If two spaceships leave the earth in opposite directions at three fourths the speed of light earth relative and one ship attempts to send a laser beacon to the other ship will the beacon ever be seen?

Yes. If there are eyes on board the other spaceship.

No, the laser beam would never reach the other spaceship because the speed of light is constant and finite. As the two spaceships are moving away from each other at speeds close to the speed of light, the distance between them would be increasing faster than the laser beam could travel.

Why two trains on different tracks do not pass each other with same speed?
If two trains on different tracks are moving at the same speed, they will pass each other. However, if they are moving in opposite directions on parallel tracks, it may appear that they are not passing each other since their relative speed is zero. This is because their velocities relative to each other cancel out.
How do you calculate the relative speed of two trains passing each other?
If two trains are passing each other the relative speed can be found by adding the individual speeds of the two trains. This applies if the trains are passing each other in opposite directions. Should one be passing the other and both be moving in the same direction, the difference of the individual speeds would be the relative speed of the trains.
What is meant by negative vector?
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
Velocities in opposite directions combine by what?
Vector addition of velocities would be if something like you were on an escalator, which is going down, and you tried to run up the escalator. So if the escalator is moving down at a rate of 5 ft/sec and you run up at 13 ft/sec (relative to the escalator) then the net velocity relative to the Earth is 8 ft/sec up. So you just subtract, because the two vectors are in the same line. OK so really the direction is at an angle (rather than 'up'). The larger velocity direction will determine the net direction. If you were walking up the escalator at 3 ft/sec (relative to the escalator), then your net velocity is 2 ft/sec down.
Does a proton have a bigger charge than an electron?
No, the absolute charge of proton is equal to the absolute charge of electrons. however, their relative charge is opposite in sign.
What is the abbreviation for relative?
relative, opposite of absolute
What is the opposite of relative location?
Relative location.
Damage is more when two bodies collide from opposite directions than when they collide at any other angle.Is it due to the momentum of the objects or their relative velocities?
It is due to the momentum of the two bodies.
What is the opposite of locate?
Relative location.
If 2 cars start 100 miles apart drive in a straight line in opposite directions 1 is going 60 mph and 1 is going 45 mph when will they collide?
Never, since they are travelling in opposite directions.. . . but probably not the one the algebra book's authors intended....If you assume that "opposite directions" means the cars are travelling towards each other, their closing speed (i.e. relative speed) is 105 mph. That means they'll meet in 100/105 hours, or slightly more than 57 minutes.
What is the relative movement along the San Andreas Fault?
The San Andreas Fault is a transform fault (also known as a strike-flip fault). It is where two plates are sliding past each other in opposite directions.
Describe the motions of Charon relative to the horizon?
they are relative because of the comets tail. opposite the sun. so they are relative upward
Relative and absoute location have in common?
They are both used to find directions.
What do you think will give a greater damage a car hitting another moving car or car car hitting a steady car?
The amount of damage relates to the relative motion of the two cars. So, if the cars are moving in opposite directions when they collide, the relative motion and the resulting damage is greater; if they are moving in the same direction, then the relative motion and the resulting damage is less. A motionless car is intermediate between a car moving in the same direction and a car moving in an opposite direction.
What is absolute and relative measurement?
absolute is exactly where it is on the globe and relative is like your telling someone directions like goergia is east of alabama.

What directions do the plates move relative to one another at a divergent plate boundary?
they move away form each other, so what ever the direction the plates are the move the apposite direction away
