Solution :
Acceleration due to gravity of the earth, g
Acceleration due to gravity at 1000 km depths is :
= 8.23 m/s
Acceleration due to gravity at 2000 km depths is :
= 6.73 m/s
Acceleration due to gravity at 3000 km depths is :
= 5.18 m/s
Acceleration due to gravity at 4000 km depths is :
= 3.64 m/s
Answer:
539.19 m/s , 459.83 m/s , 2156.78 m/s
Explanation:
The formula for the rms speed is given by
Where, R be the gas constant, T be the absolute temperature and M be the molecular mass of the gas
R = 8.314 in SI units
T = 100°C = 100 + 273 = 373 K
For Oxygen:
M = 32 g = 0.032 kg
vrms = 539.19 m/s
For carbon di oxide:
M = 44 g = 0.044 kg
vrms = 459.83 m/s
For hydrogen:
M = 2 g = 0.002 kg
vrms = 2156.78 m/s
The child on a swing can be modeled as a simple pendulum. The period of a simple pendulum is given by
Hello!
Recall the equation for gravitational force:
Fg = Force of gravity (N)
G = Gravitational constant
m1, m2 = masses of objects (kg)
r = distance between the objects' center of masses (m)
There is a DIRECT relationship between mass and gravitational force.
We are given:
If we were to double one mass and triple another, according to the equation:
Thus:
