Simple cells have liquid chemicals, making it harder for it to carry. While as dry cells have no liquid chemicals, making it easier to carry.
Answer:
A.model the reflection of a light wave
The Wave Model of Light Toolkit provides teachers with standards-based resources for designing lesson plans and units that pertain to such topics as the light's wavelike behaviors, wave-particle duality, light-wave interference, and light polarization
B. .model the absorption of a light wave
The simplest model is the Drude/Lorentz model, where the light wave makes charged particle oscillate while the particle is also being damped by a force of friction (damping force)
A mirror provides the foremost common model for reflective light wave reflection and generally consists of a glass sheet with a gold coating wherever the many reflections happen. Reflection is increased in metals by suppression of wave propagation on the far side their skin depths
C.model the transmimssion of a light wave
The Wave Model describes how light propagates in the same way as we model ocean waves moving through the water. By thinking of light as an oscillating wave, we can account for properties of light such as its wavelength and frequency. By including wavelength information, the Wave Model can be used to explain colors.
Explanation:
The answer would be A, as B refers to conduction and C and D refer to radiation. Convection is the transfer of different temperature currents, i.e, A
Answer:
![4.01\cdot 10^{-7} m](https://tex.z-dn.net/?f=4.01%5Ccdot%2010%5E%7B-7%7D%20m)
Explanation:
When an electromagnetic wave passes through the interface between two mediums, it undergoes refraction, which means that it bents and its speed and its wavelength change.
In particular, the wavelength of an electromagnetic wave in a certain medium is related to the index of refraction of the medium by:
![\lambda=\frac{\lambda_0}{n}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7B%5Clambda_0%7D%7Bn%7D)
where
is the wavelength in a vacuum (air is a good approximation of vacuum)
n is the refractive index of the medium
In this problem:
is the original wavelength of the wave
n = 1.47 is the index of refraction of corn oil
Therefore, the wavelength of the electromagnetic wave in corn oil is:
![\lambda=\frac{5.89\cdot 10^{-7}}{1.47}=4.01\cdot 10^{-7} m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7B5.89%5Ccdot%2010%5E%7B-7%7D%7D%7B1.47%7D%3D4.01%5Ccdot%2010%5E%7B-7%7D%20m)
The new speed of car is 10.9 m/s

According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.
Mass of the railroad car, m₁ = 7950 kg
Mass of the load, m₂ = 2950 kg
It can be assumed as the speed of the car, u₁ = 15 m/s
Initially, it is at rest, u₂ = 0
Let v is the speed of the car. It can be calculated using the conservation of momentum as :
![m_1u_1 + m_2u_2 = (m_1 + m_2) v](https://tex.z-dn.net/?f=m_1u_1%20%2B%20m_2u_2%20%3D%20%28m_1%20%2B%20m_2%29%20v)
![v =\frac{m_1u_1}{m_1+m_2}](https://tex.z-dn.net/?f=v%20%3D%5Cfrac%7Bm_1u_1%7D%7Bm_1%2Bm_2%7D)
![v = \frac{7950*15}{7950+2950}](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B7950%2A15%7D%7B7950%2B2950%7D)
![v= 10.9 m/s](https://tex.z-dn.net/?f=v%3D%2010.9%20m%2Fs)
Therefore, the new speed of care is 10.9 m/s
