Answer:

A.c

Explanation:

The chromosphere is above the photosphere, the visible "surface" of the Sun. It lies below the solar corona, the Sun's upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density.

In basic terms it is the 2nd one out from the core.

What could damage the eardrum and bones of the middle ear?

klio [65]

Answer:

B or D

Explanation:

I wanna say B but I don't really know if it's a trick question

my explanation for D is that anvils are usually 110 decibles and ear drums usually are damaged when exposed to 82dbs or higher at a consistant rate so I'd imagine that'd be the answer I hoped this helped

Asha walks 15 m west, then 20 m north, then 15 m east. Calculate the distance and displacement

Norma-Jean [14]

Answer:

Asha traveled a distance of 50 m

The displacement is 20 m north.

Explanation:

Distance and Displacement

A moving object constantly travels for some distances at defined periods of time. The total moved distance is the sum of each individual distance the object traveled. It can be written as:

dtotal=d1+d2+d3+...+dn

This sum is obtained independently of the direction the object moves.

The displacement only takes into consideration the initial and final positions of the object while moving. The displacement, unlike distance, is a vectorial magnitude and can even have magnitude zero if the object starts and ends the movement at the same point.

Asha walks 15 m west, 20 m north, and 15 m east. The total distance is

dt=15 m + 20 m + 15 m = 50 m

Asha traveled a distance of 50 m

Note the final position is 20 m above the initial position since she goes 15 m west and 15 m east. Thus the displacement is 20 m north.

Two identical closely spaced circular disks form a parallel-plate capacitor. Transferring 2.1×109 electrons from one disk to the

Bad White [126]

Answer:

$d = 0.018 m$

Explanation:

Charge on the plates of the capacitor due to transfer of electrons is given as

$Q = Ne$

here we know that

$N = 2.1 \times 10^9$

so we have

$Q = (2.1 \times 10^9)(1.6 \times 10^{-19})$

$Q = 3.36 \times 10^{-10} C$

now we have electric field between the plates is given as

$E = \frac{Q}{A\epsilon_0}$

here we have

$1.5 \times 10^5 = \frac{3.36 \times 10^{-10}}{A(8.85 \times 10^{-12})}$

$A = 2.53 \times 10^{-4} m^2$

now we have

$A = \frac{\pi d^2}{4}$

$2.53 \times 10^{-4} = \frac{\pi d^2}{4}$

$d = 0.018 m$

A diver initially moving horizontally with speed v dives dives offthe edge of a vertical cliff and lands in the water a distance

Aliun [14]

Answer:

Option C is correct

Explanation:

"The time is determined by the vertical distance. The formula is sqr(2d/a) = t. There still is no acceleration in the horizontal direction."

For the first drive

d = d

t = sqr(2d/a)

r = v

For the Second drive

d = ??

t = sqr(2d/a)

r = 2v

Since the times are same, equate the results.

t = d/v = d1/2v

v*d1 = 2v*d The v's cancel because they are related.

d1 = 2d.

You go twice as far as you did before.

Option C is correct
