Term specifically describes small chunks of rocks and debris in space that burn up in Earth’s atmosphere is :
Meteors
Explanation:
- A meteor is a meteoroid or a particle broken off an asteroid or comet orbiting the Sun – that burns up as it enters the Earth's atmosphere, creating the effect of a "shooting star".
- Meteoroids that reach the Earth's surface without disintegrating are called meteorites.
- Due to Earth's escape velocity, the minimum impact velocity is 11 km/s with asteroid impacts averaging around 17 km/s on the Earth. The most probable impact angle is 45 degrees.
- Meteoroids have a pretty big size range. They include any space debris bigger than a molecule and smaller than about 330 feet space debris bigger than this is considered an asteroid.
- But most of the debris the Earth comes in contact with is "dust" shed by comets traveling through the solar system.
- The surface of a meteorite is generally very smooth and featureless, but often has shallow depressions and deep cavities resembling clearly visible thumbprints
- Most iron meteorites, like the example at right, have well-developed regmaglypts all over their surface.

Answer:
n this question, we are asked to find the probability that
R1 is normally distributed with mean 65 and standard deviation 10
R2 is normally distributed with mean 75 and standard deviation 5
Both resistor are connected in series.
We need to find P(R2>R1)
the we can re write as,
P(R2>R1) = P(R2-R1>R1-R1)
P(R2>R1) = P(R2-R1>0)
P(R2>R1) = P(R>0)
Where;
R = R2 - R1
Since both and are independent random variable and normally distributed, we can do the linear combinations of mean and standard deviations.
u = u2-u1
u = 75 - 65 = 10ohm
sd = √sd1² + sd2²
sd = √10²+5²
sd = √100+25 = 11.18ohm
Now we will calculate the z-score, to find P( R>0 )
Z = ( X -u)/sd
the z score of 0 is
z = 0 - 10/11.18
z= - 0.89
Answer:
True. 18-year old teenagers that practice some sport or have a hobby have less references to substance abuse or violence.
Explanation:
When someone practices a certain sport, he/she is occupied with its sport, also, sports encourage responsability, discipline and takes most of the person´s time and energy. People who doesn´t practice sports or have any hobby have more idle time and is always looking for something to take away the boredom. Most of the cases they start doing drugs or start having violent episodes because is what´s more handful and gives them the dopamine that the sport is not giving them (because they don´t practice any).
This is way the display of sports or hobbies involvements is associated with decreased references to risky behavior.
