The height of the tower and the distance from its base form a right angle triangle. Thus,
tan(∅) = height / base
tan(28.81) = height / 1,000 m
height = 549.98 meters
A wave is a rhythmic movement that carries energy through space or matter.
Umm do u want me to answer this’ll
Answer:
a)
b)
c)
Explanation:
a) The angular velocity is related to the centripetal acceleration by the formula , which for our purposes we will write as:
Since <em>we want this acceleration to be 1.5 times that due to gravity</em>, for our values we will have:
b) 1 rpm (revolution per minute) is equivalent to an angle of radians in 60 seconds:
Which means <em>we can use the conversion factor</em>:
So we have (multiplying by the conversion factor, which is 1, not affecting anything but transforming our units):
c) The centripetal force will be given by Newton's 2nd Law F=ma, so on the centripetal direction for our values we have:
