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.

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

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
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.

Extremely slow movement is not easily observed directly. C. Extremely complex movement is not easily observed directly. D. Extremely dangerous movement is not easily observed directly.
Answer: the answer is B. Extremely slow movement is not easily observed directly.
Extremely slow movement is not easily observed directly.
What are Continents?One of Earth's seven major landform divisions is the continent. The continents are Asia, Africa, North America, South America, Antarctica, Europe, and Australia, in order of largest to smallest.
Geographers typically include all the islands connected to a continent when identifying it. For instance, Japan is a country that belongs to Asia. Normally, all of the Caribbean Sea islands and Greenland are regarded as being in North America.
The combined area of the continents is roughly 148 million square kilometers (57 million square miles). Most of Earth's land surface, but not all of it, is made up of continents. Islands that are not physically a part of continents make up a minuscule amount of the overall land area.
Therefore, Extremely slow movement is not easily observed directly.

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

The average mass of a car in the US is 1.440 x 10^6 g. Express this mass in kg.
Answer:
Average mass of acar in the US (in kg) = 1440 kg
Explanation:
Average mass of a car in the US (in g) = 1.440 × 10⁶ g
Mass in kg:
[tex] \rm 1 \: g = {10}^{ - 3} \: kg \\ \\ \rm 1.440 \times 10^6 \ g = 1.440 \times 10^6 \times {10}^{ - 3} \ kg \\ \\ \rm = 1.440 \times 10^{6 - 3} \ kg \\ \\ \rm = 1.440 \times 10^3 \ kg \\ \\ \rm = 1.440 \times 1000 \ kg \\ \\ \rm = 1440 \ kg[/tex]
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.

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
A rock is dropped (from rest) off a bridge over the Merrimack River. The falling rock
accelerates at 10 m/s2 downward. If it takes 2.5 seconds before a splash is heard,
approximately how high is the bridge?
Answer:
31.25 meters or ~31 meters approximately
Explanation:
Let's see which of the 5 variables we are given since this is a constant acceleration problem.
[tex]v_i \ \ \ \ \ \ t \\ v_f \ \ \ \ \ \triangle x \\ a[/tex]We want to find the height of the bridge, aka the vertical displacement of the rock. Let's set the upwards direction to be positive and the downwards direction to be negative.
We are told that the acceleration is 10 m/s² downward, so we have a = -10 m/s².
We are also told that the time it takes the rock to hit the water is 2.5 seconds. Time is the same regardless of the x- or y- direction, so we can say that t = 2.5 seconds.
Now, we aren't told this directly, but we can figure out that the velocity in the y-direction is 0 m/s, since the rock is dropped from rest off the bridge. Therefore, [tex]v_i=0 \frac{m}{s}[/tex].
We want to find the vertical displacement, the height of the bridge, so we can say that [tex]\triangle x= \ ?[/tex]
We have 4 out of 5 variables:
[tex]v_i,\ a, \ t, \ \triangle x[/tex]Look through the constant acceleration equations to see which equation has all 4 of these variables. You should come up with this one (no final velocity):
[tex]x_f=x_i+v_it+\frac{1}{2}at^2[/tex]Subtract [tex]x_i[/tex] from both sides of the equation to get:
[tex]\triangle x=v_it+\frac{1}{2}at^2[/tex]Substitute in our known variables and solve for delta x.
[tex]\triangle x=(0\frac{m}{s})(2.5s) + \frac{1}{2} (-10\frac{m}{s^2})(2.5s)^2[/tex]0 m/s multiplied by 2.5 s is 0, so we have:
[tex]\triangle x =\frac{1}{2} (-10)(2.5)^2[/tex]Evaluate the exponent first and multiply the terms together.
[tex]\triangle x =(-5)(6.25)[/tex] [tex]\triangle x =-31.25[/tex]The vertical displacement is -31.25 meters from the rock's starting position, so we can say that the height of the bridge is 31.25 meters, which is approximately 31 meters tall.
Answer:
31 meters

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.
