Which set of terms is in the proper order, from left to right, for labeling the

How much work w is done by the electrostatic force on the moving point charge?

V125BC [204]

As we know that electrostatic force is a conservative force

so we can say by the condition of conservative force

$F_c = -\frac{dU}{dr}$

here we can rearrange the above equation as

$dU = - F_c.dr$

now integrate both sides

$\int dU = - \int F_c . dr$

Now we know by the definition of work done by a force is given by

$W = \int F.dr$

now work done by conservative force is given as

$W_c = \int F_c . dr$

Now from above work done by electric field to move charge from one point to other is given as

$W_{EF} = \int F_{e}.dr = - \int dU$

so here work done is given as

$W_{EF} = U_i - U_f$

so change in potential energy is given by work done

From hottest to coolest, the order of the spectral types of stars is _________. From hottest to coolest, the order of the spectr

Dimas [21]

Answer:

OBAFGKM

Explanation:

Most stars are classified using the Morgan-Keenan system, which consists of assigning a letter to the star depending on its temperature. The hottest stars are type O, and the coldest stars are type M. As for their color, the coldest stars tend to have red color and the hottest have blue colors.

Within each of these divisions (OBAFGKM), there is another division that are the numbers from 0 to 9: 0 is hotter and 9 colder, to get a better classification of a star.

The order of the letters of the Morgan – Keenan system classification, according to the temperatures is as follows:

O: temperatures greater than 33,000K

B: temperatures between 10,000K and 33,000K

A: temperatures between 7,500K and 10,000K

F: temperatures between 6000K and 7.500K

G: temperatures between 5,200K and 6,000K

K: temperatures between 3,700k and 5,200K

M: temperatures below 3,700 K

An airplane traveling at 60 m/s comes to a stop in 10 seconds. Calculate the airplane’s acceleration. Show the appropriate formu

valkas [14]

Answer:

-6m/s^2

Explanation:

Acceleration is the quantity that increase or decrease the velocity per time unit, that means, we can obtain that quantity by dividing change in velocity between time, in this case a=(Vfinal-Vinitial)/t, replacing a=(0m/s-60m/s)/10s , so a=-6m/s^2.
