Answer:
See the answer below
Explanation:
Newton's third law states that for every action, there will always be an opposing reaction of equal magnitude to the action.
<em>Hence, the wall will exert an equal opposing force to the head and the roommate will feel this opposing force as pains and/or headache. </em>
Answer:
The distance traveled is 44.45 m
Solution:
As per the question:
Average speed, 
Time, t = 1.6 s
Now, convert the average speed into m/s:
1 km = 1000 m
1 h = 
To calculate the distance traveled:
Now,
We know that:
Speed, 
Thus
Explanation:
density = mass/ volume
in the question the mass is given in grams so will convert it into kg,
10 g = 0.01 kg
density= 0.01/ 20 = 1 / 2000 = 0.005 kg/m^3
Answer: Maybe he has the heater on
Explanation: If there is that much temperature then it has to be from something heated.
I think this is because the particles don't know or care about each other,
and they act completely without any peer pressure. The direction in which
any one particle vibrates is completely random, and there is no connection
or influence among the particles. That means that any direction is just as likely
as any other direction for the next vibration, and they all wind up vibrating in
different directions. There is a tiny tiny tiny tiny chance that all of them could
vibrate in the same direction for just an instant; if that ever happened, the rock
would suddenly jump up in the air. That's actually true, but the chance is so tiny
that it hasn't ever happened yet. In fact, the chance is so tiny, that when scientists
do their calculations of particle vibrations, they assume that the chance is zero,
and that makes the calculations simpler.
