Answer:
4. It is infrared.
Explanation:
the photosystems on the chlorophyll absorb light at 600-700nm
<span>The correct answer is option C. i.e.Equilateral triangles. All equilateral triangle have equal sides. Due to this these set of shapes will always be similar. Similarity in the sense that only the size of the triangles can change to large or smaller but the shape will be be similar always.</span>
Answer:
t / τ₀ = 2.9
the time constant has to be multiplied by approximately three
Explanation:
The expression for long of a capacitor is
q = q₀ (1- e (-t/τ₀)
Where q is the charge and τ₀ is the time constant. What is found for when the initial capacitor charge at 63.5% (e⁻¹) of the maximum charge
In our case we are asked that the load be 94.5%, this means that
q/q₀ = 94.5%
q/q₀ = 0.945
Let's replace and calculate
q/q₀ = 1 - e (-t/τ₀)
0.945 = 1 - e (-t/τ₀)
(-t /τ₀) = ln (1 -0.945) = ln (0.055)
t / τ₀ = 2.9
the time constant has to be multiplied by approximately three for this charge
The term Point Charge describes a model in which a charge takes up no space and acts uniformly on its surroundings. A Point Charge also creates lines that are uniform in nature and can go both outwards or inwards. When it goes outwards, it shows a positive charge and when it goes inwards then it shows a negative charge.
Answer:
v = 158 m / s
Explanation:
In this kinematic problem they give us the acceleration of the body, the position and speed of the initial moment, let's use the definition of acceleration
a = dv / dt
dv = a dt
We integrate
∫ d v = ∫ (2t + 1) dt
v = 2 (2t²) + 1t
We evaluate between the initial time t = 0 that has speed (vo) 8 m/s and the final time t with speed v
v -8 = 4t2 + t
We already have the velocity formula as a function of time, let's calculate for t = 6 s
v = 8 + 4 6² +6
v = 158 m / s
