Develop a qualitative understanding for the effects of the tilt of Earth's rotation axis on the length of days and solar radiation received throughout the year.

Part I
Notice that in each of the pictures, different parts of the poles are illuminated. In the first image, the north pole is present. Then the north pole begins to retreat into darkness and the south pole emerges at the bottom of the image. In December only the Antarctic is seen, and the north pole is now in darkness.

At equinoxes (September and March) everywhere on the Earth has a 12-hour day and, consequently, a 12-hour night except the north pole and the south pole where the sun is exactly at the horizontal. So the equator at these times will be in the center of the image. You need to choose a location along the equation. You could choose a city in equatorial Guinea, such as Aconibe. Its latitude is 1°18' N.

In June, the Sun is more directly above a location north of the equator. From the image, you can see that central America and north Africa ...

Solution Summary

Develop a qualitative understanding for the effects of the tilt of Earth's rotation axis on the length of days and solar radiation received throughout the year.

What is the magnitude and direction of the centripetal acceleration due to theearth'srotation at a location near Kansas City at 38 degrees latitude? I believe the answer is 2.66x10^-2 m/s^2, towards theearth'srotationaxis. I need to see all formulas involved.

Please explain for me how to do this question.
Earth is a spherical object, which completes a full rotation every 24 hours. How long should the day on Earth be so that an object at the equator is able to float freely above the ground?

1. If theaxis of the Earth were tilted at 50 instead of 23.5, would the Summers in Europe be longer and hotter ? Explain.
2. Why do we always see the same face of the Moon from the Earth?
3. If a lunar eclipse occurs in January, can it be seen from the South Pole? Explain.

The L-shaped object in Figure 11-27 consists of three masses connected by light rods. See attached Figure.
(a) What torque must be applied to this object to give it an angular acceleration of 1.27 rad/s2 if it is rotated about the x axis?
_________N?m
(b) What torque must be applied to this object to give it an angular acc

A projectile of mass m is fired from the surface of the earth at an angle A from the vertical. The initial speed Vo is equal to the square root (GMe/Re). How high does the projectile rise? Neglect air resistance and theearth'srotation. (Hint: It is probably easier to apply the conservation laws directly instead of using orbit

Please help with the following problem:
Contrast the sidereal and solar days. How, and by roughly how much, would the length of the solar day change if Earth'srotation were suddenly to reverse direction?

In terms of radians and X, what would be the specifications of the anlges for trigonometric points which result from the following transformations of the trigonometric point P(X)? (Work these out on a diagram of the unit circle)
1) A reflection y = x followed by a rotation through pi
2) A reflection in y = -x
3) A refle

A projectile is fired horizontally along theearth's surface. Show that to a first approximation the angular deviation from the direction of fire resulting from the Coriolis force varies linearly with time at a rate of cos wq, where q is the angular frequency of theEarth'srotation and is the latitude angle, the direction of de

A test tube filled with liquid of uniform density rho, as shown in the figure (see attachment), is spun in a centrifuge with angular frequency w. The test tube lies perpendicular to theaxis of rotation of the centrifuge. The pressure in the fluid at the distance r0 from theaxis of rotation is p0. You may ignore the variation i
