Answer:
Explanation:
From the question we are told that:
Length 
Width 
Velocity of Car A 
Velocity of Car B 
Distance traveled by car A before car B moves
Therefore total distance traveled at same time interval
Where
Total distance=Perimeter of rectangle
Therefore
Generally the equation for time taken to meet is mathematically given by
Where
Relative speed = Speed of car A +Speed of car B
Therefore the time taken to meet
Actually, they're not. There's a group of stars and constellations arranged
around the pole of the sky that's visible at any time of any dark, clear night,
all year around. And any star or constellation in the rest of the sky is visible
for roughly 11 out of every 12 months ... at SOME time of the night.
Constellations appear to change drastically from one season to the next,
and even from one month to the next, only if you do your stargazing around
the same time every night.
Why does the night sky change at various times of the year ? Here's how to
think about it:
The Earth spins once a day. You spin along with the Earth, and your clock is
built to follow the sun . "Noon" is the time when the sun is directly over your
head, and "Midnight" is the time when the sun is directly beneath your feet.
Let's say that you go out and look at the stars tonight at midnight, when you're
facing directly away from the sun.
In 6 months from now, when you and the Earth are halfway around on the other
side of the sun, where are those same stars ? Now they're straight in the
direction of the sun. So they're directly overhead at Noon, not at Midnight.
THAT's why stars and constellations appear to be in a different part of the sky,
at the same time of night on different dates.
Answer:
3.39724 seconds
23.0824792352 m, 101.917520765 m
13.58896 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
The equation of motion will be
The time at which the cars collide is 3.39724 seconds
Car B traveled 23.0824792352 m and Car A traveled 125-23.0824792352 = 101.917520765 m
The speed of car B is 13.58896 m/s
I think the answer is 3, population.
To calculate the work, we use:
W = PΔV
W = 10(0.4-0.01)
W = 3.9 L*atm
W = 3.9 * 101.3
W = 395.07 Joules
