3 0
The formula for orbital speed v is    v=(G*Me/r)^1/2
Wher G= 6.67E-11,    Me= 6E24,    r= Re+h= 6.4E6+740000
putting values in the formula we get

v= 7486.7 m/s     or  v= 7.4867 km/s

In a certain region of space, a uniform electric field is in the x direction. A particle with negative charge is carried from x=20.0 cm to x=60.0cm.

<h3>Where is the electric potential, when the particle moved?</h3>

The charge field system's electric potential energy rose. The particle experiences an electric force that is directed against the x-axis. It is pushed uphill by an outside force, which raises the potential energy.

When a charge to be moved against an applied electric field, electric potential energy is needed. A charge must be moved through a stronger electric field with more energy than it would require to carry it via a weaker electric field.

In a certain region of space, a uniform electric field is in the x direction. A particle with negative charge is carried from x=20.0 cm to x=60.0cm.

The electric potential energy of the charge field system:

  • (a) increase
  • (b) remain constant
  • (c) decrease
  • (d) change unpredictably

The correct option is a).

An object has a mass of 120 kg on the moon. What is the force of gravity acting on the object on the moon? A. 12.24 N B. 196 N C
Lady_Fox [76]
Correct answer: B
The force of gravity acting on the object on the moon can be found by multiplying its mass by the acceleration due to gravity on the moon. The acceleration due to gravity on the moon is a constant and is approximately 1.63m/s².
120kg×1.63m/s²=195.6kg.m/s²
kg.m/s²=N
<span>The force of gravity acting on the object on the moon would be of approximately 196N.</span>
