Answer to Problem 1CQ

Due to the inclination and orientation of the axis of the earth, the intensity of sunlight on a particular location changes as the earth rotates. This causes a variation in the number of daylight hours.

Explanation of Solution

The axis of the earth is tilted and always points towards the North Star. As a result the orientation of the axis of the earth changes throughout the year as it revolves around the sun. At some instant the axis points towards the sun and at the other instance it points away from the sun.

As the orientation of the earth’s axis changes throughout the year, the distribution of sunlight also changes across different latitude. This causes a seasonal variation in the number of hours of daylight. The variation in intensity is due to the angle at which the sun’s rays hit the earth and it changes throughout the year.

Answer to Problem 1CQ

Due to the inclination and orientation of the axis of the earth the intensity of sunlight on a particular location changes as earth rotates. This causes variation in seasons throughout the year.

Explanation of Solution

The axis of the earth is tilted and always points towards the North Star. As a result the orientation of the axis of the earth changes throughout the year as it revolves around the sun. At some instant, the northern hemisphere is towards the sun and at the other instance the southern hemisphere is away from the sun.

Seasons change occurs throughout the year due to the variation of sunlight falling on the earth. The hemisphere close to the sun experiences winter while the other experiences summer and vice versa.

The following figure shows the position of the earth throughout a year.

Shrinking Loop. A circular loop of flexible iron wire has an initial circumference of 161 cm , but its circumference is decreasing at a constant rate of 15.0 cm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 1.00 T , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop. Find the magnitude of the emf E induced in the loop after exactly time 9.00 s has passed since the circumference of the loop started to decrease. Find the direction of the induced current in the loop as viewed looking along the direction of the magnetic field. Please explain all steps
Make up an application physics principle problem that provides three (3) significant equations based on the concepts of capacitors and ohm's law.
A straight horizontal garden hose 38.0 m long with an interior diameter of 1.50 cm is used to deliver 20oC water at the rate of 0.590 liters/s. Assuming that Poiseuille's Law applies, estimate the pressure drop (in Pa) from one end of the hose to the other.
