Answer:
<h2>
5.3 m</h2>
Explanation:
The standard film size for one popular camera was<u> 79 mm square</u>.
The film was <u>116 mm behind the lens</u>.
If you wanted a picture of your<u> 1.8-m-tall friend to fill half the frame</u>,
find:
how far away from you did she need to stand?
solution:
the other person called friend is 1.8 m tall (1,800mm) stood from the other side to fill up half of the frame of 79mm / 2 = 35 mm.
where the film behind the lens is 116mm as given.
so its a ratio and proportion:
<u>1800 mm </u> = <u> 39.5 mm </u>
x 116 mm
39.5 (x) = 1800 (116)
x = <u> 208,800</u>
39.5
x = 5286 mm * <u> 1 m </u>
1000 mm
x = 5.3 m
Answer:
99.95%
Explanation:
A double pulsar system named PSR J0737-3039A/B in Puppis constellation was discovered in the year 2003. Pulsars are second most densest object in the universe after black holes and they emit radio waves at regular intervals. This pair presented a great and natural setup to test the Theory of General Relativity presented by Einstein in 1915. In this theory Einstein had presented a set of equations on how the space-time fabric will be curved because of the very dense objects such as Neutron stars. It also predicted how the gravitational waves are created because of stars orbiting each other.
A team of astrophysicists led by Michael Kramer, conducted a study on how these gravitational waves will impact the time in which the radio waves emitted by pulsars will reach Earth. The result of the study proved the theory of General Relativity to be accurate up to 99.95%.
