Explanation:
It is given that total distance is 3.65 m and times is 33.1 s. Therefore, calculate the average speed as follows.
Average speed =
=
= 0.11 m/s
Also, we know that
Average velocity =
Where, displacement means that how far final point is from the initial point, here, that is 0.0463 m.
Hence, calculate the average velocity as follows.
Average velocity =
= 0.0014 m/s
Thus, we can conclude that gnat's average speed is 0.11 m/s and magnitude of the gnat's average velocity is 0.0014 m/s.
Answer:
1. about 1.5 AU
2. about 5 AU
3. about 8 light-years
4. about 100,000 light-years
5. less than 0.01 AU
Explanation:
a. Mars is about 1.5 AU from the Sun.
b. Jupiter is about 5 AU from the Sun.
c. The star Sirius is about 8 light-years from the Sun.
d. The diameter of the Milky Way Galaxy is about 100,000 light-years.
e. The distance from Earth to the Moon is less than 0.01 AU.
Note: AU is an acronym for Astronomical Unit and it is a standard unit by astronomers to illustrate the distance between the planetary bodies found in the solar system.
Answer:
The acceleration will also double
Explanation:
F = m*a
a = F/m
plugging in sample numbers to prove
a= 100/4 = 25
a = 200/4 = 50
Answer:
The formula for calculating Density is:
= Mass / Volume
From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.
If mass however was decreasing, density would have to decrease as well.
For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.
Density of 5kg brick = 5 / 5 = 1 kg/m³
Density of 10kg brick = 10 / 5 = 2kg / m³
Density of 15kg brick = 15 / 5 = 3 kg /m³
<em>Notice how density increases as mass increases and decreases when mass decreases. </em>
