Answer:
percipitation, i took this tet and got it correct.
Explanation:
Answer:
The particle model, because the metal is only absorbing radiation
of specific frequencies
Explanation:
The heating of a metal is an example of blackbody radiation. Blackbody radiation refers to the spectrum of light emitted by any heated object; common examples include the heating element of a toaster and the filament of a light bulb. The spectral intensity of blackbody radiation peaks at a frequency that increases with the temperature of the emitting body(Encyclopedia Britianica).
Max Plank proffered explanation to black body radiation by assuming that the oscillators in the heated body emit or absorb energy in discrete frequencies given by E=hf. Hence the energy was directly proportional to the frequency of the oscillator.
Answer:
a. Yes, because the acceleration of the crate is 2.0 m/s².
Explanation:
Given
--- f
--- m
--- t
--- v
Required
Does the system support
Yes, it does and this is shown below
The crate is initially at rest; so:
Using the first equation of motion
Substitute values for v, u and t
Make a the subject
Using
Substitute values for F and m
Divide both sides by 3
In both cases:
<em>Hence, option (a) is correct.</em>
Your would have to subtract because when it how long does it takes it to reach
