Answer:
810 pm
Explanation:
Step 1: Given and required data
- Velocity of the atom (v): 490 m/s
- Mass of a hydrogen atom (m): 1.67 × 10⁻²⁷ kg
- Planck's constant (h): 6.63 × 10⁻³⁴ J.s
Step 2: Calculate the de Broglie wavelength of the hydrogen atom
We will use de Broglie's equation.
λ = h / m × v
λ = 6.63 × 10⁻³⁴ J.s / 1.67 × 10⁻²⁷ kg × 490 m/s = 8.10 × 10⁻¹⁰ m
Step 3: Convert 8.10 × 10⁻¹⁰ m to picometers
We will use the conversion factor 1 m = 10¹² pm.
8.10 × 10⁻¹⁰ m × 10¹² pm/1 m = 810 pm
Explanation:
Modeling crustal deformation is a very important process that helps to study plate interaction that clearly can be used to predict the likelihood of an earthquake.
Earthquake is a sudden displacement or movement with the earth that transmits elastic energy.
- Earthquakes can have shallow or deep focus depending on their location and the terrain.
- Movement on the earth are mostly noticeable along plate margins.
- This results in a world-wide movement of the broken slabs of the earth moving on the weak asthenosphere.
- It is impossible to go deep within the lithosphere to identify unstable earth.
- The uneven distribution of stress is very important in this process.
- As plate moves, the lithosphere deforms creating stresses in some area and relieving other places of stress.
- Continuous collection of stress data using strain mapping gives important parameters that can be modeled.
- Areas with high amount of stress and more movement have the highest tendency of producing earthquakes.
- A computer model is used to carry out this prediction.
- Some other factors contributes to the rapid movement but stress are by far the most important of all.
- By this, we can easily and readily hypothesize the causes of an earthquake and possible measures to mitigate it.

Using charles law
v1/t1=v2/t2
v1=49ml
v2=74
t1=7+273=280k
t2=?
49/280=74/t2
0.175=74/t2 cross multiply
0.175t2=74
t2=74/0.175
t2=422k or 149celcius
Answer:
itd be B because the melting point is 29.76 no matter the size
Explanation:
This is a law because it describes the force but makes not attempt to explain how the force works. A theory is an explanation of a natural phenomenon. Einstein's General Theory of Relativity explains how gravity works by describing gravity as the effect of curvature of four dimensional spacetime.
