Answer:

It would remain the same on Earth (5-kg) but on the moon, it would be 1-kg

Explanation:

To discover the weight on the moon, we partition the weight on earth by the world's power of gravity, which is 9.81m/s2. This ascertains the mass of the article. When we have the article's mass, we can discover the weight by increasing it by the gravitational power, which it is dependent upon.

Bogdan [553]

Answer:

$4.58\times 10^{14}Hz$ $5.825\times 10^{14}Hz$ $6.31\times 10^{14}Hz$

Explanation:

We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as $v=\nu \lambda$ where v is speed of light $\nu$ is frequency of light $\lambda$ is wavelength of light

In first case we have given λ=655 nm

so using formula $v=\nu \lambda$

$3\times 10^8=655\times 10^{-9}\times \nu$

$\nu =4.58\times 10^{14}$ Hz

In second case we have wavelength 515 nm so by using above formula

$3\times 10^8=515\times 10^{-9}\times \nu$

$\nu =5.825\times 10^{14}\ Hz$

In third case we have wavelength 475 nm

so $3\times 10^8=475\times 10^{-9}\times \nu$

$\nu =6.31\times 10^{14}Hz$

suppose larry stands with more weight on one scale than the other if one scale reads 400 N. what does the other read?

Evgen [1.6K]

The other scale will either have a higher or lower number because 400 could be the bigger number or the smaller number but we don't know that so you cant exactly answer it.<span />
