How to convert units of volume in physics?

Units of volume in physics can be converted different ways depending what you have. But the most important thing to remember is that Liters is not the standard unit. the standard unit is meters cubed (m^3). if you think about the volume of a cube is length * width * height. these are length dimensions resulting in meters cubed. You can convert liters to meters cubed by understanding that 1 mililiter = 1 cm^3.

therefore it is possible to convert liters to mililiters. That value is the same as the cm^3 value. from there you can say that (1 meter)^3 = (100 cm)^3. You have to see that the cubed on this is outside the parenthesis. this means that you do not use 100 as the conversion but 100^3 (which is the same as using 1,000,000) so there is 1,000,000 cm^3 per 1 m^3. hope this helps cuz I do not understand the question

Answer choices? if there is any

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
