Photon
energy is the energy carried by a single photon with a certain wavelength and
frequency. These terms are related by an equation. <span>
E = hv
<span>where h is the Planck's constant (6.626 x
10-34 J s), v is the frequency which is related to the wavelength by:
λv = c where λ is the wavelength and c is the speed of light (3.00 x
108 m/s)
</span>
Therefore, the energy equation
<span>E = hc / λ
E = (6.626 x 10-34 J s)(3.00 x 10^8 m/s) / 0.0120 m = <span>1.657 x 10^-23 J</span></span></span>
Answer:
Negative
Explanation:
Liquid electrolyte inside battery has work to transfer the charge from one terminal to other terminal..
So here this is carried out by the charge which has more mobility and it must be more in numbers.
So here for more mobility we have to take the negative charge or free electrons present in the electrolyte which carry electricity from one terminal to other terminal with least resistance
so here correct answer would be
b.) Negative
Answer:
3.6×10⁶ m
Explanation:
g = GM / R²
4 m/s² = (6.67×10⁻¹¹ m³/kg/s²) (6×10²⁴ kg) / (6.4×10⁶ m + h)²
(6.4×10⁶ m + h)² = 1.00×10¹⁴ m²
6.4×10⁶ m + h = 1.00×10⁷ m
h = 3.6×10⁶ m
<span><span>A dragster going at 5 m/s north increases
its velocity to 23 m/s north in 4 seconds. What is its acceleration during this
time interval? In order to calculate the acceleration of the boat we first have
to identify the suited formula for acceleration in this scenario. </span>
<span>Hence, a = vf – vi / t. Vi = 5 m/s Vf = 23 m/s T =
4 seconds </span>
<span>Solution: </span>
<span>A = 23 m/s – 5m/s / 4s </span>
A = 4.5m/s^2 </span>
Answer: divergent plate
Explanation: the East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. Here the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, which comprises the Nubian plate.
