It would be C because you would do m divided by s squared and you would get 0.11 but you would round it to 0.12
Given , Speed of light = 3 × 10⁸ m/s
Distance = 40 × 1.61× 1000 m
= 264400 m
We know that, speed = distance/time
so, time = distance/speed
t = 264400 / 3 × 10⁸
t = 0.00881333 sec Approx
The answer is 0.00881333 sec Approx
Answer:
4.78atm
Explanation:
From the question, we obtained the following:
P1 (initial pressure) = 3.5 atm
T1 (initial temperature) = 200K
T2 (final temperature) = 273K
P2 (final pressure) =?
Using P1/T1 = P2/T2, the final pressure can be obtained as shown below:
P1/T1 = P2/T2
3.5/200 = P2/273
Cross multiply to express in linear form as shown below:
200 x P2 = 3.5 x 273
Divide both side by 200
P2 = (3.5 x 273)/200
P2 = 4.78atm
Therefore, the pressure at 273K is 4.78atm
Answer:
ch4 + 2o2 gives co2+2h2o +891kj
Explanation:
becoz 891kj heat energy is given out
exothermic process means heat energy is given out/ released
Answer:
If you're talking about a Sulfur ion, there are 13 electrons.
Explanation:
Sulfur originally had 16 electrons in its atom.
A charge of +3 means that sulfur must have lost 3 electrons, and therefore needs to gain back 3 electrons to achieve its atomic configuration.
