Adeep-space probe moves away from earth with a speed of 0.51 c. an antenna on the probe requires 3.9 s (probe time) to rotate through 1.5 rev. how much time is required for 1.5 rev according to an observer on earth? answer in units of s.

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

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
