In astronomy circumpolar constellations are those ones which never set from viewer's perspective like ursa minor, cassiopiea etc.
Because of the rotation of the Earth and its orbit around the Sun, we divide the stars and constellations into two groups. Some stars and constellations never rise nor set, and they are called circumpolar. All the rest are divided into seasonal stars and constellations. Which stars and constellations will be circumpolar and which seasonal depends on your latitude.
Answer:
its point Y because the dot that represents Y is cose to s and can make a chan reaction
If you know the real modulus of the cable (Y), the length, and the area (based on the radius), you can compute the spring constant, k = AE/L. Then, if you know the force used, you can compute the displacement, using F = kd, or d = F / k = FL/(AE). Our answer should work out to units of length. So,
d = 803 N * 9.06 m / [pi*(0.574 cm)^2 * 2.0 x 10^11 N/m^2]
d = 3.5 x 10^-8 Nm^3 / (cm^2 * N)
d = 3.5 x 10^-8 m^3 / cm^2 * (100 cm / 1 m)^2
d = 3.5 x 10^-4 m
Heat rises, and it is warmer at the equator, so I think warm air would rise at the equator and move towards the cooler poles.
Velocity of an object is given as
now we have
time = 3 hours
now from above formula
so its velocity is 40 mph and its a vector quantity whose direction is towards NORTH
correct answer is B
