Answer:

It provides explanations for observations which can change.

Explanation:

Scientific laws are theories that have been tested, proven, and adopted as laws. Scientists experiment to test a theory wherein Data is collected, analyzed. After multiple testing, the result is concluded and if the theory is proven, it is adopted as law.

According to Kepler's law, planets move around stars in elliptical orbits. It was a theory earlier but after testing it and proving it, it was accepted as a law. It will provide the explanation for any observations related to the motion of the planets.

zimovet [89]

Answer: 1 m/s^2

Explanation:

n= w+ma

n= Mg+Ma

7020 = (650)(9.8)+650a

7020 = 6370+ 650a

650=650a

Radda [10]

Answer:

E = 1.38 x 10⁸ eV = 138 MeV

Explanation:

The energy associated with the given wavelength can be found from the following formula:

E = \frac{hc}{\lambda}

where,

E = Energy of electron = ?

h = Plank's Constant = 6.625 x 10⁻³⁴ J.s

c = Speed of Light = 3 x 10⁸ m/s

λ = wavelength = 9 fm = 9 x 10⁻¹⁵ m

Therefore,

E = \frac{(6.625\ x\ 10^{-34}\ J.s)(3\ x\ 10^8\ m/s)}{9\ x\ 10^{-15}\ m}\\\\E = (2.21\ x\ 10^{-11}\ J)(\frac{1\ eV}{1.6\ x\ 10^{-19}\ J})

<u>E = 1.38 x 10⁸ eV = 138 MeV</u>

Which interaction does not take place due to field forces?
amid [387]

The interaction that does not take place due to field forces is the interaction between a pen and paper while you write.

<h3>What is the gravity law?</h3>

Gravity law is a well-established scientific theory that states objects can attract each other according to their masses.

This theory (gravity law) was developed by Sir Isaac Newton to explain the movement of objects.

In conclusion, the interaction that does not take place due to field forces is the interaction between a pen and paper while you write.
