Answer: Vector quantity is a measurement that has both magnitude and direction.
Explanation:
Vector quantity is a measurement that has both magnitude and direction. Examples are force, acceleration, displacement and velocity.
First we can calculate the average speed v in km/h by the equation v=s/t where s is the distance traveled and t is the time:
First we turn time into seconds and divide by 3600 to get time t in hours is:
t=13*3600 s + 4*60 s + 58 s= 47098 s and that is:
t=47098s/3600s=13.08278 hours
So v=1633.8/13.08278=124.88 km/h
To get speed in m/s we simply turn kilometers into meters and hours into seconds:
s=1633.8 km *1000 = 1633800 m
t=13*3600s + 4*60 s + 58 s=46800 s + 240 s + 58 s=47098 s
v=s/t=1633800/47098=34.67 m/s
So average speed in km/h is v=124.88 km/h and in m/s is v= 34.67 m/s.
Answer:
The event horizon of a black hole can be thought of either as the place around the black hole where the speed you need to escape becomes greater than the speed of light or as the place where the warping of spacetime around a collapsed star becomes so great that all straight lines pointing outward actually become curved paths bringing you back in. Only black holes have event horizons, so our Sun, which is a star in happy main-sequence equilibrium, cannot have one.
