4) They have non-moving magnetic fields.
Nope.... Weight of object changes due to change in gravity but mass remains constant...
Answer: T = 5068 s
Explanation:
Given
Radius of the earth, r = 6378.1 km
Centripetal acceleration, g = 9.81 m/s²
Period of rotation, T = ?
a = w²r, where
a is the centripetal acceleration
w is the angular velocity
r is the radius
9.81 = w² * 6378.1*10^3
w² = 9.81 / 6378.1*10^3
w² = 1.538*10^-6
w = 1.24*10^-3 rad/s
To get the period of the earth, we use the formula
w = 2π / T, so that
T = 2π / w
T = (2 * 3.142) / 1.24*10^-3
T = 6.284 / 1.24*10^-3
T = 5067.74 s
Therefore, the earth would rotate at a period of 5068 s or 1 hour and 24 minutes
Hello
When all the stages of scientist method being covered. After that, you can to modify any theory according to the observations, measures, etc.
