Below is an attachment containing the solution.
Answer:
Surface area of the dog is changes from A to 3A
Explanation:
It is given that surface area of dog is increased by factor 3 in a period of 4 year
We have to find the change in dog's relative surface area in the given time period
Let initially the surface area is A
As the surface area is increased by a factor of 3
So surface area after 4 year = 3×A = 3A
So surface area of the dog is changes from A to 3A
Answer:
500÷25=20
so 20 coulombs per second

The characteristics of the shadow allow to find the result for the change of the sun's rays are:
-
As the person advances from the equator to the poles the rays are less perpendicular, which is reflected in a longer shadow.
The shade is a space where the sun's rays do not reach.
When the person is at the equator, his shadow is very small, indicating that the rays are falling vertically.
As the person increases his latitude, a shadow begins to appear every larger shade, due to two processes:
-
The earth is spherical, therefore there is an angle between the normal to the earth's surface and the sun's ray , which is why there is a region where the sun does not reach.
- The Earth has an inclination with respect to the sun and this inclination changes in the course of the year.
When the person is just over the north pole, the shadow should be infinite, which indicates that the person is parallel to the sun's rays. In reality, due to the inclination of the earth, the shadow is very long, but finite.
In conclusion using the characteristics of the shadow we can find the result for the change of the sun's rays are:
-
As the person advances the sun's rays are less perpendicular, which is reflected in a longer shadow.

<span>If I will be the judge, the passenger will not be injured by
suitcase came from the front of the bus because when the driver slammed the
break the inertia of the force must be moving forward. It impossible for a suit
case to move backwards, maybe the passenger was the one flying forward and hit
something </span>
