Find the pressure if 100n force exerted on 20 square meters area

Answer»

GIVEN :-

  • Force = 100 N
  • Area = 20 m square

To FIND :- PRESSURE exerted by any object

Solution :-

we know that,

=> Pressure = Force / Area

=> Pressure = 100 / 20 pa

=> Pressure = 50 pa

Therefore pressure exerted by object is 50 pa.

___________________

More information:-

  • Force SI unit is NEWTON or N
  • Pressure SI unit is Pascal or pa.

Nitrogen(atomic number 7)and phosphorus (atomic number 15) belong to group 15 of the periodic table. write the electronic configuration of these two elements. which of these will be more electronegative? why?​

Answer»

NITROGEN

N(7)=2,5

Phosphorous

P(15)=

2,8,5

N is more electronegative than P.

From TOP to bottom down a group, electronegativity decreases. This is because number of shell increases down a group, and thus there is an increased DISTANCE between the valence electrons and NUCLEUS, or a greater atomic radius

How many cubic kilometers of land ice decrease in Antarctica since 2002?Explain it.....​

Answer»

Explanation:

Data from NASA's GRACE and GRACE Follow-On satellites show that the land ice sheets in both Antarctica (upper chart) and Greenland (lower chart) have been losing mass since 2002. The GRACE mission concluded science operations in June 2017.

GRACE Follow-On began data collection in June 2018 and is now continuing the mass change data record for both ice sheets. This data record includes the LATEST data processing improvements and is continually updated as more data are COLLECTED (with a lag of up to TWO months).

Note: You now need to create an Earthdata ACCOUNT to access NASA's ice sheet data. Register here for free. Once logged in, click "HTTP" under the charts on this page to access the data.
