Melting, boiling, and freezing are state changes!
Hope this helps! Any questions please just ask! Thank you so much!
I believe the correct answer is A, Wave 1 has a longer wavelength and a higher amplitude than wave 2. Both A and B are transverse wave, therefore, the wavelength is the distance between two successful crest (highest point) or two successful trough (lowest point). In this case, wave 1 has a longer wavelength than wave 2. Amplitude is the maximum displacement of particles in a wave on either side from the equilibrium point. From the diagram wave 1 as a higher amplitude compared to wave 2.

Explanation:
The Schwarzschild radius can be calculated as follows:
![R=\frac{GM}{c^2}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7BGM%7D%7Bc%5E2%7D)
Where, <em>G</em> is the gravitational constant, <em>M</em> is the mass and <em>c</em> is the speed of light.
Mass of sun is 1.98×10³⁰ kg
![R=\frac{G\times 7.5M_{sun}}{c^2}\\ R=\frac{6.67\times10^{-11}\times(7.5\times1.98\times10^{30})}{(3\times10^8)^2}\\ \Rightarrow R=1.1\times10^{4}m](https://tex.z-dn.net/?f=R%3D%5Cfrac%7BG%5Ctimes%207.5M_%7Bsun%7D%7D%7Bc%5E2%7D%5C%5C%20R%3D%5Cfrac%7B6.67%5Ctimes10%5E%7B-11%7D%5Ctimes%287.5%5Ctimes1.98%5Ctimes10%5E%7B30%7D%29%7D%7B%283%5Ctimes10%5E8%29%5E2%7D%5C%5C%20%5CRightarrow%20R%3D1.1%5Ctimes10%5E%7B4%7Dm)
Answer:
Motion may be divided into three basic types — translational, rotational, and oscillatory.
Explanation:
Answer:
2.30 × 10⁻⁸ N if the two electrons are in a vacuum.
Explanation:
The Coulomb's Law gives the size of the electrostatic force
between two charged objects:
,
where
is coulomb's constant.
in vacuum.
and
are the signed charge of the objects.
is the distance between the two objects.
For the two electrons:
.
.
.
The sign of
is negative. In other words, the two electrons repel each other since the signs of their charges are the same.
