An open system is
when there is a transfer of energy and matter with its surroundings.
A closed system is
where there is a transfer of energy, may it be heat or work, but not matter
with its surroundings.
An isolated system
is where there is no transfer of energy or matter with its surroundings.
I am slightly unsure on the question, but if you are asking what kind of "statement" is "r<em>oller coasters are the best use of Newton's laws of motion</em>" then the following should answer your question:
Answer:
An opinion.
Explanation:
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
The statement, "Roller coasters are the best use of Newton's laws of motions" is an opinion because it is not based on any evidence, facts, or proof to back it up.
Answer:isotopes of an element has same number of proton but different number of neutron.
Explanation:
Isotope: The atoms of element having same atomic number but different mass number are called isotope.
Hydrogen has three isotopes called as
1.protium
2.duetrium
3.tritium
All of the isotopes of hydrogen have same atomic number but different masses 1,2,3 respectively.
Isotopes have same outermost shells there for having same chemical properties.
Isotopes have different nuclie due which they have different physical properties.
Tritium the 3rd isotop having diffrent prton to neutron ration emitts radiation there it in traces.
Answer:
f = 0.534×10⁻² Hz
Explanation:
Given data:
Frequency of wave= ?
Wavelength of wave = 5.62×10¹⁰ m
Solution:
Formula:
Speed of wave = wavelength × frequency
Speed of wave = 3×10¹⁷ nm/s
λ = 5.62×10¹⁰m×10⁹ nm/1 m = 5.62×10¹⁹ nm
Now we will put the values in formula.
3×10¹⁷ nm/s = 5.62×10¹⁹ nm × f
f = 3×10¹⁷ nm/s / 5.62×10¹⁹ nm
f = 0.534×10⁻² s⁻¹ or
f = 0.534×10⁻² Hz
