Imagine a hydraulic system with two fluid-filled cylinders, each capped with pistons and connected by a tube called a hydraulic line. On one side, a force of 100N moves the piston in the primary cylinder down 1cm . On the other side, the piston over the dependent cylinder, with 5 times the area of the primary, moves 5cm up. Would it be possible to build a system that acts in this way

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction

I'd go with c) winter because that such a small angle. i think summer is 70-90, and autumn/spring are like 40-70.
