Answer:
a) E = 6.4 1019 J b) v = 0.69 10⁴4 m / s
Explication
a) convert E = 4.0 eV
1 eV = 1.6 10⁻¹⁹ J
E = 4.0 eV (1.6 10⁻¹⁹ J / 1 eV)
E = 6.4 10⁻¹⁹ J
b) Suppose we have a frontal shock and all the kinetic energy of oxygen is transferred to Cs
Ei = K = ½ m v²
Ef = 6.4 10⁻¹⁹ J
½ m v² = 6.4 10⁻¹⁹
The oxygen mass of the periodic table is
PA = 15,999 u
1u = 1.660 10⁻²⁷ kg
Pa = 15,999 1,660 10⁻²⁷ kg
m= Pa = 26,558 10⁻²⁷ kg
Let's calculate the speed
v2 = 2 / m 6.4 10⁻¹⁹
v2 = 2 / 26,558 10⁻²⁷ 6.4 10⁻¹⁹ =
v = √0.4819 10⁸
v = 0.69 10⁴4 m / s
It's either a comet or asteriod
Answer:
The vertical component of the velocity is about 16 m/s.
Explanation:
The vertical component is the magnitude of the velocity reduced by the sinus of the angle 53 degrees. So
Answer:
Monochronic.
Explanation:
This view is called as Monochronic.
The dictionary definition of Mono-chronic is that Monochronic people just like to do one thing at a time. They respect a certain uniformity and sense of being a suitable place and time for different activities. They don't esteem interruptions. It has been generally observe that their focus and productivity remains higher than the polychronic.( Those we are comfortable with performing multiple task at a time)
