Answer: The origin might be from MARS
Explanation: Meteorites origin are either from Asteroid, Moon or Mars. Their origin is usually classified according to their age after using radioisotope dating. Meteorites that originate from Mars are between the age of 4.5 billion to 200 million years. Since the meteorite in question is only a billion years old, the origin would be from Mars.
Explanation:
Given:
v₀ = 0 m/s
a = 2.50 m/s²
t = 4 s
Find: v
v = at + v₀
v = (2.50 m/s²) (4 s) + 0 m/s
v = 10 m/s
Explanation:
Given that,
The kinetic energy of the electron, ![K=1.67\ keV=1.67\times 10^3\ eV](https://tex.z-dn.net/?f=K%3D1.67%5C%20keV%3D1.67%5Ctimes%2010%5E3%5C%20eV)
Radius of the orbit, r = 37.4 cm = 0.374 m
To find,
(a) the electron's speed, (b) the magnetic field magnitude, (c) the circling frequency, and (d) the period of the motion.
Solve,
We know that, ![1\ eV=1.6\times 10^{-19}\ J](https://tex.z-dn.net/?f=1%5C%20eV%3D1.6%5Ctimes%2010%5E%7B-19%7D%5C%20J)
![K=1.67\times 10^3\times 1.6\times 10^{-19}\ J=2.67\times 10^{-16}\ J](https://tex.z-dn.net/?f=K%3D1.67%5Ctimes%2010%5E3%5Ctimes%201.6%5Ctimes%2010%5E%7B-19%7D%5C%20J%3D2.67%5Ctimes%2010%5E%7B-16%7D%5C%20J)
(a) The formula of the kinetic energy is given by :
![K=\dfrac{1}{2}mv^2](https://tex.z-dn.net/?f=K%3D%5Cdfrac%7B1%7D%7B2%7Dmv%5E2)
v is the speed if electron
m is the mass of electron
![v=\sqrt{\dfrac{2K}{m}}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cdfrac%7B2K%7D%7Bm%7D%7D)

(b) Let B is the magnitude of magnetic field. On the circular path the magnetic field is given by :
![B=\dfrac{mv}{qr}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7Bmv%7D%7Bqr%7D)
![B=\dfrac{9.1\times 10^{-31}\times 2.42\times 10^7}{1.6\times 10^{-19}\times 0.374}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B9.1%5Ctimes%2010%5E%7B-31%7D%5Ctimes%202.42%5Ctimes%2010%5E7%7D%7B1.6%5Ctimes%2010%5E%7B-19%7D%5Ctimes%200.374%7D)
![B=3.68\times 10^{-4}\ T](https://tex.z-dn.net/?f=B%3D3.68%5Ctimes%2010%5E%7B-4%7D%5C%20T)
(c) Let T is the time period of the motion. It is given by :
![T=\dfrac{2\pi r}{v}](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B2%5Cpi%20r%7D%7Bv%7D)
Circling frequency is given by :
![f=\dfrac{1}{T}=\dfrac{v}{2\pi r}](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7B1%7D%7BT%7D%3D%5Cdfrac%7Bv%7D%7B2%5Cpi%20r%7D)
![f=\dfrac{2.42\times 10^7}{2\pi \times 0.374 }](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7B2.42%5Ctimes%2010%5E7%7D%7B2%5Cpi%20%5Ctimes%200.374%20%7D)
![f=1.02\times 10^7\ Hz](https://tex.z-dn.net/?f=f%3D1.02%5Ctimes%2010%5E7%5C%20Hz)
(d) The period of motion,
![T=\dfrac{1}{f}](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B1%7D%7Bf%7D)

The vertical velocity is the greatest at C, where it is closest to the ground.
The projectiles horizontal velocity stays constant through the entire thing, so it is the same for A, B, and C.
The projectiles speed is the greatest at C, because both its vertical and horizontal components of its velocity is greater than or equal to that of the other two points.
