a spring?
soldi70 [24.7K]

if spring constant is doubled, the mass on spring will be doubled as well. according to this formula, F=ke

k stands for spring constant and e stands for the length extended
