Use Einstein's special-relativity equation Upper R Subscript a Baseline equals Upper R Subscript f Baseline StartRoot 1 minus left parenthesis StartFraction v Over c EndFraction right parenthesis squared EndRoot , which gives the aging rate of an astronaut, Upper R Subscript a, relative to the aging rate of a friend, Upper R Subscript f, on Earth. In this formula, v is the astronaut's speed and c is the speed of light. Suppose an astronaut is moving at 40% of the speed of light. Substitute 0.4c for v, the astronaut's velocity, in the equation. What is the aging rate of the astronaut relative to a friend on Earth? If the astronaut was gone for 92 weeks, approximately how many weeks have passed for the friend?
What is the aging rate of the astronaut relative to a friend on Earth?

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.

the answer is two. hope this !

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

i believe it is 2

lolll
