Which of these discoveries is generally attributed to newtonA).The force of gravity acts between any two objects
B). The earth is round
C). Planets Move In circles
D). The orbit of mars is an ellipse

Explanation :

The momentum of an object is defined as the product of its mass and the velocity with which it is moving. It is denoted as p.

Mathematically, it is written as :

m is the mass of an object

v is the velocity

So, it is clear that the momentum of an object is directly proportional to its velocity.

The statement "as a moving object's velocity decreases, its momentum decreases" is absolutely true.

The following cause that is notconsidered in the formation of a Dust Bowl is the lack of farmers in Oklahoma.The answer is letter B. in fact, the number of farmers increases due to thehigh grain prices of Worl War I that encourages farmers to plow millions ofacres of natural grass to plant wheat.

Answer:

With the advent of pesticides, minerals in the ground were leached.

If you are bombarded with 1.00 mol of photons with a wavelength of 370 nm, you are being subjected to 322 kJ/mol of energy.

The energy of a photon is given by the equation:

E = hc/λ

where:

h = Planck's constant = 6.626 x J s

c = speed of light = 2.998 x m/s

λ = wavelength of the radiation

To find the energy of a mole of photons, we need to multiply the energy of a single photon by Avogadro's number (6.022 x ).

First, we need to convert the wavelength of the radiation from nanometers to meters:

370 nm = 370 x m

Now, we can use the equation to calculate the energy of a single photon:

E = hc/λ

E = (6.626 x J s) x (2.998 x m/s) / (370 x m)

E = 5.35 x J

Next, we can calculate the energy of a mole of photons:

(5.35 x J/photon) x (6.022 x photons/mol) = 3.22 x J/mol

Finally, we can convert the energy to kilojoules per mole of photons:

3.22 x J/mol = 322 kJ/mol

By using the relation between period and frequency, we conclude that the period of the fork is0.0023 seconds.

What is the period of the vibrating fork?

We know that the relation between period and frequency is:

T = 1/f

where T is the period and f is the frequency.

In this case, we know that the frequency of the fork is 440 Hz, where:

1 Hz = 1/s

Then the period of the fork will be:

T = 1/(440 Hz) = (1/440) s = 0.0023 s

Meaning that each complete vibration of the fork takes 0.0023 seconds.
