A group of students is making paper airplanes. They think that the kind of paper and the design of the airplane may affect how for each paper airplane fles. The students first test if the kind of paper affects how far the
airplane fies. They make
several otrplanes out of different kinds of paper, using
the same design Why is it important that all the airplanes have the same design?
Help please !!
Answer:
The reason why it is important that all the airplanes have the same design is that the students first test is an experiment to determine the effect of the paper kind on the distance the airplane flies
The first experiment, therefore measures the effect of the independent variable, which is the kind of paper on the dependent variable, which is how far the paper flies
The constant or the factor held constant in the experiment is the design of the airplane, so as to ensure that changes in the distance flown by the airplane are due to the changes in the kind of paper alone
Explanation:
What is cartilage?
7 points
the connective tissue that attaches muscles to bones
the connective tissue that's found between bones
the connective tissue found inside of bones
"The connective tissue that's found between bones."
An example would be between the vertabrae in the spine.
Like the other (inappropriate) answer said, a ligament is what attches muscles and bones.
Also, the tissue inside of bones is bone marrow.
If you know that, you can take out those two options (Option 1 and 3)
Answer:
firm, whitish, flexible connective tissue found in various forms in the larynx and respiratory tract, in structures such as the external ear, and in the articulating surfaces of joints. It is more widespread in the infant skeleton, being replaced by bone during growth
A box with a weight of 100 N is at rest. It is then pulled by a 50 N horizontal
force. What is the mass of the box?
If the box weighs 100N on Earth, then its mass is 10.2 kg. A pulling force has nothing to do with it.

what is displacement and distance
Answer:
Displacement is how far you are between your initial and finishing position.
Distance is how far you went.
Explanation:
For example, using a baseball field... if the sides are each 100 m..
A batter runs to third base... what is his displacement and distance?
Since the batter ran to 3rd base, it means he ran 300 m to get to 3rd base but his displacement is 100 m becuase that's how far they are from home plate. (which was their starting position)
So the answer to my example above would be:
Distance: 300 m
Displacement: 100 m

If white light is a mixture of all the primary colours of light, what is black?
Answer:
The primary colors of light are red, green, and blue. If you subtract these from white you get cyan, magenta, and yellow. ... Mixing these three primary colors generates black. As you mix colors, they tend to get darker, ending up as black.
What is the weight of a 500g ball? (gravity is 9.8 m/s)
Answer:
4,900
Explanation:
you find the weight by multiplying the ball in grams to the gravity
The weight or force due to gravity of a 500 g ball is 4.9 N.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in the question a 500 g ball,
Weight = mass.gravity
Weight = .5*9.8
Weight = 4.9 N
The weight or force due to gravity of a 500 g ball is 4.9 N.

How to get the radius from the circumference?
Answer:
The equation Pi = c/2r means that Pi (r) = c/2, so r = c / (2 Pi). The radius of a circle is therefore equal to c / (2 Pi), where c is the circumference of the circle.
Explanation:

Explanation:
If we drop two iron balls, one ball is bigger than another one, from
same height which will fall first to ground? Explain why.
Answer:
The bigger one. Ignoring air resistance, they will fall at the same speed, but the bigger one will hit first because it sticks out lower.
Explanation:
A grapefruit falls from a tree and hits the ground 0.72 s later.
How far did the grapefruit drop?
What was its speed when it hit the ground?
Answer:
The grapefruit dropped 2.54 m and hit the ground at 7.06 m/s
Explanation:
Free Fall Motion
A free-falling object falls under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not encounter air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is [tex]g = 9.8 m/s^2.[/tex]
The final velocity of a free-falling object after a time t is given by:
vf=g.t
The distance traveled by a dropped object is:
[tex]\displaystyle y=\frac{gt^2}{2}[/tex]
Given a grapefruit free falls from a tree and hits the ground t=0.72 s later, we can calculate the height it fell from:
[tex]\displaystyle y=\frac{9.8\cdot 0.72^2}{2}[/tex]
y = 2.54 m
The final speed is computed below:
[tex]vf=9.8\cdot 0.72[/tex]
vf = 7.06 m/s
The grapefruit dropped 2.54 m and hit the ground at 7.06 m/s
An airplane is flying with velocity of 70km\hr in north east direction .The wind is blowing 30km\hr from north to south.What is the resultant displacement of the aeroplane in 4 h
Answer:
The resultant displacement of the airplane in 4 hours is 212.8 km.
Explanation:
The components of the airplane's velocity and wind's velocity are:
Airplane:
[tex] v_{a_{x}} = v_{a}cos(45) = 70 km/h*cos(45) = 49.50 km/h [/tex]
[tex] v_{a_{y}} = v_{a}sin(45) = 70 km/hsin(45) = 49.50 km/h [/tex]
Wind:
[tex] v_{w_{x}} = 0 [/tex]
[tex] v_{w_{y}} = v_{w} = -30 km/h [/tex]
Now, to know the new velocity of the airplane we to find the result vector:
[tex] v_{x} = v_{a_{x}} + v_{w_{x}} = 49.50 km/h + 0 = 49.50 km/h [/tex]
[tex]v_{y} = v_{a_{y}} + v_{w_{y}} = 49.50 km/h - 30 km/h = 19.50 km/h[/tex]
Now, the magnitude of the new speed of the airplane is:
[tex] v_{a} = \sqrt{v_{x}^{2} + v_{y}^{2}} = \sqrt{(49.50 km/h)^{2} + (19.50 km/h)^{2}} = 53.20 km/h [/tex]
Finally, after 4 hours the resultant displacement of the airplane is:
[tex] x = v*t = 53.20 km/h*4 h = 212.8 km [/tex]
Therefore, the resultant displacement of the airplane in 4 hours is 212.8 km.

PLSSSS HELPPP What effects do mutations have? Check all that apply.
A) could change protein shape
B)never change protein shape
C)might be neutral
D)always change the way a trait is observed
E)might be harmful
F)might be beneficial
Answer:
E, F, A, C
Explanation:
They cannot change the way a trait is observed
Mutations could change protein shape(A), could cause genetic disorders and harm you(E), could actually be beneficial and cause adaptations to your environment(F), or they could be neutral in which no changes are observantly notable(C).
