The gravitational force on two objects can be determined by the following equation:

$F=G\frac{m_{1}m_{2}}{r^2}$

Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:

$F=6.67x10^{-11}\frac{(1.99x10^{30})(1.90x10^{27})}{(7.78x10^{11})^2}$

$F=4.1665x10^{23}$

F=4.17x10^23 N

The wavelength of an EM wave is 800 nm. Calculate its frequency, angular frequency, wavenumber, wave vector amplitude, energy, a

irga5000 [103]

Answer:

Given: Wavelength (λ) = 800 nm

Frequency $\nu=\frac{c}{\lambda} \Rightarrow \nu = \frac{3\times10^8}{800\times 10^{-9}} =3.75\times10^{14} Hz$

Angular frequency $\omega=2\pi \nu \Rightarrow \omega = 2\pi 3.75\times10^{14} = 23.55\times10^{14} rad/s$

Wavenumber, $k=\frac{2\pi}{\lambda} \Rightarrow k =\frac{2\pi}{800\times 10^{-9}}=7.85\times 10^6m^{-1}$

wave vector amplitude |k| = k = $7.85\times 10^6m^{-1}$

energy, $E = h \nu \Rightarrow E = 6.63\times 10^{-34}\times 3.75\times10^{14} = 24.86\times 10^{-20}J$

momentum, $p=\frac{h}{\lambda} = \frac{6.63\times 10^{-34}}{800\times 10^{-9}}= 8.28\times 10^{-28}Ns$

A person is straining to lift a large crate, without success because it is too heavy. We denote the forces on the crate as follo

Evgen [1.6K]

Answer:

P + C = W if in equilibrium?

P + C - W = 0; P + C = W

Explanation:

Action and reaction are equal and opposite according to newton's third law of motion. a force is that which tends to change a body's state of rest or uniform motion in a straight line, recall

P is the upward force the person exerts on the crate,

C is the vertical contact force exerted on the crate by the floor,

W is the weight of the crate

let the sum of upward forces be on the left hand side of the equation and the sum of downward forces on the right hand side.

P+C=W

P+C-W=0 if they are in equilibrium

the forces are related by the above.

Which statements describe the process of scientific inquiry? Check all that apply.

velikii [3]

I believe that you forgot to add the choices. However, I will just tell you what is the process of scientific inquiry and you can choose the best match from the choices you have.

Scientific inquiry is mainly the process of developing a meaningful explanation to a certain phenomenon or a question from the natural world. This process involves collecting data, forming a hypothesis and testing the results of this hypothesis. These results whether confirm or reject the hypothesis you made you made.

Scientific inquiry has seven main sub-process, these processes are as follows:
1- Figuring out the problem through observation
2- To do some research to gather more information about the problem and how to solve it
3- To develop your hypothesis on how to solve this problem
4- To test your hypothesis through experiments and observation
5- analyzing the results of your testing through graphs, tables, organizing data,....elc
6- to draw a conclusion based on these results. The conclusion will either confirm or reject your hypothesis
7- Just pass-on your results
