explain how the composition of a star that will form a billon years in the future will differ the composition of our sun.
Answer:
Explanation:
Basically the star slowly burns its hydrogen into Helium. Depending on the mass, the star will have a turbulent core where the Helium will be fully mixed or a radiative core where the helium will settle at the centre (remember it's heavier than Hydrogen). The second case is what happens in the Sun.

1. A net force of 15 N is applied to a cart with a mass of 2.1 kg.
a. What is the acceleration of the cart?
b. How long will it take the cart to travel 2.8 m, starting from rest?
Answer:
acceleration=force*mass
a=fm
a=15*2.1
a=31.5
acceleration is 31.5
hope it helps
What does Newton's Second Law state and what are the formulas used?
Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

If you wanted to find an element that
would react similarly to chlorine (CI),
where would you look and why?
Answer: Fluorine (F) and chlorine (Cl) are two good choices. See reasoning below.
Explanation: Mendeleev arranged the elements in the periodic table in a manner that each group, or vertical column, contained elements that exhibited similar chemical properities. He even reserved spaces for undiscovered elements when none of the known elements had properties similar to those above or below the known elements in a group. An interesting event illustrates this property. In December 2010, NASA announced an important new discovery that was to be broadcast on live TV, creating much speculation (e.g., UFO's are real and we'll see the aliens sequestered at Roswell!!! I knew it.).
The actual announcement:
"Dec. 2, 2010: NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California's Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components."
A look at the periodic table shows arsenic just below phosphorus, in the same group. This was an unexpected find, but it might have been predicted with an understanding of how the elements are organized.
Side note: look how close silicon is to carbon. Can there be a life form whose being is made up of silicon instead of carbon? Sure . . . why not? Maybe not on Earth, but . . . wait . . . did that marble statue just wink?

Answer:
a device for repeatedly generating static electricity by induction.
Explanation:
write 9.423 x 10^-9 in expanded form
Answer:
Very large and very small numbers written in standard form take up a large amount of space. They are hard to read and understand and are difficult to use in mathematics. One way to write a very large or very small number is to use a different form of notation. Converting to a workable number is done using scientific or engineering notation.
Explanation:
A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of 11 m/s in a time of 28 s. The combined mass of the boat and trailer is 410 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car
The tension on the hitch that connects the trailer to the car is 160 N.
From the information provided;
Initial velocity = 0 m/s (the car started from rest)
Final velocity = 11 m/s
Time taken = 28 s
From the formula;
a = v - u/t
a = 11 - 0/28 = 0.39 ms-2
The force that acts on the trailer = tension in the hitch that connects the trailer to the car
Force = mass × acceleration
Force = 410 kg × 0.39 ms-2
Force = 160 N

Allison drove 150 miles for 2.5 hours.
Benjamin drove for 2.73 hours and traveled 175 miles.
• Lily drove 160 miles for 2.58 hours.
• George drove for 2.46 hours and traveled 155 miles.
Which person drove at the fastest constant speed?
The formula for calculating speed: Speed = Distance/Time
Answer:
Benjamin was fastest
Explanation:
Allison- 150/2.5= 60mph
Benjamin- 175/2.73= 64.1
Lily- 160/2.58= 62.01
George- 155/2.46= 63.008

Question 8 of 35
A car has a mass of 1000 kg and is travelling at a speed of 26 m/s. Calculate the kinetic energy of the
car. Use the word equation below to help you.
kinetic energy = 0.5 x mass x (speed)?
Answer:
338,000 JExplanation:
The kinetic energy of an object can be found by using the formula
[tex]k = \frac{1}{2} m {v}^{2} \\[/tex]
m is the mass
v is the velocity
From the question we have
[tex]k = \frac{1}{2} \times 1000 \times {26}^{2} \\ = 500 \times 676 \\ = 338000[/tex]
We have the final answer as
338,000 JHope this helps you
The precision of a balance is ±0.02 g. The accepted value for a measurement is 26.86 g. Which measurement is in the accepted range?
26.02 g
26.82 g
26.87 g
26.90 g
Explanation:
The precision of a balance is ±0.02 g.
The accepted value for a measurement is 26.86 g.
The accepted range is: =[26.86-0.02, 26.86+0.02] = [26.84, 26.88]So,26.87 g is correct
