Here’s a good photo to reference when converting in the metric system.
Each time you move down a step you move the decimal to the right, each time you move up a step you move the decimal to the left.
We are going from 1.2 kg or kilograms, which is at the very top left of the ladder. To get to mg or milligrams, we would have to make six jumps, so we’d move the decimal over six times.
1.2 > 12. > 120. > 1200. > 12000. > 120000. > 1200000.
So our final answer would be 1,200,000mg.
The frequency of the other wave is 613 Hz or 607 Hz.
The difference between the frequencies of two waves is called the beat frequency.
Here, one wave has a frequency 610 Hz and the beat frequency is 3 beats per second.
Which has a higher frequency is not mentioned. Therefore, there are two possibilities.
Δf = | 610 - 613 | = 3
or
Δf = | 610 - 607 | = 3
Therefore, the frequency of the other wave is 613 Hz or 607 Hz.

Answer:
Watermelon is going at a speed of 
in downward direction
Explanation:
Given
- Height of the Empire State building = 320 m
- Speed of the superman = 24 m/s
since both the motion of both watermelon and the superman is under gravity. The acceleration of both is g in downwards direction. So the relative acceleration between them is zero and when they meet the relative distance covered by them will be the height of the Empire State building.
so let t be the time when they meet given by
Now let v be the velocity of the the watermelon when they meet given by
Answer:
Answer is 519.3 J
Explanation:
GPE = m x g x h
Object Height is equal to 7.2 x sin42 = 7.2 x 0.669 = 4.817m
GPE = 11 x 9.8 x 4.817 =519.3 J
Most probably m value (11kg) has been used as 7.2 mistakenly.
