How are clouds related to water vapor and water droplets?
A.Water vapor in the air condenses to form tiny water droplets, and these water droplets make up clouds.
B.Water vapor in the air makes up clouds, but water vapor does not condense to form tiny water droplets that make up clouds.
C.Water vapor in the air condenses to form tiny water droplets, but the water vapor and water droplets do not make up clouds.
D.Water vapor in the air stays in the air as water vapor. The water vapor does not make up clouds, and it does not condense to form tiny water droplets.

The center of mass changes
Explanation:
The higher the center of mass the more likely things are to topple over but the lower it is the more likely to stay put when all 4 wheels are down .

3. Which of the following is determined by the
force of gravity?
A weight
B momentum
C mass
D distance
Answer:
A) weight is determined by the force of gravity.
Answer:
A weight
Explanation:
The answer is weight. That's why someone would weigh more on a different planet, because the planet would have a higher/lower force of gravity.

What is the equation used to find the image distance? Identify each variable
Answer:i f I understand your question correctly, the formula is as follows:
Note: The sign convention is based on distances which are measured from the lens to the object or image of regard. Distances measured in the same direction the light is moving are positive and distances measured in the opposite direction the light is moving are negative.
The measurements are in meters
The “ambient” index of refraction is assumed to be n=1.00
The inverse of the object distance plus the dioptric power of the lens (convex—positive and concave—negative) equals the inverse of the image distance.
Or 1/Od +Dl =1/Id
Please note, it has been a long time since I thought about teaching this concept to students.
Hope this helps have a awesome day/night❤️✨Explanation:
pls help, i really dw fail :(
Answer:
Using the Newton equation
V²=U² +2as
Given; V=9.2m/s U = 0m/s( because it starts from rest)
S=26.2m.
9.2²=0²+2(26.2)a
a =9.2²/2(26.2)
a=84.6/52.4
a=1.60m/s²

How many seconds will it take for a the International Space Station to travel 450 km at a rate of 100 m/s?
Time = (distance) / (speed)
Time = (450 km) / (100 m/s)
Time = (450,000 m) / (100 m/s)
Time = 4500 seconds (that's 75 minutes)
Note:
This is about HALF the speed of the passenger jet you fly in when you go to visit Grandma for Christmas.
If the International Space Station flew at this speed, it would immediately go ker-PLUNK into the ocean.
The speed of the International Space Station in its orbit is more like 3,100 m/s, not 100 m/s.

aight here's the question:
Homeboy Joe is running at 6.65 m/s while Homegirl Jill is running at -1.10 m/s. Home boy Joe and Homegirl Jill hit each other. Homeboy Joe not wanting to be a stage 5 clinger. he makes sure he doesn't hold onto Homegirl Jill after they collide. If Homeboy Joe's mass is 99.5 kg and Homegirl Jill's mass is 68.8 kg. what is Homegir Jill's velocity after they hit if Homeboy Joe's velocity is 2.35?
***Round to the nearest hundredth***
Correct Answer: 5.12
I can't do PEMDAS to save my life can someone show me the correct way to solve with work?
Answer:
[tex]5.12\:\text{m/s}[/tex]
Explanation:
From the conservation of momentum, the total momentum of the system before and after the collision must be the same. Therefore, let the momentum of Homeboy Joe be [tex]p_b[/tex] and let the mass of Homegirl Jill be [tex]p_j[/tex]. We can write the following equation:
[tex]p_{bi}+p_{ji}=p_{bf}+p_{jf}[/tex], where subscripts [tex]i[/tex] and [tex]f[/tex] represent initial and final momentum respectively.
The momentum of an object is given by [tex]p=mv[/tex].
Therefore, we have:
[tex]m_{b}v_{bi}+m_{j}v_{ji}=m_{b}v_{bf}+m_{b}v_{jf}[/tex] (some messy subscripts but refer to the values being plugged in you're confused what corresponds with what).
Plugging in values, we have:
[tex]99.5\cdot 6.65 + 68.8\cdot (-1.10)=99.5\cdot 2.35+ 68.8\cdot v_{jf}[/tex].
Solving, we get:
[tex]v_{jf}=\frac{99.5\cdot 6.65+68.8\cdot (-1.10)-99.5\cdot2.35}{68.8},\\v_{jf}=5.11875,\\v_{jf}\approx \boxed{5.12\:\text{m/s}}[/tex].
It's important to note that velocity is vector quantity, so the negative velocity assigned to Jill simply implies she is moving at [tex]1.10\:\text{m/s}[/tex] in the opposite of Joe's direction. After the collision, she is now moving [tex]5.12\:\text{m/s}[/tex] in the same direction that Joe was initially moving, due to Joe's relatively large mass and initial velocity.

A t-shirt cannon is fired into a crowd at a baseball game. The t-shirt with mass 0.17kg is fired, and the launcher (2.7kg) recoils at 1.7 m/s. Calculate the launch velocity of the t-shirt. Answer to 2 decimals
Answer:
Exactly 27 m/s
Explanation:
P=mv
P(cannon)=2.7*1.7
P(cannon)=4.59 kg*m/s
P(cannon)=P(tshirt)
4.59=0.17*v
v=27 m/s

Do all force interactions cause a noticeable change in motion? Explain your thinking?
!THANK YOU!
Answer:
No. If you apply a force in a chair, for example, you only will be able to move the chair if you beat the static frictional force. So, with that example, we can see that is not any type of force that can produce movement. The only force that produces movement is a result force which is non-zero.
Why is the Greenland ice sheet so important to understanding earths past climate?
Answer:
The ice sheet as a record of past climates
Scientists have, using those ice cores, obtained information on (proxies for) temperature, ocean volume, precipitation, chemistry and gas composition of the lower atmosphere, volcanic eruptions, solar variability, sea-surface productivity, desert extent and forest fires.
Answer:
The Greenland ice sheet is the last remaining ice sheet from the most recent ice age. Therefore, it can tell scientists about the climate conditions of that period.

Provide two reasons why is bronze still used in the manufacture of bells?
(NOVA ASSIGNMENT)
Answer:
Bell makers still use bronze because it has desirable properties, such as hardness and sound quality. The atomic structure of a pure metal is orderly and allows electrons to flow freely through the material. In bronze, the addition of tin to copper restricts the movement of the copper atoms.
