Answer:

3.46 x 10^8 m

Explanation:

Let the distance from the earth be r, total distance from earth to moon be d,

then distance from the moon to the point of equal gravity= d -r.

Mass of the earth, M_E = 598 x 10^22 kg

Mass of the moon, M_m= 7.36 x 10^22 kg

Distance of the mood from the earth, d = 3.85 x 10^8 m

Force of gravity exerted on a mass, m by the earth,

             F_E = G. M_E×m/r^2

Force of gravity exerted on a mass, m by the moon,

              F_m = G×M_m×m/(d-r)^2

These are equal,  So

 G×M_E.m/r^2 =G×M_m.m/(d-r)^2

     [r/(d - r)]^2=  M_E/M_m

    = 598/7.36 = 81.25

      r/(d - r) = √81.25 = 9.014

      9.014×(d - r) = r

    10.014.r = 9.014 x 3.85 x 108

Hence,    r= 9.014 x 3.85 x 108 /10.014

             = 3.46 x 10^8 m

vagabundo [1.1K]

Julia helps the poor performers of her team understand the ways in which they are hurting organizational performance.

The answer is option A.

The senior manager is accountable for planning and directing the paintings of a group of individuals. They monitor their paintings and take corrective moves while essential. Senior managers may manual employees directly or they could direct numerous supervisors, who in turn directly manipulate the employees.

The second level (or third-degree now and again in large agencies) is a senior supervisor. The responsibilities of a senior manager are basically the same as those of a supervisor. They're liable for the administrative and functional path of a collection of personnel.
