<span>It's more accurate than scale diagrams.
You don't need tools (graph paper, protractor etc)
Also, if you are using computers, it easy to programmme.</span><span>

Answer:
Binding Energy = 2.24 eV
Explanation:
First, we need to find the energy of the photon of light:
E = hc/λ
where,
E = Energy of Photon = ?
h = Plank's Constant = 6.626 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of light = 400 nm = 4 x 10⁻⁷ m
Therefore,
E = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(4 x 10⁻⁷ m)
E = (4.97 x 10⁻¹⁹ J)(1 eV/1.6 x 10⁻¹⁹ J)
E = 3.1 eV
Now, from Einstein's Photoelectric Equation:
E = Binding Energy + Kinetic Energy
Binding Energy = E - Kinetic Energy
Binding Energy = 3.1 eV - 0.86 eV
<u>Binding Energy = 2.24 eV</u>
La velocidad del buzo es de 7.04 m/s, 8.84 m/s y 2.27 m/s respectivamente.
<h3 /><h3>Velocidad
</h3>
La velocidad es la relación entre la distancia total recorrida y el tiempo total empleado. Está dado por:
Velocidad = distancia/tiempo
Para 10m de altura:
- Velocidad = 10 m/1.42 s = 7.04 m/s
Para 3m de altura:
- Velocidad = 3 m/0.78 s = 3.84 m/s
Para 1m de altura:
- Velocidad = 1 m/0.44 s = 2.27 m/s
La velocidad del buzo es de 7.04 m/s, 8.84 m/s y 2.27 m/s respectivamente.

I believe the answer is A.
Since the Earth is in the Milky Way and not outside it, we cannot see the exact shape of it. Physicists have been able to track and graph the movements of the planets accurately for thousands of years, but that does not mean we know the shape of the entire solar system.<span />
Answer:
You're strong.
Explanation:
I've been thinking of this for quite a while, and I realized that your body has a certain limit to how much pain it can take. So, punching yourself extremely hard will cause pain, because that's your body's reaction to immense pressure being put on it. But, the fact that you punched yourself so hard that it hurts, shows that you are capable of applying so much pressure; therefore, you are strong.
