The sun is shown as a yellow circle. Which of the blue lines best represents the revolution of Earth?

A.
A circle made of a dashed blue line with a smaller yellow circle just inside the blue line is shown. The blue circle represents the revolution of Earth, and the yellow circle represents the sun.
B.
A circle made of a dashed blue line with a smaller yellow circle in the middle of the blue circle is shown. The blue circle represents the revolution of Earth, and the yellow circle represents the sun.
C.
A circle made of a dashed blue line with the blue line passing through a a smaller yellow circle is shown. The blue circle represents the revolution of Earth, and the yellow circle represents the sun.
D.
A circle made of a dashed blue line with a smaller yellow circle just outside the blue line is shown. The blue circle represents the revolution of Earth, and the yellow circle represents the sun. (And how do i add pictures...)

For problems 1-3, consider a simple dc brush motor with a permanent magnet stator. with an an consider a simple dc brush motor with a permanent magnet ae supply voltage of 100 v, the no-load speed of the motor is 1000 rpm. this motor can provide a torque of 1.9 n-m at 800 rpm drawing a current of 2 a current are both zero at no load.) 1. with an armature supply voltage of 100 v, the motor is operated at 900 rpm. what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input? what is the energy efficiency of the motor? with an armature supply voltage of 100 v, the motor is operated at 1100 rpm (where it acts as a generator). what torque input is required? what mechanical power is required what current is generated? what is the electrical power generated? what is the energy efficiency of the motor acting as a generator? 2. with an armature supply voltage raised to 120 v, the motor is operated at 1000 rpm. what is the no-load speed? what is the motor torque? what is the mechanical power delivered by the motor? what is the current draw? what is the electrical power input what is the energy efficiency of the motor? 3.
