Acceleration= change
-----------
Time
The change in velocity is 4 m/s b/c 7-3=4.
The time taken is 5 s b/c 10-5 = 5.
So its 4/5 which is
0.8 m/s^2.
You're welcome.
Meteors: A small body of matter from outer space that enters the earth's atmosphere, becoming incandescent as a result of friction and appearing as a steak of light.
Meteorites: A meteor that survives it passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel.<span />
Answer:

Answer:
Q = 2.60 • J
Explanation:
Our specific heat capacity equation is:
Q = mC∆T
Q is the energy in joules.
m is the mass of the substance.
∆T is the temperature chance.
Let's plug in what we know.
- We have 76.0 g of octane
- The specific heat capacity of octane is 2.22 J/(g•K)
- The temperature increases from 10.6º to 26.0º (a 15.4º increase)
Q = 76.0(2.22)(15.4)
Multiply.
Q = 2598.288
We want three significant figures.
Q = 2.60 •
or
Q = 2590 J
Hope this helps!
