Answer:
= 3521m/s
The tangential speed is approximately 3500 m/s.
Explanation:
F = m * v² ÷ r
Fg = (G * M * m) ÷ r²
(m v²) / r = (G * M * m) / r²
v² = (G * M) / r
v = √( G * M ÷ r)
G * M = 6.67 * 10⁻¹¹ * 5.97 * 10²⁴ = 3.98199 * 10¹⁴
r = 32000km = 32 * 10⁶ meters
G * M / r = 3.98199 * 10¹⁴ ÷ 32 * 10⁶
v = √1.24 * 10⁷
v = 3521.36m/s
The tangential speed is approximately 3500 m/s.
The skier’s change in velocity is 8.33.../8.4 m/s.
21/63= 0.33...
0.33...x 25 s = 8.33.../8.4 m/s
Answer:
Correct answer:
As the temperature increases, the kinetic energy of the molecules increases.
Explanation:
The relation between kinetic energy and temperature in an ideal gas which we will take as an example is given by the following formula:
Ek = 3/2 N k T ,
where N is the total number of molecules a k is a Boltzmann constant.
If we assume that the total number of molecules is a constant, kinetic energy only depends on temperature.
