Answer:
physics and math tutor
Save my exams
Explanation:
hii! for PTM(physics and math tutor) you simply type in the search bar for example in. physics Units and measurements past papers.Then the first option would be PTM(physics and math tutor) and you click on it and it would give you on the left side Revision Notes, flashcards and practice questions. This site has helped me so much and I hope this helps you too (by the way PTM has for all 3 sciences and math too) just simply type the lesson name along with past paper and click on the first link and you'll get yourself your answers!!!! hopefully this helps!:))
Answer: It will increase the length of the day
Explanation: The polar ice caps contain the solid ice particles found around the polar regions,an increased temperature is a major cause of the melting of the polar ice Caps. When the polar ice caps melt especially in huge volumes they increase the amount of water flowing into the Sea this will cause a rise in the volume of the sea.
This rise in sea level will add some weights to Earth, making the Earth to rotate slightly lower than its normal speed,a slower rotation will lead to longer days.
You can use the impulse momentum theorem and just subtract the two momenta.
P1 - P2 = (16-1.2)(11.5e4)=1702000Ns
If you first worked out the force and integrated it over time the result is the same
Answer:
Metal is a tougher material to cut though, so the blades must be shorter to create more pressure to break through the metal. Paper on the other hand is easier to cut through so the blades can be longer in order to cut more in each snip.
