A scientist measures the weights of two different animals. one is 250 grams. the other is 330 grams. in milligrams, what is the
trasher [3.6K]
We know, 1 g = 1000 mg
so, 250 g = 250,000 mg
Also, 330 g = 330,000 mg

So, Difference = 330,000 - 250,000 = 80000

In short, Your Answer would be 80,000

Hope this helps!

Which equation should be used to calculate the speed of a wave?
Yuri [45]

Answer:

Speed (c) = wavelength (λ) × frequency (f)

Explanation:

The wavelength denoted by (λ), is the distance between two successive waves. The wavelength of a wave us calculated by using the formula: (λ) = c/f.

Where; λ= wavelength

c= velocity or speed

f= frequency

Based on this, the speed of a wave can be calculated by making (c) the subject of the formula in λ=c/f.

We have; c = λf

Hence, the speed of a wave equals the wavelength (λ) multiplied by the frequency (f).
