Acceleration = Change in velocity / time taken
= (5 - 15) / 2
= -5 ms^-2
Answer:
a) 
, b) 
Explanation:
a) The magnetic force experimented by a particle has the following vectorial form:
The charge of the electron is equal to 
. Then, cross product can be solved by using determinants:
The magnetic force is:
b) The charge of the proton is equal to 
. Then, cross product has the following determinant:
The magnetic force is:

Answer:
Chemical energy is the potential of a chemical substance to undergo a chemical reaction to transform into other substances. Examples include batteries, food, gasoline, and etc. Breaking or making of chemical bonds involves energy, which may be either absorbed or evolved from a chemical system
Answer:
The correct answer is - 43%.
Explanation: The increase in CO2 between these two suggested periods is approximately 43%. Even though it is a natural process that the CO2 levels vary in the atmosphere, still this is not the same case nowadays. Nowadays, or rather in the past few decades, apart from the natural increase of CO2 in the atmosphere, it has seen a much more increased levels because of the human activity. The industrial facilities and the vehicles, the cutting of the forests and burning the wood (there's both release of CO2 from the burning of the trees and loss of natural accumulator of the CO2), are just some of the more important human activities that contribute to a significant rise in the CO2 levels.
