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!:))
The reaction of the half-life is a description of the needed time for the reactant to deplete.In the first order reactions formula, k is considered as the first order rate constant whose unit is denoted as 1/s. Hope this helps.
Answer:
-0.7 m/s
Explanation:
Initial velocity (u)= 2.5 m/s
Acceleleration (a)= -0.8 m/s^2
Time taken (t) = 4 seconds
Hence,
v=u+at [1st Equation of motion]
v=2.5+-0.8*4
v=2.5-3.2
v=-0.7 m/s
Note that the negative sign indicates that the ball has changed direction and rolls downwards with gravity
