Answer:

he correct answer is Traffic accidents.

Explanation:

Chinese researchers have developed a car that needs the power of brain to operate. It is said to be country's first car that is operated by the mind. The researchers were worried due to the potential road accidents that was caused by the drivers distraction. They believed that concentration is required only while changing the lane or during turns (changing the moving status of car).

A sledge is pulled in a straight line by dogs, as shown. The dogs produce a total horizontal driving force of 600 N. The frictio
kifflom [539]

Answer:

F = 0 N

Explanation:

The direction of air resistance and frictional force will be same and opposite to the direction of the driving fore of dogs. Therefore, the resultant force can be given as follows:

resultant\ Force = F = Driving\ Force\ of\ Dogs - Frictional\ Force - Air\ Resistive\ Forcehere,

driving force of dogs = 600 N

Frictional Force = 150 N

Resultant Force = 450 N

Therefore,

F = 600\ N - 150\ N- 450\ N

<u>F = 0 N</u>

A physicist is calibrating a spectrometer that uses a diffraction grating to separate light in order of increasing wavelength (λ
cluponka [151]

Answer:

Explanation:

Given

N=3680 cm^{-1}

therefore slit spacing d=\frac{1}{N}=\frac{1}{3680}=2.717\times 10^{-4}\ cm

since d\sin \theta =n\lambda

for n=1

d\sin \theta =\lambda

Now,at \theta _1=12.9^{\circ},\Rightarrow \lambda _1=6.0657\times 10^{-7}\ m=606.57\ nm

at \theta _2=14.2^{\circ}\Rightarrow \lambda_2=666.5\ nm

at \theta _3=15^{\circ}\Rightarrow \lambda_3=703.21\ nm
