Answer:
Explanation:
h = ½at²
t = √(2h/a)
t = √(2(32)/9.8)
t = 2.5555062... 2.6 s
Answer: 250 N
Use equation for work
W=F*d
d=2m
W=500J
F=?
-----------------------
W=Fd
F=W/d
F=500J/2m
F=250N

Answer
Given,
Time period of star,T = 3.37 x 10⁷ s
Radius of circular orbit,R = 1.04 x 10¹¹ m
a) Angular speed of the planet
b) tangential speed
v = 1.94 x 10⁴ m/s
c) centripetal acceleration magnitude
a = 3.62 x 10⁻³ m/s²
And the bigger intensity
