It would be on the top of the HR diagram, specifically, the top right.
Answer: When you name an element, it's usually because the element is newly discovered. So by naming an element you are creating something that will last throughout history.
Explanation:
K.E = 1/2 mv²
100 = 1/2 (2 )(v)²
100 = both 2 cancel (v)²
Taking Square root on b/s
√100 = √v²
10 = v
...because velocity is a vector quantity, which means that it includes both the magnitude and the direction of motion.
The speedometer only measures the speed of the car and not its velocity. Speed is a scalar quantity, which means that it only indicates magnitude and not direction of the motion. Thus, the speedometer only shows the distance covered by the car with time (speed), but it does not indicate if the car is moving forward, backward, left or right.
Speed = wavelength * Frequency
s = 247 /s * 1.4 m
s = 345.8 m/s
In short, Your Answer would be 345.8 m/s
Hope this helps!
