Answer:
0.888 ohm
Explanation:
We have given that the battery has an emf of 12 volt that E =12 volt
Terminal voltage V =18.4 volt
Current through the battery is =7.20 A
We have top find the internal resistance of the battery
Now according to Kirchhoff's law V=E+IR
So
So the value of internal resistance of battery is 0.888 ohm
The correct answer is:
<span>A. orbiting closer to the earths surface.
In fact, the gravitational force exerted by the Earth on the satellite is
</span>
<span>where
G is the gravitational constant
M is the Earth mass
m is the satellite mass
r is the distance of the satellite from the Earth's surface
We can see that, if the satellite orbits closer to the Earth's surface, its distance r from the centre of the planet decreases. But when r decreases, F (the gravitational force) increases, so A is the correct answer.</span>
