In the real world, orbiting objects such as satellites and stations do not need to be constantly accelerating. What is different

about the real world satellites and the theoretical satellites we are discussing here?

What do you mean by theoretical satellites? When you mean real world satellites are you talking about the ones in space because I'm not sure what else you talking about.. I wanna help but could you explain plz??

The net force on the charge at the origin is -1.2×10-8

<u>Explanation:</u>

Solving the problem,

  • Draw the x-axis and the locations of the given three charges.
  • The forces applied on the charge at the origin and there are two of them, and since all the changes are positive, all the forces are repulsive.
  • we have the formula, F = kq1Q/r².
  • F1 = kq1Q/r²1 = (9.0*109Nm²/C²)(2.2*10^-9C)(3.5*10^-9C)/(1.5m)² = 31*10-9N = 3.1*10-8N.  F1 points to the right (+x direction).
  • F2 = kq2Q/r²2 = (9.0*109Nm²/C²)(5.4*10^-9C)(3.5*10^-9C)/(2.0m)² = 43*10^-9N = 4.3*10^-8N.
  • F2 points to the left (-x direction).
  • To find the net force we have to subtract the force F1 and force F2 .
  • The net force is F(origin) = F1 - F2 = -1.2×10-8N.

An object is at rest. There are several forces acting on the object, but the net force is zero. If all the
pantera1 [17]
It would not. Imagine four forces equal in magnitude but opposite in direction (e.g. north, east, south, and west). If these forces were to double in magnitude they would still have the same magnitude, meaning the net force is still equal to zero.

Could someone explain to me how to got the answer B, thank you very much​
Mnenie [13.5K]

Answer:

since -6 lasted for 5 seconds, multiplying both would result in -30

3 lasted for 10 seconds, so multiplying both would give +30

average = ( 30 + (-30) ) / 2

30 -30 is already equal to zero, so the answer should be 0
