h = 4004.349 km

Explanation:

Given,

The mass of the Earth, M = 6 x 10²⁷ km

The radius of the Earth, R = 6.4 x 10³ km

At what height the acceleration of the meteor is, h = 4 m/s²

The acceleration due to gravity at the surface of the Earth is given by the formula,

g = GM/r²

At height 'h' acceleration is given by the formula,

$g_{h}$ = GM/ $R_{h}^{2}$

Where,

$R_{h}^{2}$ = R + h

$R_{h}^{2}$ = GM/ $g_{h}$

$R_{h}^{2}$ = 6.673 x 10⁻¹¹ X 6 x 10²⁴ / 4

= 1.00095 x 10¹⁴

$R_{h}$ = 10004748.87 m

= 10004.749 km

From above,

$R_{h}$ = R + h

h = $R_{h}$ - R

= 10004.749 km - 6400 km

= 4004.349 km

Hence, the hieght of the meteor where its acceleration due to gravity is 4 m/s² is, h = 4004.349 km

Answer from: Quest

what question you dont ask a question

explanation:

Answer from: Quest

distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

slope of a graph = change in value of y -axis / change in values of x -axis

comparing both the equations

change in value of y -axis = change in position

change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
