Answer:
11.4 m
Explanation:
We are given that
Total distance traveled by cab,d=214 m
Maximum speed of cab=v=315 m/min=
1 min =60 s
Acceleration of cab=
We have to find the distance traveled by the cab while accelerating to full speed from rest.
Initial speed o f cab=u=0
Substitute the values in the formula
Hence, the cab travel 11.4 m from rest to full speed.
The equation that relates the temperature of an object to the wavelength of its peak radiation is called Wien's law. Wien's law states that: the <span>black body radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature.</span>
Answer:
Wavelength of light is 750 nm.
Explanation:
It is given that,
Frequency of light, 
The relationship between the wavelength and the frequency of light is given by :
Where
c = speed of light
= frequency of light
= wavelength of light
Hence, the correct option is (d) "750 nm".
