Hi there!

1. Weather is the condition in a day describing humidity, temperature, and rain or sun conditions. It also includes different features, including hail, snow, and storms.

2. Our atmosphere provides the air we need to breath. It also protects us from harmful UV rays from the sun, and it traps heat to ensure that the planet doesn't freeze.

3. We might have storms such as thunderstorms, or gusts of warm air coming our way. This is caused by the warm front.

4. Yes, it is possible that humans and dinosaurs drank the same water. Because of the water cycle and that water on earth never leaves the atmosphere since it is always cycled or recycled, it is possible that the same water, just in different states, have been in the mouth of a dinosuar.

Hope this helps!

Answer:

The radius of the gold nucleus is 7.1x10⁻¹⁵m

Explanation:

The nearest distance is:

r=\frac{kze^{2} }{mpV^{2} } (eq. 1)

Where

z = atomic number of gold = 79

e = electron charge = 1.6x10⁻¹⁹C

k = electrostatic constant = 9x10⁹Nm²C²

energy of the particle = 32 MeV = 5.12x10⁻¹²J

At the potential energy is zero, all the energy will be kinetic energy:

E_{k} =\frac{1}{2} m V^{2}

Where

m = 4 mp = mass of proton

5.12x10^{-12} =\frac{1}{2} *4*m_{p}* V^{2} \\m_{p}* V^{2} = 2.56x10^{-12}

Replacing in equation 1

r=\frac{9x10^{9}*79*(1.6x10^{-19})^{2}   }{2.56x10^{-12} } =7.1x10^{-15} m

why does diving 30m below sea level affect our bodies more than being in a building 30m above sea level
Genrish500 [490]
Imagine you are in a swimming pool 30m deep. Assuming you know that water is denser than air, you would know that the 30m of water above you will carry more weight, and press down on your body. Say you were in a swimming pool 60m deep, you would be sandwiched between 30m of water pressing down on you, and the upthrust created by the 30m of water below you.

In a building 30m up, the pressure will be regulated, as you are in a building. The floor will be strong enough to support the weight of the body, and the body will not recoil into itself.
