Answer:
18,000 j
Explanation:
the lightbulb dissipates 5W of power
P = ΔE / Δt
rearrange to solve for energy
ΔE = PΔt
P = 5W
t = 1 hour = 60 minutes = 3600 seconds
ΔE = 5 * 3600
ΔE = 18000 J
Answer: DNA polymerase and DNA ligase also are important in DNA replication. In addition to maintaining the integrity of DNA sequences by DNA repair, an accurate duplication of DNA is a prerequisite for all cell divisions.
It's a bit of a trick question, had the same one on my homework. You're given an electric field strength (1*10^5 N/C for mine), a drag force (7.25*10^-11 N) and the critical info is that it's moving with constant velocity(the particle is in equilibrium/not accelerating).
<span>All you need is F=(K*Q1*Q2)/r^2 </span>
<span>Just set F=the drag force and the electric field strength is (K*Q2)/r^2, plugging those values in gives you </span>
<span>(7.25*10^-11 N) = (1*10^5 N/C)*Q1 ---> Q1 = 7.25*10^-16 C </span>
I’m slightly confused about the wording of the question but if both the same y-intercept that means both company’s have the same flat rate charge for artwork.
Answer:
The frequency of the green light is 
Explanation:
The visible region is part of the electromagnetic spectrum, any radiation of that electromagnetic spectrum has a speed of 
in the vacuum.
Green light is part of the visible region. Therefore, the frequency can be determined by the following equation:
(1)
Where c is the speed of light, 
is the wavelength and 
is the frequency.
Notice that since it is electromagnetic radiation, equation 1 can be used. Remember that light propagates in the form of an electromagnetic wave (that is a magnetic field perpendicular to an electric field).
Then, can be isolated from equation 1
(2)
Notice that it is necessary to express the wavelength in units of meters.
⇒ 
Hence, the frequency of the green light is
