Two kids are swinging on a swing set. If one kid is larger than the other, how would it affect their kinetic and potential energy? If they both jumped off the swing, who would fly farther? Why?
Answer:
Yes it would affect the energy. the one who is smaller would fly
Explanation:
the larger kid is carring all the weight so he would have more energy on his side and the smaller kid would fly bc he lighter and has less energy on his side.
Hope this helps.

Which statement places events during the Space Race in the correct order from the earliest to the most recent?
NASA was established, US satellite Explorer launched, first man walked on the moon, first man orbited the Earth
first man walked on the moon, first man orbited the Earth, NASA was established, US satellite Explorer launched
US satellite Explorer launched, NASA was established, first man orbited the Earth, first man walked on the moon
first man orbited the Earth, first man walked on the moon, US satellite Explorer launched, NASA was established
Answer: The correct statement order from the earliest to the most recent is (US satellite Explorer launched, NASA was established, first man orbited the Earth, first man walked on the moon.)
Explanation:
The United States first Satellite was launched in the date of February 1, 1958. It was given the name 'Explorer 1'. It was a cosmic ray detector which was constructed to measure the radiation environment in earth orbit.
NASA (National Aeronautics and Space Administration) was established in the year 1958 on the first day of October by United States of America. This was created as a response to the Soviet Union over thier first Satellite launch.
First man orbited the earth in the year 1961 on April 12. This was achieved by a Soviet Cosmonaut Yuri Alekseyevich Gagarin.
The first human on the moon is Neil Armstrong through the spacecrafts called Apollo's 11. This event occurred on 20 July 1969

Why can the volume of a sample of plasma change when the substance is moved from one container to another?
A. Plasma is made of charged ions and electrons, so they interact differently in different places.
B. Plasma can have lots of space between its particles, so it naturally expands and compresses.
C. Plasma is made of neutral atoms that can split into separate ions and electrons when placed in a new container.
D. Plasma can change between a rigid shape and a free-moving form, so it will have different volumes in different containers.
The volume of a sample of plasma change when the substance is moved from one container to another because plasma can have lots of space between its particles, so it naturally expands and compresses.
PlasmaPlasma is one of the four states of matter.Plasma refers to a gas that exists as ions or in the ionized state.When sufficient energy has been supplied to the gas, the electrons of the gas have enough energy to escape from their atoms or molecules and the atoms then exist as ions.
Plasma contains ions and electrons that are free to.move around easily.
Matter in the plasma state do not have constant volume or shape, rather it has variable volume and shape. Plasma is the most common form of visible matter in the universe.
Examples of matter that exist in the plasma state include lightning, sparks, the sun, etc
Therefore, the volume of a sample of plasma change when the substance is moved from one container to another because plasma can have lots of space between its particles, so it naturally expands and compresses.

What is longitudinal wave?
0.
Define transverse wave.
Longitudinal waves are those waves which move in the same direction as of the particle of the medium. That means, The Particles of the medium move forward and backward just like the Wave move forward so they propagate in the same direction.
Example:The Sound wave is the example of the longitudinal wave as it propagates in the same direction as the particle do.
_____________________________________Transverse Wave:Transverse wave are those waves which propagate in the perpendicular direction as of the particle of the medium. That means, The particle moves up and down but the wave propagate in forward direction. So they dont move in similar direction but perpendicular.
Example:Water wave is the perfect example of the transverse wave as you can see that water particles form crest(Up the midline) and trough(down the midline) i.e. upward and downward movement but the water actually moves forward in direction.

B. Identifying the types of data to be gathered
Explanation:
Identifying the types of data to be gathered is one of the part of designing a set of experimental procedure.
An experimental procedure is a methodical process that must be followed in order to attain the goal of the experiment.
As with most experiments, data is collected for further analysis and interpretation. The choice of way of collecting data and the type of data to be collected is very important when designing an experiment.50 POINTS!!!!!!!!!!

A projectile is launched with an initial velocity of (40 m/s), at an angle of (30°) above
horizontal. What is the maximum height (ymax) reached by the projectile?
(Use g=10 m/s2).
Answer:
330.5 m
Explanation:
In this case, the object is launched horizontally at 30° with an initial velocity of 40 m/s .
The maximum height will be calculated as;
[tex]h=\frac{v^2_isin^2\alpha }{2g}[/tex]
where ∝ is the angle of launch = 30°
vi= initial launch velocity = 40 m/s
g= 10 m/s²
h= 40²*sin²40° / 2*10
h={1600*0.4132 }/ 20
h= 661.1/2 = 330.5 m

A rubber ball thrown at a speed of 5 m/s hit a flat wall and
returned to the thrower at a speed of 5 m/s. Which
statement correctly describes the momentum of the rubber
ball?
Answer:
See the explanion below
Explanation:
Linear momentum is defined as the product of mass by velocity and can be calculated by the following equation.
[tex]P =m*v[/tex]
where:
P = momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
When the ball hits the wall it receives a force for a very short time, this time and force value is known as momentum and can be calculated by the following expression.
[tex]-(m_{1}*v_{1}) + (F*t)=(m_{1}*v_{2})[/tex]
where:
m₁ = mass of the ball [kg]
v₁ = 5 [m/s]
v₂ = 5 [m/s]
v₁ = v₂
[tex]F*t = Imp[/tex]
[tex]Imp = (m_{1}*v_{1})+ (m_{1}*v_{2})\\Imp = 2*m*v_{1}[/tex]
It can be said that the impulse is equal to 2 times the speed of throwing by the mass.

A ball of mass of 0.5kg is dropped from a height of 2m.
Assuming that all of the GPE is transferred to KE, what
will be the velocity of the ball when it hits the ground?
Answer:
6.3m/s
Explanation:
Given parameters:
Mass of the ball = 0.5kg
Height = 2m
Unknown:
Velocity when the ball hits the ground = ?
Solution:
Since the potential energy is transformed into kinetic energy;
P.E = K.E
mgh = [tex]\frac{1}{2}[/tex] m v²
cancelling m;
gh = [tex]\frac{1}{2}[/tex] v²
v² = 2gh
v = √2gh
Insert the parameters and solve;
v = √2gh = √ 2 x 9.8 x 2 = 6.3m/s
A 12 volt battery is connected to two resistors in series. The first resistor has a resitance value of 5 Ohms and the current through the circuit is 1.5 Amps. What is the value of the second resistor?
a
9 Ohms
b
1.5 Ohms
c
5 Ohms
d
3 Ohms
Answer:
D) 3 ohms
Explanation:
According to one law
V = IR
Where V = voltage or potential difference
I =current
R =resistance
Making R the subject
R= V/I
R= 12/1.5
R=8 ohms
Sum of resistance of resistors in series equals the total resistance
R(total) = R1+ R2
8 =5+ R2
8-5=R2
3=R2
