The gravitational force produced between any two objects kept 2.5×10^4 km apart is 580 N . At what distance should they be kept
DochEvi [55]

Answer:

Formula for gravitational force    F = G M1 * M2 / R^2  where G is the gravitational constant

F2 / F1 = (R1 / R2)^2 = 1/2         where F2 is the required force

R2 = (2)^1/2  R1     distance for R2 to be 1/2 force at R1

Since force is proportional to the square of the distance of separation, increasing the distance of separation by 2^2 will halve the force

Before using the Gizmo, consider an arithmetic sequence with a first term (a1) of 4 and a common difference (d) of 3.
mote1985 [20]

Answer:

<h2>4, 7, 10, 13 and 16</h2>

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as Tn = a+(n-1)d.

a is the first term of the sequence

d is the common difference

n is the number of terms

Given the first term a = 4 and common difference d = 3, we can calculate the first five terms of the sequence using the formula.

If n = 2

T_2 = 4+(2-1)*3\\T_2 = 4+(1)*3\\T_2 = 4+3\\T_2 = 7\\\\when \ n = 3;\\T_3 = 4+(3-1)*3\\T_3 = 4+(2)*3\\T_3 = 4+6\\T_3 = 10\\\\when\ n = 4\\T_4 = 4+(4-1)*3\\T_4 = 4+(3)*3\\T_4 = 4+9\\T_4 = 13\\\\when\ n = 5\\T_5 = 4+(5-1)*3\\T_5 = 4+(4)*3\\T_5 = 4+12\\T_5 = 16\\

The first five terms of the sequence from lowest to highest are 4, 7, 10, 13 and 16
