A lighthouse is located on a small island 2 km away from the nearest point P on a straight shoreline and its light makes 9 revolutions per minute. How fast is the beam of light moving along the shoreline when it is 1 km from P ? (Round your answer to one decimal place.)

The speed of light moving along the shoreline when it is 1 km from P is 2.1064 km

Step-by-step explanation:

We are given that a point 1 km from point P on the shoreline would  form a a right triangle with the lighthouse, point P, and the point 1 km from  point P.

The distance from that point to the lighthouse would be the hypotenuse.

That would also be the radius of the circle the beam of light is making at that point.

To find the hypotenuse

Circumference =

The beam of light is making at point 14.05 km away

One revolution: sec per revolution

Speed =

Hence The speed of light moving along the shoreline when it is 1 km from P is 2.1064 km

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
