Answer: The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.

healthful I think! Hope that helped
Answer:
Healthful - A social club organizes a health fair at school.
Unhealthful - A social club organizes a bike race after dinner on a school night.

People would not feel good biking if they just ate right before the race. The race also might go long so people wouldn't get a good amount of sleep to be prepared for school the next day.
Define A Gamma Ray .....---_---__☘️
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.

In 3-4 sentences, briefly summarize how our solar system formed.
Answer:
Explanation:
Our solar system is formed by a dust storm, which created the planets. This info is grabbed by NASA, and people believe this is how the Solar System is formed. The sun is formed like this too.
Answer:
Well a lot of people believes in evolution. But in fact evolution is actually clearly impossible because how can dead which is Non-Living bacteria and dirt make something alive like living. And anyway there's a lot of thing's in nature that shows there is a creator. Like how does bees know when there honey comb is to warm to start fanning there wings to cool the honey comb down? And like human beings for example we didn't generate from aps. Yes there smart like us and sorta human like but the way our bodies are designed is wayyyyy to complicated. For example our brain its a computer we dont shut it on and off it's always running constantly and we dont have to worry about turning our brain on or off. I know this wasent what u have asked but i made me think about it and also someone created the universe because the whole universe hangs on nothing but they stay aligned. So this shows that there is a creator though.
Explanation:
Hope this helps you in some way of form. :)

A sports car starts at rest at the starting marker then picks up speed, then passes the finish marker in 4.1 seconds. The markers are separated by 120 meters. What is the car's speed at the second marker?
Answer:
S=29.298m/s
Explanation:
Use S=d/t
So, S=120m/4.1s= 29.298m/s

how do you find the kinetic energy of an object?
Answer:
KE = 1/2 * m * [tex]v^{2}[/tex]
Explanation:
use the formula:
KE = 1/2 * m * [tex]v^{2}[/tex]
KE = kinetic energy in joules (J)
m = mass in kg
v = velocity in m/s
Answer:
KE=1/2mv^2
Explanation:
I hope this helps it's just the formula.
KE=1/2×mass×velocity^2

What is the name of the process whose main purpose is to use energy released and stored during the Krebs cycle to form ATP? 1. The Krebs cycle 2. Electron transport chain 3. Photosynthesis 4. Glycolysis
Answer:
4. Glycolysis
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Hence, the name of the process whose main purpose is to use energy released and stored during the Krebs cycle to form ATP is glycolysis.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
Answer:
the Krebs cycle
Mario and Patience are making cookies. They are ready to drop balls of dough on baking sheets. They have baking sheets made of treated glass, aluminum, stainless steel, and copper. The specific heats of these substances are:
Treated glass = 0.75 J/g • °C
Aluminum = 0.90 J/g • °C
Stainless steel = 0.50 J/g • °C
Copper = 0.39 J/g • °C
Based on the specific heat values, which sheet is going to warm up the quickest, and, therefore, bake the cookies the fastest?

What is the momentum of a 110kg fullback running at 860 m/s?*
Answer:
94600kgm/s
Explanation:
Linear momentum of a body can be calculated using the formula;
P = mv
Where;
P = linear momentum (Kgm/s)
m = mass of body (kg)
v = speed of the moving body (m/s)
According to the provided information in the question, m = 110kg, v = 860m/s
P = 110 × 860
P = 94600kgm/s

What types of changes in motion cause acceleration?
Answer:
Change in velocity and direction over a specific period of time.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate the acceleration of an object.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
[tex]a = \frac{v - u}{t}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Hence, the types of changes in motion that cause acceleration is a change in velocity and direction over a specific period of time.
4. How much force is required to accelerate a 5 kg mass at 2 m/s??
Answer:
Clearly, F1>F2, i.e., greater force would be required in accelerating a 2kg mass at 5m/s2.

1. Why do you think it is important for people to know when the tides will be high and/or low?
Many reasons. Here are a couple:
1.) Water depth for the draft of incoming ships/vessels so they do not run aground.
2.) Distance between sea level and bottom of structures such as bridges for vessels passing underneath.
