Which of the following is not the same as 0.00684 kg?
olchik [2.2K]

kg and all the given units are units used to measure mass.

kg is the standard unit to measure mass

lets find the value of 0.00684 kg in all the given units

a. dkg

1 kg is equivalent to 100 decagram (dkg)

therefore 0.00684 kg is = 100 dkg/kg x 0.00684 kg = 0.684 dkg

this is not the given value therefore this choice is incorrect

b. 1 kg is equivalent to 1000 g

therefore 0.00684 kg = 1000 g/kg x 0.00684 kg = 6.84 g

this is the given value so this is correct

c. 1 kg is equivalent to 100 000 centigrams (cg)

therefore 0.00684 kg = 100 000 cg/kg x 0.00684 kg = 684 cg

this is the given value so this is also correct

d) 1 kg is equivalent to 1 000 000 mg

therefore 0.00684 kg = 1 000 000 mg/kg x 0.00684 kg = 6 840 mg

this too is correct

the incorrect answer is A. 0.0684 dkg

If an electromagnetic wave has a frequency of 4.5 x 10^18 Hz, what is its wavelength? The speed of light is 3 x 108 m/s.
Mekhanik [1.2K]

Answer:

Wavelength, λ  = 6.7 x 10^-11 m

Explanation:

Frequency and wavelength are inversely proportional to each other.

In this problem;

f =  4.5 x 10^18 Hz

wavelength, λ = ?

Speed of light, c = 3 x 108 m/s.

These variables are related by the following equation;

c = λ * f

Making λ subject of focus, we have;

λ = c / f

λ = 3 x 10^8 / 4.5 x 10^18

λ  = 0.67 x 10^-10

λ  = 6.7 x 10^-11 m
