Pressure given by:
Pressure=(force)/(area)
Force=Mass*gravitational pull
Mass=34Kg
gravity=9.80
so,
force=34*9.8=333.2
thus;
pressure=333.2/25=13.328=13.3 N/cm^2
Hope this helped :)
Explanation:
There are several ways to define acids and bases, but pH and pOH refer to hydrogen ion concentration and hydroxide ion concentration, respectively. The "p" in pH and pOH stands for "negative logarithm of" and is used to make it easier to work with extremely large or small values. pH and pOH are only meaningful when applied to aqueous (water-based) solutions. When water dissociates it yields a hydrogen ion and a hydroxide.
Answer:
reflection
Explanation:
the moon reflects sunlight causing it to look brighter. the sun is not a medium as light doesn't require a. medium to travel. nor is a moon concave...

Answer:
1.1713 moles
Explanation:
RFM of N2O5= (14*2)+(16*4)=108
Moles of N2O5= Mass/RFM= 63.25/108= 0.5856 moles
Mole ratio of N2O5:NO2 = 2:4
Therefore moles of NO2= 4/2*0.5856= 1.1713 moles
Answer:
Take a long time
Explanation:
Geology is defined as a science mostly concerned with the study of the history of the earth as recorded in different rocks formations.
Geologic processes are events that occur on a geological timescale which may span across many centuries.
The four major geologic process are known to include; impact cratering, volcanism, tectonics, and erosion.
