In order to find the displacement of something, you can calculate it by subtracting the initial distance from the final distance.
7-5 =2
so the mouse would’ve walked a displacement of 2cm
Temperature is a measurement of the average kinetic energy of an object’s molecules
Answer:
8000m/s
Explanation:
Speed is the measure of ratio of distance to time taken to cover that distance.
So speed of wave is calculated as the product of wavelength and frequency.
As the wavelength is given as 20 m and the frequency is given as 400 Hz, then the speed will be
Speed = wavelength × Frequency = 20 × 400
Speed of wave = 8000 m/s.
So speed of wave is 8000 m/s.
In order to find out what it should be the scientific notation, you've got to get it between 0.1 and 9.9, therefore, you've got to divide it by 10 million
46,500,000 / 10,000,000 = 4.65
This is then in the correct form, and you've then got to find the notation.
To do this, you need to keep dividing 10,000,000 until you get to 10.
10,000,000/10= 1,000,000/ 10= 100,000/ 10= 10,000/10= 1,000/ 10= 100/10= 10
You've divided it by ten six times, therefore, the scientific notation is 10^6.
Therefore, 46,500,000 in scientific notation is 4.65 x 10^6
Hope this helps :)
