The change that will always result in an increase in the gravitational force between two objects is increasing the masses of the objects and decreasing the distance between the objects.

(a) and (b) can increase the gravitational attraction between two objects
IF you pick the increase and decrease just so, but not always.

(d) will always decrease the gravitational force between them.

(c) is the only choice that will always increase the gravitational force between them, no matter how much the increase and the decrease are.

A light wave has a wavelength of 450 nanometers. What is the frequency of this light?

Zolol [24]

Answer:

Frequency, $f=6.67\times 10^{14}\ Hz$

Explanation:

Wavelength of a light wave is 450 nm. It is required to find the frequency of this light wave. The speed of light is given by c. So,

$c=f\lambda$

f is the frequency of this light

$f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{450\times 10^{-9}}\\\\f=6.67\times 10^{14}\ Hz$

So, the frequency of this light is $6.67\times 10^{14}\ Hz$ .

The distance between planets varies as they move in their orbits. The minimum distance from the Earth to Mars is about 0.35 AU.

Alina [70]

Answer:

52,360,000km

Explanation:

To solve this problem you use a conversion factor.

By taking into account that 1UA = 1.496*10^{8}km you obtain:

$0.35UA*\frac{1.496*10^{8}km}{1UA}=52,360,000km$

hence, 0.35UA is about 52,360,000km. This is the least distance between Mars and Earth

Such information is valid when A. it is not biased.
There is no bias in science - the results are either correct or incorrect; personal opinions have nothing to do with that. B is incorrect because the point of experiments is that they can be repeated to achieve the same results. C and D are likewise incorrect as primary sources are important, and you can share the results with others if you want to.
