Given parameters:
Distance = 5km
Time taken = 45 minutes
Unknown:
Speed = ?
Solution:
Speed is a physical quantity.
It is given as;
Speed = [tex]\frac{distance}{time}[/tex]
Since the unknown is speed;
convert the time given to hours;
60min = 1hr
45min = [tex]\frac{45}{60}[/tex] = [tex]\frac{3}{4}hr[/tex]
So, speed = [tex]\frac{5}{\frac{3}{4} }[/tex] = 5 x [tex]\frac{4}{3}[/tex]
= [tex]\frac{20}{3}[/tex]km/hr

Answer:well... i don't really know how i remember, but here is a list:
1st is Mercury, the smallest planet.
2nd is Venus, which is not exactly earth's twin, even though many people say so.
3rd is earth, which is where we live on!
4th is mars, which is about 1/3 the size of earth.
Then, we go to the gas giants, which are all gas.(the others were rocky, like earth.
5th, which is Jupiter, is the biggest of the planets.
6th is Saturn, which has cool rings.

The Little Dipper is a group of stars. During the night the Little Dipper appears to change positions in the sky. Which of these statements best explains why the Little Dipper appears to change positions in the night sky? * A. Earth rotates on its axis. B. Earth revolves around the stars. C. The Little Dipper moves around the sun. D. The stars in the Little Dipper move in the sky. 2. Which of these changes on Earth would be likely if Earth were farther from the sun? *
Answer:
1. A. Earth rotates on its axis
2. If the earth were closer to the sun, the temperature would be much higher.
Explanation:
As the night passes we can see that there is a certain movement of the stars. Regarding the bear, we can see that it appears in different positions in different perspectives. This happens due to the rotation of the earth in relation to its own axis. The smaller bear is too far from the earth for the proper movement it represents to be perceived, so it is the movement of the earth that provides the displacement sensation of the small bear.
If the earth were closer to the xol, we would see a big change in its temperature. The land would become much hotter, and it may even be impossible to keep bodies of water and living beings on its surface.

**CHALLENGE** Find all of the missing angles - a, b, c, and d.
Answer:
a = 65°
d = 75°
b = 25°
c = 25°
Explanation:
To solve the given problem, we are going to use different angle theorems.
Using these theorems, it would be possible to establish the relationship between the unknown and given angles.
A.
To solve for angle a, we are going to use the concept of angles on a straight line.
The sum of angles on a straight line is 180°
Therefore;
60 + 55 + a = 180
115 + a = 180
a = 180 - 115
a = 65°
B. To solve for angle d, we are going to use the concept of right angles.
Angle in a right angle is 90°;
So:
d + 15 = 90
d = 90-15 = 75°
C. To find angle, b, since we know a, we use angles in a right angle triangle.
Sum of angles in triangle = 180°
a + b + 90 = 180
b = 180 - 90 -a
b = 90 - 65 = 25°
D. Angles b and c are vertically opposite and can be said to be the same.
So b = c
c = 25°

What is Seismometer?A seismometer is a device that detects vibrations in the ground brought on by explosions, volcanic eruptions, and earthquakes. A seismograph is typically made up of them along with a timing device and a recording device.
A seismograph, also known as a seismometer, is a device used to identify and document earthquakes. It typically consists of a mass that is fastened to a fixed base. The base moves during an earthquake but the mass does not. It is common to convert the base's motion with respect to the mass into an electrical voltage.

Answer:
C Is the answer
Explanation:
which location experiences the greatest range in daylight hours throughout the year
a.anchorage, AK
b.Chicago, IL
c. Quito, Equador
d. Melbourne, Australia
Answer:
Anchorage, AK, experiences the greatest range in daylight hours throughout the year.
Explanation:
The daylight patterns throughout the year differ from place to place. The biggest factor is the latitude. The basic rule is that the closer a place is to the Equator the smaller the difference in daylight hours, and the further away it is the greater the range in daylight hours. This is due to Earth's inclination, where the higher latitudes get more affected throughout the year, while the lower latitudes have little to no difference.
Anchorage is the place that is furthest away from the Equator, thus it experiences the most daylight in summer, and the least daylight in winter, making a big difference between the two. Chicago comes in second and Melbourne third, while Quito has the smallest range of daylight because it is right next to the Equator, so the daylight is almost the same all year-round.
