The rock that is formed by metamorphosing shale is slate.
Answer:
This really depends on the graph but to approach these types of problems you can go about it this way (check explanation)...
Explanation:
(1) What is position?
Where is the object's location at?
If slope is zero, velocity is zero (straight line)
Slope positive, velocity is constant/ positive (linear line positive)
Object is accelerating.. curve upwards.
Steeper the slope, higher the speed
(2) What is velocity?
What are velocity vs. time graphs? - Khan Academy
We already know the formula for finding the energy of a photon with this wavelength as:
<span>E = ħc / λ
</span>The information's that we already know are:
h = Plancks constant
= <span>6.626x10^-34 Js
c = light speed
= </span><span> 2.999x10^8 m/s
</span><span>λ = Wavelength of the light as given in the question
</span> = <span>670.8x10^-9 m
E = amount of energy
Then
E = (</span>6.626x10^-34) * (2.999x10^8)/ (<span>670.8x10^-9)
= </span><span>2.962x10^-19 J</span>
Answer:
θ = θ₀ + ½ w₀ (t -t_1) + α (t -t_1)²
Explanation:
This is an angular kinematic exercise the equation for the angular position
the particle A
θ = θ₀ + ω₀ t + ½ α t²
They say for the particle B
w₀B = ½ w₀
αB = 2 α
In addition, the particle begins at a time t_1 after particle A, in order to use the same timer, we must subtract this time from the initial
t´ = t - t_1
l
et's write the equation of particle B
θ = θ₀ + w₀B t´ + ½ αB t´2
replace
θ = θ₀ + ½ w₀ (t -t_1) + ½ 2α (t -t_1)²
θ = θ₀ + ½ w₀ (t -t_1) + α (t -t_1)²
Answer: Greenhouse gases affect how much of the Sun's energy the Earth loses back to space. Predicting global temperature change is hard, even though the principle sounds easy. In simple terms, energy reaches Earth from the Sun.
