The time it took her to drive 2 km is 11.43 seconds, because sonverting kilometers to meters, it is 1000 meters to every kilometer, and she travels 2 kilometers, which is two-thousand meters. Then to find the time you need to divide the time by the speed, and with that you get 11.4285714286, or 11.43 seconds.

Answer:

11.4  s

Explanation:

The relation among distance (d), speed (s), and time (t) is

d = st                  Divide both sides by s and transpose

t = d/s

d = 2 km = 2000 m

s = 175 m/s         Calculate t

t = 2000/175

t = 11.4 s

Ways to reduce your carbon footprint.
sergejj [24]

Answer:

  • Avoid driving as much as you can
  • Avoid plastic in general (Plastic is usually not recycled, despite what people say. It ends up in landfills, the ocean, or it is burned)
  • Don't buy fast fashion (Clothes that are made in bulk by factories usually in Bangladesh. They are trendy but bad for the environment. Instead, shop at thrift stores.)
  • Don't waste food! Stop throwing out those leftovers, and make sure you eat everything on your plate.
  • Try to switch to renewable energy. (Use solar panels or find lights that conserve energy. Also, these options most likely cost less :)
  • Try to cut back on your meat intake. (I am a pescatarian who loves meat. I started this diet in 4th or 5th grade because it was a dare. I know, it was a crazy dare, but hey I don't back down! It's been about 5 years now and I'm still going strong. If me - a meat lover - can do it, you can to :)

Answer:

The pressure of the gas will  "increases by a factor of four."

Explanation:

The absolute zero in other words called as the absolute temperature. Whereas the absolute zero is the least possible temperature. In which nothing will remain cold and no heat can be released or present in the substance. When it is described in the figure it will be, –273.15 degrees Celsius on the Celsius scale. and  0 K on the Kelvin scale. This absolute temperature concept has been raised from the third law of the thermodynamics.

Find the percent composition of each element in KMnO4
VARVARA [1.3K]
The way you want to find the percent composition would be by breaking down the problem like so:

K= atomic mass of K which is 39.098
Mn = atomic mass of Mn which is 54.938
O= atomic mass of o which is 15.999

Then you want to add 39.098+ 54.938+ 15.999 and you get 110.035 which is the molar mass for KMnO

Then you want to take each molar mass and then divide it 110.035 and multiply by 100

Ex. K = 39.098/ 110.035 and the multiply what you get by a 100

You do this for the other elements as well good luck!
