2)What are the levels of Scientific Knowledge from the Lowest to the Highest?
3)What are the 5 steps of the scientific method ? Explain what EACH one is.

5)Why do we call the metric system the “SI” system in Science?
6)The Metric System is based on the meter and what other thing? Why does that make metric easier to understand?
7)What are 3 base units we use for Length, Volume, and Mass? How do you represent them with initials? Which one is capitalized?
8)
25 km = cm

358mm = m
76kg = g
20L = ml
9)Metric is based on universal constants (things you can measure) rather than examples (a person’s hand or food or a grain of rice). Why is this a good thing? Why is it important for Science too?
10)What did these folks do wrong?
Belinda and Suzy are working with Bob in the lab today. They decide to play a trick on him. They tell him that even though it isn’t written down, the teacher said that when they are done with today’s experiment, they should drink the solution because it tastes just like Dr.Pepper. Bob believes them (Belinda is very cute, after all) and makes a moveto pick up his still steaming beaker. Name at least two things that these three should improve on.

Based on Newton’s third law of motion, will a tennis ball go farther if it hits a tennis racquet that is still or one that is in motion?
OPTIONS:
A.
One that is still because it will absorb all of the force of the ball.
B.
One that is still because that will have a greater impact on the trajectory.
C.
One that is in motion because both the ball and the racquet will contribute momentum.
D.
One that is in motion because the racquet’s force will cancel the ball’s force out.
Answer:
c
Explanation:
because if a tennis ball hit a tennis racket still it would not go anywhere. with the tennis ball hitting the moving racket it will go further
One that is in motion because both the ball and the racquet will contribute momentum.
Thus, option (c) is correct.
Newton's third law of motion states that for every action, there is an equal and opposite reaction.
When the tennis ball hits a tennis racquet in motion, both the ball and the racquet will exert forces on each other in opposite directions.
This interaction will result in a transfer of momentum from the racquet to the ball and vice versa, potentially giving the ball a greater momentum and therefore potentially causing it to go farther.
Thus, option (c) is correct.

The table contains the planets in our solar system in order of their average distance from the Sun and their corresponding diameters. The first step in creating a model of the solar system is to scale these large diameters into smaller, more manageable numbers. Eventually, we’ll represent these numbers using circles drawn on paper. MercuryVenusEarthMarsJupiterSaturnUranusNeptune Diameter (km)487912,10412,7566792142,984120,53651,11849,528 Scaled Diameter (cm) 3.51.9 The ratio between Earth’s actual diameter and its scaled diameter can be used to find the scaled diameter of the other planets. Earth’s diameter of 12,756 kilometers is scaled to 3.5 centimeters as shown in the table. Now let’s find the scaled diameter of Mars as an example. Using the calculations shown, Mars’s diameter of 6,792 would be scaled to 1.9 centimeters. d × 12,756 = 6,792 × 3.5 d = 1.9 cm Use this same process to complete the table with the scaled diameters of the other planets. Round each answer to the tenths place. If you need additional math help, visit the Proportions section of the Math Review.
The scaled diameters of the missing planets are listed below:
Mercury 1.4 cm
Venus 3.3 cm
Mars 1.9 cm
Jupiter 39.2 cm
Saturn 33.1 cm
Uranus 14.0 cm
Neptune 13.6 cm
How to determine the scaled diameters of a planet
In this question we must use conversion factor to calculate the scaled diameters by means of the following direct relationship:
d = k · D (1)
Where:
D - Real diameter, in kilometers.d - Scaled diameter, in centimeters.k - Conversion factor, in centimeters per kilometer.The conversion factor is found by using the real and scaled diameter of the Earth:
k = 3.5 cm/12,756 km
k = 7/25512 cm/km
Then, we determine the scaled diameters of the rest of planets:
Mercury 1.4 cm
Venus 3.3 cm
Mars 1.9 cm
Jupiter 39.2 cm
Saturn 33.1 cm
Uranus 14.0 cm
Neptune 13.6 cm
Remark
The statement reports a table with numerous mistakes, the correct table is shown below:
Planet Diameter (km) Scaled Diameter (cm)
Mercury 4,879
Venus 12,104
Earth 12,756 3.5
Mars 6,792
Jupiter 142,984
Saturn 120,536

Why is the temperature of a normal healthy old man is less than that of a normal healthy young man?
Answer:
Normal body temperature does not change much with aging. But as you get older, it becomes harder for your body to control its temperature. A decrease in the amount of fat below the skin makes it harder to stay warm.

an object is moving forward with a constant velocity. which statement about this object must be true?
Answer:
• Its acceleration is zero
Explanation:
from definition of acceleration:
[tex]{ \rm{acceleration = \frac{change \: in \: velocity}{time} }} \\ \\ { \rm{acceleration = \frac{ \delta \: (velocity)}{time} }}[/tex]
• since velocity is constant, change in velocity is zero
[tex]{ \boxed{ \rm{ \delta \: (velocity) = 0}}}[/tex]
• therefore:

a spiral galaxy can be described as what type of shape
Spiral galaxies are also known as twisted collection of stars and gas that have often beautiful shape and are made up of hot young stars.
There are various types of galaxies based on their shapes such as spiral, elliptical, oval etc. The spiral shaped galaxies are called spiral galaxies.
What are galaxies?Galaxies are a groups of stars, dust and dark matter which are connected by the gravitational force. There are billions of galaxies in the universe and each containing trillions of stars. The galaxy nearest to earth is milky way.
The spiral structure that radiate from the galactic disc's core and give spiral galaxies their name. The central bulge, at the ends of which the spiral arms originate, is seen to have an additional component in the shape of a bar-like structure in about two-thirds of all spirals.
Nearly the course of the universe's history, the ratio of barred spirals to barless spirals has probably varied, going from only 10% approximately 8 billion years ago to about a quarter 2.5 billion years ago to over two-thirds of the galaxies in the observable universe at the present.

11. A roller coaster car is moving slowly up a long ramp to the very top of the roller coaster. It goes over the top and starts down a steep slope and it picks up speed rapidly as it rolls down an almost vertical slope. Four seconds later, at the bottom of the steep slope, its velocity is 28 m/s. The average acceleration during those 4 seconds was 6 m/s2 . What was the initial velocity of the roller coaster car as it started down the slope?
Answer:
a = (v2 - v1) / t
a t = v2 - v1
v1 = v2 - a t
v1 = 28 m/s - 6 m/s^2 * 4 s = 4 m/s

What is the initial velocity of a moose who
accelerates uniformly at 1.5 m/s/s for 5 seconds and
finishes with a velocity of 7 m/s?
Answer:
- 0.5 m/s
Explanation:
(1) Acceleration = change in velocity / time
(2) Change in velocity = (Final velocity - Initial velocity)
We know:
acceleration = 1.5 m/s/s
time = 5 seconds
final velocity = 7 m/s
x = initial velocity)
1.5 = ( 7 - x ) / 5
1.5 x 5 = ( 7 - x )
7.5 = 7 - x
x = -0.5 m/s
You can check the answer by plugging in the values to equation (1).
