.Express 3.0x10-4 -1.7x10-6 with proper significant figure.
Sav [38]
Because of BOMDAS, you do the multiplication first.

(3.0x10) - 4 - (1.7x10) - 6

= 30 - 4 - 17 - 6

= 3

Let’s say a small person with a mass of 50 kg walks up two flights of stairs. A heavy person with a mass of 105 kg walks up the
polet [3.4K]

Answer:

Heavier person

Explanation:

Work = force × distance.  In this case, force = weight and distance = height of the stairs.  For both people, the height of the stairs is the same.  Since the heavier person has more weight, they did more work.

When cs-137 decays, it emits gamma radiation. the energy of one photon is 1.06 × 10-13 j. what is the wavelength of this radiati
Kryger [21]
To find the solution to the problem, we would be using Planck's equation which is E = hv
Where:
E = energy
h = Planck's constant = 6.626 x 10-34 J·s
ν = frequency
Then, you’ll need a second equation which is c = λν
Where:
c = speed of light = 3 x 108 m/sec
λ = wavelength
ν = frequency
Reorder the equation to solve for frequency:ν = c/λ
Next, substitute frequency in the first equation with c/λ to get a formula you can use:
E = hν
E = hc/λ
But we are looking for the wavelength, so rearrange it more, then our final equation would be:
λ = hc / E 
λ = (6.625E-34)(3.0E8 m/s) / (1.06E-13) 
λ = 1.875E-12 m
