Answer:
θ= 5 radian
Explanation:
Given data:
Radius r = 0.70 m
Initial angular speed ω_i = 2rev/s
Time t = 5 s
Final angular speed ω_f =0
so we have angular displacement

putting values
= 5 rad
Answer:
A. moral development progressed through distinct, qualitatively different stages.
Explanation:
Kolhberg’s theory of moral development states that we progress through three levels of moral thinking that build on our cognitive development.
Answer
given,
diameter of planet = 1.8 x 10⁷ m
radius of planet = 0.9 x 10⁷ m
time period = 22.3 hours
the planet orbits 2.2 x 10¹¹ m period of 402 earth days.
acceleration= 12.2 m/s²
we know



M_p = 1.48 x 10²⁵ Kg
b) Formula to calculate the mass of star


M_s = 5.22 x 10³³ Kg
Answer:
.17Hz
Explanation:
The formula for frequency is f= 1/T , where T is the period.
f = 1/6 and 1/6 ≈ .17
