Answer:
Height of coffee mug = 5 cm
Explanation:
Changing all the data given in to unit cm
50 mm = 5 cm
20 cm = 20 cm
8 m = 800 cm
0.1 km = 100 m = 10000 cm
Since we need to find the height of coffee mug, it's height will not be more than 10 cm.
So 5 cm is the correct choice.
Answer:
false 20 n x 0.32 m = 6.4 J
Answer:
Color
Explanation:
Thus, for stars, considering them as “black bodies”, we can get an approximate figure for their temperature by measuring their dominant frequency (color). Technically scientists measure the brightness of the blue light and that of red light from the star, and from this they can calculate the temperature of the star.
Acceleration is the rate of change of velocity per unit of time.
