Answer:
47.8 °C
Explanation:
Use the heat equation:
q = mCΔT
where q is the heat absorbed/lost,
m is the mass of water,
C is the specific heat capacity,
and ΔT is the change in temperature.
Here, q = 100 kJ, m = 0.5 kg, and C = 4.184 kJ/kg/°C.
100 kJ = (0.5 kg) (4.184 kJ/kg/°C) ΔT
ΔT = 47.8 °C
The wavelength of light is
given as 463 nm or can also be written as 463 x 10^-9 m. [wavelength = ʎ]
We know that the speed of
light is 299 792 458 m / s or approximately 3 x 10^8 m / s. [speed of
light = c]
Given the two values, we can calculate
for the frequence (f) using the formula:
f = c / ʎ
Substituting the given
values:
f = (3 x 10^8 m / s) / 463 x
10^-9 m
f = 6.48 x 10^14 / s = 6.48 x
10^14 s^-1
<span>f = 6.48 x 10^14 Hz</span>
Answer:
I'm pretty sure it should be 4KClO3-->3KClO4+1KCl
Explanation:
Answer:
5.00 × 10^14 Hz
Explanation:
The wavelength of the light in the medium can be calculated by using the formula:
λ = v / f
Where;
λ = wavelength (m)
v = speed of light
f = frequency (Hz)
From the provided information, λ = 600 nm (600 × 10^-9m), v = 3 × 10^8m/s.
λ = v / f
λ = 3 × 10^8/600 × 10^-9
λ = 0.005 × 10^(8+9)
λ = 0.005 × 10^17
λ = 5.00 × 10^14 Hz
The frequency of the light in the medium is 5.00 × 10^14 Hz
