The moon is 230,100 miles from planet earth.
<span>A photon is characterized by either a wavelength, denoted by λ or equivalently an energy, denoted by E. There is an inverse relationship between the energy of a photon (E) and the wavelength of the light (λ) given by the equation:
E=hc/λ
E=hc/λ
where h is Planck's constant and c is the speed of light. The value of these and other commonly used constants is given in the constants page.
h = 6.626 × 10 -34 joule·s
c = 2.998 Ă— 108 m/s
By multiplying to get a single expression, hc = 1.99 Ă— 10-25 joules-m
E=hc/λ
(6.626*10^-34 J*s) x (2.998Ă—10^8m/s)/ 1.5*10^-8 m
= 1.32*10^-17 J</span>
Answer:
Shoe size is continuous because it is a gradual change that changes over time, but stops when our feet is at its full length
Q = m.Lf.
Here, m = 18.6 g
Lf = 333 J/g
Substitute their values,
Q = 18.6 × 333 = 6193.8 J
We know, 1 KJ = 1000 J
So, 6193.8 J = 6.193 KJ
In short, Your Answer would be Option D
Hope this helps!
Hello:
First, <u>the normal force</u> in y axis:
∑Fy = 0
∑Fy = N - Fy
∑Fy = N - 20 N * sen 37°
∑Fy = N = 12,87 N
Formula:
R = ma
F - F' = ma
F - (μN) = ma
20 N - (0.2 * 12,87 N) = 3 kg * a
20 N - 2.574 N = 3 kg * a
17,426 N / 3 kg = a
a = 5,8 m/s²
