147.09975 newton meters per second
Answer:
1.5 x 10¹⁸hz
Explanation:
Given parameters:
Wavelength = 2 x 10⁻¹⁰m
Unknown:
Frequency = ?
Solution:
To find the frequency, use the expression below;
V = f x wavelength
V is the speed of light = 3 x 10⁸m/s
f is the frequency
Now;
Insert the parameters
3 x 10⁸ = 2 x 10⁻¹⁰ x frequency
Wavelength = = 1.5 x 10¹⁸hz
The answer is the Goldilocks Zone.
The Goldilocks zone refers to a zone around the star that is habitable. This means that it is not too hot and not too cold.
The Kuiper belt is located beyond Neptune. The Oort cloud is even further out in the solar system, past Pluto. The asteroid belt is located in between the orbit of Mars and Jupiter.
Answer:
Explanation:
Given
radius of neutron star
Centripetal force on material having mass m is given by
Gravitational Force between neutron star and mass m is
,where M=mass of Neutron star
equating centripetal Force and Gravitational Pull
<span>The amount of heat energy needed to increase the temperature of a substance by </span>
<span> is given by:
</span>
<span>
where m is the mass of the substance, Cs is its specific heat capacity and </span>
<span> is the increase in temperature of the substance.
In this problem, we have a certain mass m of gold, with specific heat capacity </span>
<span>, to which we add Q=2825 J of energy. Its temperature increases by </span>
<span>. Therefore, if we re-arrange the previous equation, we can find the mass of the block of gold:
</span>
<span>
So, the correct answer is B.</span>
