Aspaceship is moving in a straight line away from earth at 0.80c, measured relative to earth. it launches a missile that moves away from the spaceship in the forward direction at 0.60c, relative to the ship. relative to earth, what is the speed of this missile?

a. c
b. greater than c but less than 1.4c
c. 1.4 c
d. greater than 0.80c but less than c

c- 1.4 c

Explanation:

Velocity of the space ship v = 0.80 c velocity of the missile v ' = 0.60 c

then the velocity of the missile measured by observer is v + v'

0.80c + 0.6c =1.4c

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
