Answer:

1,920 Joules

Explanation:

K.E. = 1/2  mv2

so  K.E. =  1/2 (60)(8x8) = 1,920 Joules

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

Answer:

Option C. Rate of change of velocity

Explanation:

To know the correct answer to the question, it is important we know the definition of power.

Power can be defined as the rate at which work is done. Mathematically, it is expressed as:

Power = work / time

Work and energy has the same unit of measurement i.e joule. Thus, power can also be defined as the rate at which energy is transferred i.e

Power = enery / time

Energy is measured in Joules and time in second. Thus, power can also be defined as amount of joules transfered per second.

Power = Joule / sec

The rate of change of velocity on the other hand is termed acceleration.

Thus, the answer to the question is option C.
