To solve this problem it is necessary to apply the concepts related to the relationship between tangential velocity and centripetal velocity, as well as the kinematic equations of angular motion. By definition we know that the direction of centripetal acceleration is perpendicular to the direction of tangential velocity, therefore:
Where,
V = the linear speed
r = Radius
Angular speed
The angular speed is given by
Replacing at our first equation we have that the centripetal acceleration would be
To transform it into multiples of the earth's gravity which is given as 
the equivalent of 1g.
PART B) Now the linear speed would be subject to:
Therefore the linear speed of a point on its edge is 51.05m/s
The Kelvin scale is also called absolute zero scale
Explanation:
true
Answer:
v = 9.936 m/s
Explanation:
given,
height of cliff = 40 m
speed of sound = 343 m/s
assuming that time to reach the sound to the player = 3 s
now,
time taken to fall of ball
t = 2.857 s
distance
d = v x t
d = v x 2.875
time traveled by the sound before reaching the player
distance traveled by the wave in this time'
r = 0.143 x 343
r= 49.05 m
now,
we know.
d² + h² = r²
d² + 40² = 49.05²
d =28.387 m
v x 2.875=28.387 m
v = 9.936 m/s
Answer:
I strongly feel its 1.
Explanation:
the expectancy theory of motivation is basically getting an reward for a great accomplishment so 1 would make the most sense in this question, lmk if its wrong
Answer:
they stick together when they get close
