Adding both distances together, you get a total of 1800 miles. With the total travel time of 4 hours, you divide the distance traveled by the time it took. so 1800/4=450 mph
The velocity after 3 s is 12 m/s rightward
Explanation:
The motion of the rocket is a motion at constant acceleration, therefore we can apply suvat equations:
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time interval
For the rocket in this problem:
u = 0 (the rocket starts from rest)
t = 3 s
rightward is the acceleration
Solving for v, we find the final velocity:
(rightward)

Answer:
The image of everything in front of the mirror is reflected backward, retracing the path it traveled to get there. Nothing is switching left to right or up-down. Instead, it's being inverted front to back. ... That reflection represents the photons of light, bouncing back in the same direction from which they came
Explanation:
The area directly above the light bulb is warmest because of convection. Convection is a heat transfer by mass motion of fluid (like air), and it convection<span> above a hot surface occurs because hot air expands, becomes less dense, and rises. The statement can be supported by the ideal gas law.</span>
