The GOES system of satellites, which tracks weather and other things, is in a geosynchronous orbit, 36,000 kilometers (22,000 miles) above the earth. These satellites travel at about 11,000 kilometers per hour (7,000 miles per hour).
You look at the least number of significant figures on the numbers you use in your calculation. That will determine the number of significant figures in your final answer.
Answer:
The Internet (social media to be precise)
Explanation:
False science are purported scientific conclusions drawn without any scientific data or procedures followed to arrive at such conclusions. These purported conclusions would have been irrelevant or not widespread without the internet or social media but the easy accessibility to social media globally has made "everyone" to be a scientist or even a publisher without scientific steps.
Some innocent individuals also help share (on the internet) these false science because of the inability to differentiate between the real scientific process and the ones done without any/some due scientific processes hence assisting in promoting these false science unknowingly. If there were no internet, these false sciences would not be this widespread as information will not travel this fast.
Answer:
Answer:
6.68 x 10^16 m/s^2
Explanation:
Electric field, E = 3.8 x 10^5 N/C
charge of electron, q = 1.6 x 10^-19 C
mass of electron, m = 9.1 x 10^-31 kg
Let a be the acceleration of the electron.
The force due to electric field on electron is
F = q E
where q be the charge of electron and E be the electric field
F = 1.6 x 10^-19 x 3.8 x 10^5
F = 6.08 x 10^-14 N
According to Newton's second law
Force = mass x acceleration
6.08 x 10^-14 = 9.1 x 10^-31 x a
a = 6.68 x 10^16 m/s^2
Explanation:
Answer:
t = √ 2y₀ / g
if they are at the same height, all the bullets must carry the target, since when advancing the height decreases
Explanation:
In this exercise we see that the bullets are fired horizontally so the time it takes to reach the ground is
y = y₀ + t - ½ g t²
as they are fired horizontally their vertical velocity is zero and the height upon reaching the ground is zero y = 0
0 = y₀ - ½ g t²
t = √ 2y₀ / g
from here we can see that the time it takes for the bullets to hit the floor depends only on the initial height
Therefore, all the bullets that come out of the same height reach the ground at the same time, but at a different distance, so if one misses the target, everything must fail since reaching the target is below the initial height.
The horizontal distance traveled by the bullets is
x = v₀ₓ t
v₀ₓ =v₀
x = v₀ √2y₀/g
For a more precise calculation we should know the height of the target and the bullets, but if they are at the same height, all the bullets must carry the target, since when advancing the height decreases
